Description

Technical field

The present invention relates to medicine and can be used in neurology, psychiatry, neurophysiology, neuropsychology and a number of other modern neurosciences that study the human brain and its behavior, as well as in the field of information and communication technologies when creating artificial intelligence, robotics and architecture.

State of the art

Virtual reality is widely applicable to the treatment of mental illness (Thompson-Butel, A. G., Shiner, C. T., McGhee, J., Bailey, B. J., Bou-Haidar, P., McCorriston, M., & Faux, S. G. (2018). The Role of Personalized Virtual Reality in Education for Patients Post Stroke-A Qualitative Case Series Journal of Stroke and Cerebrovascular Diseases doi:10.1016/j.jstrokecerebrovasdi).

At the same time, it acts on the cognitive, emotional and physical state of a person with the help of hardware and software. A number of authors point out that the hardware affects only the emotional state of a person (with the exception of cases of physical rehabilitation, when it is necessary to replace the lost function or use an alternative information input channel), while the software causes a change in the cognitive, emotional and physical parameters of patients. (Howard, M. C. (2018). Virtual Reality Interventions for Personal Development: A Meta-Analysis of Hardware and Software. Human-Computer Interaction, 1–35. doi:10.1080/07370024.2018.1469408)

When presenting VR therapeutic content to a patient, personalized to their neurophysiological parameters, there are significant differences in the emotional response and an increase in the level of participants' motivation. (Kim B, Schwartz W, Catacora D, Vaughn-Cooke M. Virtual Reality Behavioral Therapy. Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 2016;60(1):356-360. doi:10.1177/1541931213601081). Physicians involved in VR-assisted mental health care note the importance of VR personalization for mainstreaming clinical practice. (Vincent C, Eberts M, Naik T, Gulick V, O'Hayer CV. Provider experiences of virtual reality in clinical treatment. PLoS One. 2021 Oct 29;16(10):e0259364. doi: 10.1371/journal.pone.0259364 PMID: 34714889 PMCID: PMC8555834 Multimedia Experience (QoMEX) doi:10.1109/qomex.2019.8743335 Hu, X., & Wang, K. (2010) Personalized Recommendation for Virtual Reality 2010 International Conference on Multimedia Technology. doi:10.1109/icmult.2010.5631134).

A method for personalizing virtual reality is described, based on the effect of two-way interaction between VR content and the patient. A dynamic, non-static virtual reality scenario is used, which can be adjusted during the session depending on the specific needs of the patient, by measuring galvanic skin responses and adapting the virtual reality content accordingly. (Kritikos, J., Alevizopoulos, G., & Koutsouris, D. (2021). Personalized Virtual Reality Human-Computer Interaction for Psychiatric and Neurological Illnesses: A Dynamically Adaptive Virtual Reality Environment That Changes According to Real-Time Feedback From Electrophysiological Signal Responses. Frontiers in human neuroscience, 15, 596980. https://doi.org/10.3389/fnhum.2021.596980).

The disadvantage of this method is the lack of a single morphometric indicator between the content of virtual reality and neurophysiological changes that occur in the human brain. Which, in turn, complicates the process of predicting the reaction to VR content, and bulky equipment complicates the independent conduct of psycho-corrective sessions.

There is also a method in which content personalization is based on the analysis of behavioral and logical errors. The disadvantage of this method is the narrow possibility of using it only within the framework of developing new skills during training, as well as the lack of correlation between the neurophysiological parameters of the human brain and virtual reality content. (Lang, L. Wei, F. Xu, Y. Zhao and L. -F. Yu, "Synthesizing Personalized Training Programs for Improving Driving Habits via Virtual Reality," 2018 IEEE Conference on Virtual Reality and 3D User Interfaces (VR), 2018, pp. 297-304, doi: 10.1109/VR.2018.8448290.).

A known method of psycho-physiological correction of the psychological state using virtual reality of a personalized geometric shape (RF patent No. 2753234), including the stages of its impact using a visualization tool.

At the same time, internal volumetric images of closed spaces are shown in the form of sequentially alternating frames, having different ratios of the areas of their internal surfaces to the areas of the minimum imaginary spheres inscribed in these spaces, provided that the image of one space has the indicated ratio less for a person than the ratio of the free area the surface of the cerebral hemispheres, taking into account its convolutions and furrows, to the area of the minimum imaginary sphere described around them.

Moreover, the session is carried out in two phases, in which the dimensions of the displayed spaces are changed. In the first phase, the dimensions of the geometric figures are changed, which determine the forms of the closed space in the direction of increasing the ratio of the areas of their internal surfaces to the areas of the minimum imaginary spheres inscribed in these figures. Then, in the second phase, the specified dimensions are changed in the opposite direction. The time of the second phase of exposure is 18-30% of the first phase with a total session duration of 5-25 minutes, this method does not take into account the use of virtual space in the form of a finite area of open space, which has both its own physical features that significantly distinguish it from closed spaces, so and features of human perception of open spaces, which largely carry unconditional genetically conditioned information for humans.

This does not allow direct use of the above method, both in terms of replacing the demonstration of closed spaces with open ones, and in terms of the number, sequence, time intervals and technique for performing a virtual reality demonstration.

There is a known method (RF patent No. 2725965), which allows, on the basis of a single system-forming factor, which is a minimum of energy costs in interaction with the environment, both within the central nervous system and the human environment, in principle to evaluate the morphological and functional features of the brain during its functioning and interaction with end area of open space.

At the same time, the brain and the human environment are presented in the form of simply connected areas, homeomorphic to the sphere, which is a structural attractor of the considered system of interaction between the human brain and the surrounding space.

At the same time, in contrast to closed spaces, in this method, to describe the properties of space, the ratios of the areas of their light surfaces to the areas of their projections on the minimum imaginary sphere described around the Earth at the highest altitude above ocean level are considered, taking into account the height of artificial structures located respectively in the territories of these areas .

At the same time, a relationship was established between the parameters of the final area of open space on the example of a gently undulating plain, mountainous terrain and the anthropogenic relief of a modern city and the morphological and functional characteristics of the patient's cerebral hemispheres.

Here, the objectively existing morphophysiological features of the cerebral hemispheres of the patient are taken into account, which determine the perception of the surrounding space by a person and have a significant impact on his psychophysiological state, as well as the features of the open spaces surrounding the person. In addition, this method allows you to plan and create architectural objects, including VR objects, taking into account the individual needs of the human brain, providing maximum adaptation and optimal functioning.

The present invention is aimed at improving the effectiveness of the psychophysiological correction of the patient's psychological state by creating and using a virtual reality of a personalized geometric shape in the form of a finite area of open space.

The invention can be used:

- for personalized psychophysiological correction of the psychological state, therapy and prevention of mental disorders;

- in order to study the structure and functioning of the cerebral hemispheres during their accommodation in open, including virtual space;

- when creating and researching artificial intelligence and personalized robotics;

- when creating an anthropogenic relief of a personalized geometric shape of modern cities, in architecture.

The technical result is to increase the effectiveness of the psychophysiological correction of the psychological state due to the combined individual psychological and neurophysiological effects of virtual reality of a personalized geometric shape on the human central nervous system.

The essence of the invention

The specified technical result is achieved by means of a set of features given in the relevant paragraphs of the claims.

The method of psycho-physiological correction of the psychological state using virtual reality of a personalized geometric shape in the form of a finite area of open space includes stages of its impact using a visualization tool. At the same time, internal three-dimensional images of spaces are shown in the form of sequentially alternating frames, and the session is carried out in at least one series containing several phases in which the dimensions of the displayed spaces are changed.

According to the invention, at least finite areas of open spaces are shown, having different ratios of the areas of their light surfaces to the areas of their projections on the minimum imaginary sphere circumscribed around the Earth at the highest altitude above ocean level, taking into account the height of artificial structures located respectively in the territories of these areas .

At the same time, the condition is observed that in at least one demonstrated area of open space, the indicated ratio is less than in the patient, the ratio of the free surface area of the cerebral hemispheres, taking into account the convolutions and furrows, to the area of the minimum imaginary sphere described around them, and this space is demonstrated first.

The session is carried out, at least, in the form of a series, including three phases, while in the first phase the dimensions of the above final region are changed in the direction of decreasing the corresponding ratio.

Then, in the second phase, the dimensions of the displayed area are further changed with an increase in said ratios higher than the corresponding ratio of the cerebral hemispheres of the patient.

Further, in the third phase, the dimensions of the area being demonstrated are changed to a ratio smaller than the corresponding ratio of the cerebral hemispheres of the patient, and the duration of the first phase is 1-10 percent, and the third phase is 15-32 percent of the second phase with the duration of one session series of 4-35 minutes.

According to one of the preferred embodiments of the method, additionally before the session, macroencephalometry of the cerebral hemispheres is performed using a hardware computer-diagnostic complex with the determination of the ratio of the free surface area, taking into account the convolutions and furrows, to the area of the minimum imaginary sphere described around them.

According to another preferred embodiment of the method, at least one of the following studies is additionally carried out according to a well-known method: questioning the patient's psychological state before and after the session, measuring his pulse, blood pressure, functional near-infrared spectroscopy, electroencephalography, and studying the level of oxygen saturation in the blood.

According to another preferred embodiment of the method, VR glasses are used as a visualization tool.

Brief description of the drawings

For a better understanding, but by way of example only, the present invention will be described with reference to the accompanying drawing, FIG.

Detailed description of the implementation of the method and its use.

The use of this method is based on the objectively occurring neurophysiological processes in the human brain in a virtual environment that differs significantly from the natural environment in which a person spends most of his life.

At the same time, it should also be understood that the virtual environment distorts the forms of its use in comparison with the natural environment. So, for example, in a virtual environment, during virtual movement in a virtual space, a person does not experience muscle load, which is characteristic of his movement in a real environment and is primarily due to gravitational forces.

This significantly changes the signals coming to the brain from the muscles, internal organs and systems of a person, which, when he is in a normal environment, balance the signals received during visual perception of the real surrounding space.

Therefore, during virtual movement in virtual space in the patient's brain, there is a dominant signal coming from the visual perception of the geometric forms of space, between which and the patient's brain, taking into account its morphometric characteristics, there is a certain correlation. This contributes to the formation of a kind of reserve of unused energy resources, which can additionally be used by the patient's brain.

Given the above, the method of psychophysiological correction using virtual reality of a personalized geometric shape includes the stages of its impact with the help of a visualization tool through the organs of vision on the human brain.

At the same time, internal three-dimensional images of finite areas of open spaces are shown in the form of sequentially alternating frames.

As a means of visualization according to one of the preferred embodiments of the method, for example, VR glasses can be used. For these purposes, VR lenses, a VR helmet or a 3D display can also be used, since any of these tools performs only one main action to form a virtual space and its effect through the organs of vision on the patient's brain.

At the same time, the use of any of these visualization tools does not change the essence of the method under consideration and does not significantly affect the achievement of the planned technical result.

At the same time, the mention in the present description of the available visualization tools that can be used in the implementation of the present method allows a more detailed understanding of the essence and productive implementation of the present method.

As virtual reality (VR) objects, for example, 3D models of finite areas of open spaces in the form of an anthropogenic relief of a modern city, mountainous relief, plain, water surface, presented as a VR object of each mentioned area separately or in various versions of them can be used. compositions. The present method also allows the additional use of VR objects in the form of an enclosed space that can be shown in the overall story.

These virtual reality objects can be obtained by field measurements of real natural and anthropogenic objects, for example, using small aircraft or space observation tools, followed by computer simulation and creation of 3D models of a specific VR object. It is also possible to create a specific VR object only using computer simulation, taking into account, for example, the results of the study of visual space. (Kovalev A.M. Description of the visual space in the Klein and Poincaré models. Optical information technologies, elements and systems. AUTOMETRIYA, 2006, volume 42, No. 4. P.-57).

It should be noted that the hardware and software for performing the above actions to create specific VR objects, their compositions and plots, as well as the process of their demonstration using the above visualization tools, are well known and widely used. Also well-known hardware and software for macroencephalometry of the cerebral hemispheres, which will be mentioned below in this description.

Therefore, there is no need to detail the list and sequence of actions to create and measure VR objects and macroencephalometry of the cerebral hemispheres, since these actions do not change the essence of the claimed method and do not significantly affect the achievement of the technical result.

When implementing the present method, the session is carried out in the form of at least one series containing several phases in which the dimensions of the displayed VR spaces are changed.

The demonstration of VR objects in the plot in the form of series is due to the peculiarities of the perception of visual information by the human brain in this case, in which repetitions of the series are necessary to achieve the greatest effect.

It should be understood that in order to achieve the planned technical result, it is sufficient to demonstrate one series of virtual spaces under consideration. At the same time, a session can contain multiple series. According to their content, they can be of the same type or different. At the same time, the number of series and their content depend on the task being solved, for example, on the psychological rehabilitation of a patient.

The internal content of at least one series is characterized by phases within which the order of changing the dimensions of the internal surfaces of the displayed spaces, their dimensions and the duration of the implementation and demonstration of these actions are established. The sequence of phases in the series is also important.

The internal filling of the phases can also be the same type in several series or differ for each series, depending on the tasks being solved.

According to the method under consideration, to increase the effectiveness of the psychophysiological correction of the psychological state of the patient, he is shown at least finite areas of open spaces having different ratios of the areas of their light surfaces to the areas of their projections on the minimum imaginary sphere described around the Earth at the highest altitude above ocean level, taking into account the height of artificial structures located respectively in the territories of these regions,

Further, this ratio is referred to as the shape factor of the finite area of open space, which characterizes its structural attractor.

This attractor, in turn, has a significant impact on endogenous processes occurring inside the finite area of open space, and also determines the nature of their impact on neurophysiological processes in the brain when information about these spaces is introduced through the organs of vision into the brain in the form of virtual reality objects.

The specified form factor (according to research in the patent of the Russian Federation No. 2725965) approaches unity for open spaces in the form of, for example, plains (including gently undulating) or water bodies. It has an average value for relatively large areas of mountain ranges and a maximum value for the anthropogenic relief of modern cities.

At the same time, the mentioned shape factor for the finite area of open space depends significantly not only on the terrain, but also on the ratio of the geometric dimensions of the corresponding finite area.

At the same time, the use of finite areas of open space, for which their shape factor is known, allows you to control the process of influencing the brain of a particular patient and thereby achieve a predictable effect on his psychophysiological state.

This will allow to achieve relaxation of the zones of excessive excitation or, at least, to reduce the internal residual mechanical stresses in them, which is essential for further controlled effective impact on the patient's mental state.

Such a shape is guaranteed, for example, to be an area of gently undulating plain, which has a shape factor approaching unity, and which, as a rule, is less than the shape factor of the patient's cerebral hemispheres.

Here, as mentioned above, as the final area of open space, for example, a 3D model of a section of a gently undulating plain, a mountainous area or a city, or another VR object having signs of a finite area of open space, can be used.

Since the concept of a finite area of open space is described in detail in the prior art (for example, patent RU 2725965), in this case there is no need to reiterate its features in detail.

At the same time, under the finite area of open space, in this case, VR should be understood as a specific fragment of the territory with its boundaries on the ground. Moreover, the indicated fragment of the territory is perceived holistically and from the inside, while part of the real fences in it are replaced by conditional ones, for example, the sky and the panorama (Agranovich-Ponomareva E.S. Architectural design: word-ref. Text / E.S. Agranovich-Ponomareva. - Rostov n / D: Phoenix, 2009. - 342 p.).

At the same time, the choice of VR objects in the form of finite areas of open spaces as the main obligatory for demonstration is due to the fact that, firstly, their demonstration in accordance with the present invention is in itself a psychotherapeutic basic plot that carries unconditional information about the living space, which is one of the bases of the patient's genetic memory, used by him largely unconsciously to carry out his life cycles.

Secondly, the displayed end areas of open space act as the basic arena of the patient's living space, on which stationary objects can be located, for example: buildings, structures that have a significant impact on the shape factor of the end area of open space, and, very importantly, on Based on this VR object, a psychotherapeutic plot with an extensive scenario can be additionally demonstrated according to indications.

It should be understood that when a patient is shown a specific object of virtual reality, for example, in the form of a finite area of open space of the anthropogenic relief of a modern city, he virtually sees at a time at least a part of the displayed space and can virtually move inside it, approaching or moving away from one or another its parts.

At the same time, despite the demonstration of an imaginary space and the virtual movement of the patient in this space, real physiological processes occur in his brain, which have a significant impact on his psychophysiological state. These processes are largely not compensated by nerve impulses coming from the muscles, as, for example, when a person actually moves in real space, that is, in terms of movement, an effect similar to weightlessness is observed.

This significantly increases the effect of the demonstrated space on certain parts of the brain by removing significant burdens from it and releasing the released energy.

Another feature of the finite area of open space is the presence of a firmament bounded by a sphere circumscribed around the earth at the highest altitude above the ocean level, located on the territory of this area. At the same time, it is known that the sphere has a minimum shape factor equal to one, which additionally contributes to an increase in the effectiveness of psychophysiological correction.

Demonstration in the form of a VR object of a finite area of open space with its characteristic structural attractor, selected depending on the structural attractor of the patient's cerebral hemispheres, in comparison with closed spaces, makes it possible to widely use the effect of physical and psychological perspective in the form of a horizon or sky in achieving the patient's expectations, thereby excluding the phenomenon of "learned hopelessness and helplessness" (K. Richter, 1957; M. Seligman, 1964).

This effect of physical perspective is primarily due to the physical properties of a finite area of open space. So for this VR object, the presence of a transparent border in the form of a sky and a horizon, as well as a possible subject distance from the patient, in contrast to closed spaces, determines not only specific unconditional subject information, but also unconditional information that reveals the prospect of opportunities to achieve the patient's subconscious expectations for preservation and dissemination of their genetic information, which significantly increases the effect of psychotherapeutic influence.

At the same time, in the brain, in particular in the cerebral hemispheres of the patient, which have a high entropy of the processes taking place in them, an idea is formed about the space in which he is virtually placed, accompanied by the excitation of certain areas of the cortex of the hemispheres of his brain and the occurrence of stress-strain states in them.

These states are accompanied by the appearance of continuously changing internal (residual, memory-related, and working) mechanical stresses and electromagnetic properties, at least in the cerebral cortex. Moreover, these processes take place taking into account the anisotropy of properties, both of individual sections of the cortex and the entire brain as a whole, due to their shape, size and density, and the anisotropy of the properties of the demonstrated finite area of open space, which, like the brain, is characterized by a high entropy of endogenous processes occurring in him.

Since the displayed spaces have different geometric shapes of internal surfaces and volumes, they will have different effects on certain parts of the patient's cerebral hemispheres, in which at the time of the session certain excitation zones were formed that have a certain cognitive background and are characterized by residual mechanical stresses. and electromagnetic properties.

From this it follows that for guaranteed relaxation of stable zones of excitation in the cerebral cortex, it is necessary to enter into it information about the space, which has a smaller form factor than the cerebral hemispheres.

Therefore, when implementing the method under consideration, in order to achieve a significant result, it is necessary to observe the condition that, in at least one demonstrated area of open space, the above ratio is less than in the patient, the ratio of the free surface area of the cerebral hemispheres, taking into account convolutions and furrows, to the area of the minimum imaginary sphere , described accordingly around them, and this space is shown first,

Further, this ratio is referred to as the shape coefficient of the cerebral hemispheres, respectively, characterizing its structural attractor.

Since the coefficient of the shape of the cerebral hemispheres is individual and can vary for each patient, at least within the range of 3.5-5.3, the said coefficient is selected from the above limits. In this case, the limits are due to the possible morphological characteristics of the hemispheres of the human brain.

A guaranteed form of a finite area of open space, in which the form factor is, as a rule, greater than that of the cerebral hemispheres, is, for example, the anthropogenic relief of modern cities.

This further details the program for demonstrating volumetric spaces, based on the individual characteristics of the cerebral hemispheres of the patient, and thereby improves the technical result of the present method.

When demonstrating a personalized geometric shape in a chain of successive VR frames, which have shape coefficients of the latter greater than those of the cerebral hemispheres, activation of neurons in other functional areas of the brain is achieved and, thereby, its efficiency increases, due to the individual characteristics of the patient's brain, which until then largely unused.

When implementing the present method, the session is carried out at least in the form of a series, including three phases, while in the first phase the dimensions of the above final region are changed in the direction of decreasing the corresponding ratio. Moreover, the duration of the first phase is from 1 to 10 percent of the second phase.

However, it should be noted that the session may contain a different number of series, and the series may differ in the duration of the phases, the value of the shape coefficients of the displayed spaces. A session may also contain sequentially shown spaces outside of series, that is, between series or, for example, after the first series has been shown.

As an example, consider figure 1, which shows a session schedule in accordance with the present method, containing two series, each of which contains three phases, where the first phase is denoted by the letter A, the second by the letter B and the third by the letter C.

At the same time, the values of the shape coefficients of the displayed volumetric images and the cerebral hemispheres are indicated on the vertical axis of the graph. The horizontal axis of the graph indicates the duration of the demonstration of each volumetric image in two series.

Curve I shows a smooth change in the shape coefficients of the displayed spaces. Line II corresponds to the values of the shape coefficients of the cerebral hemispheres of the patient.

In this case, consider two series of demonstrations of the above three-dimensional images, representing two waves of changes in the coefficients of the form of the displayed spaces (see figure 1).

Moreover, each wave in this case includes the first phase, the introductory (preparatory) section A, the second phase - the section of the growth (rise) of the shape factor of the displayed finite area of space B and the third phase - the section of the decrease (fall) of the shape factor of the displayed space C.

It should be understood that these areas can refer both to one smoothly changing space, and to various forms of the displayed spaces.

The graph also shows that the shape factor of the space shown first in the session (first phase A) is less than the shape factor of the patient's hemispheres, but greater than one, since this is the minimum possible value of the shape factor of the space shown, which in this case cannot be reduced. Therefore, for example, VR can be shown first as a fragment of a gently undulating plain.

Resizing the VR object in the form of a finite area of open space, carried out in the first phase of the series and providing at the beginning a decrease in its shape factor, is a fundamentally important aspect. In particular, in the depicted graph (FIG. 1), the duration of the first phase A was 16 seconds. Or 8% of the second phase B.

In connection with the above properties of the finite area of open space, in particular, the presence of a spatial perspective and the possession of information unconditional for the patient, the patient's internal subconscious opposition to the information displayed in the form of a VR object is significantly reduced or even eliminated, that is, almost unhindered entry into contact with patient and preparing the basis for further productive impact on the patient's subconscious.

According to the method under consideration, in the second phase B of the series, the dimensions of the displayed area are further changed with an increase in the indicated ratios. In this case, the change in the size of the demonstrated area in the direction of increasing its shape factor is carried out up to its value exceeding the shape factor of the cerebral hemispheres of the patient.

For example, in figure 1 in the second phase B of the first series, the maximum value of the shape factor of the displayed space is 4.9, that is, it is not significantly higher than the shape factor of the patient's cerebral hemispheres (line II on the graph), equal to 4.5. At the same time, the duration of the second phase B demonstrated on the presented graph is 3.2 minutes.

It should be noted that the amount of said excess is usually sufficient for the first series of VR demonstrations. It can be increased in subsequent series of the session, as indicated in Fig.1. However, this excess may be greater in the first series, depending on the indications of the problem being solved, due to the patient's condition.

Further, in the third phase C, the size of the area being demonstrated is changed to a ratio smaller than the corresponding ratio of the patient's cerebral hemispheres, and the duration of the third phase is 15-32 percent of the second phase, with a session duration of 4-35 minutes.

On the shown graph, the shape factor of the demonstrated space at the end of the third phase C decreases to the values of the first phase A. However, it should be noted that the minimum values of the shape factor of the demonstrated space during the third phase can be higher than the values of the first phase A, provided that the percentage ratio for the duration of execution with the second phase B and the values of the smaller form factor of the patient's hemispheres.

The maximum limit of the time interval of the session is due, on the one hand, to the sufficiency of its impact on the psychophysiological state of the patient to create a stable effect of psychological relaxation, and on the other hand, a decrease in this effect with an increase in the duration of the session due to overexcitation of certain areas of the cerebral cortex.

At the same time, in the process of demonstrating images, the change in the geometric shape of the virtual space is carried out abruptly or smoothly. With a smooth change in the shape of the displayed spaces, a more gentle effect on the individual's brain is provided. The formation of the sequence and duration of the demonstration of these three-dimensional images depends on the initial state of the patient, cognitive background and the goal of psychophysiological correction.

As a rule, the session should be carried out depending on the patient's condition for 4-35 minutes, since an effect is achieved that ensures an increase in the efficiency of his brain.

The recommended number of sessions, as a rule, can be up to 10 or more, depending on the patient's condition and obtaining a stable result. In this case, the method can be applied situationally, for example, to normalize the psychological state or prophylactically.

The minimum period of time for the session under consideration is due to the need to create a sustainable effect, taking into account the neurophysiological processes occurring in the patient's brain

At the same time, the stress-strain state of the cerebral hemispheres, both in general and in its individual parts, on the one hand, depends on the biochemical, electrical, biomechanical processes occurring in the brain, and on the other hand, it itself influences the course of these processes, blocking them or activating them. separate functional areas, and thus has a coordinating effect on the course of neurophysiological processes in the brain.

Together, the above processes form the process of thinking and remembering, and thus have a significant impact on the psychophysiological state of the patient.

At the same time, the above processes, accompanied by the stress-strain state of the cerebral hemispheres, both in general and in their parts, largely depend on their shape, size, tissue density gradient, topographic location of functional zones and excitation zones.

At the same time, the demonstration, in accordance with the present invention, of finite areas of open space with different coefficients of their shape, characterizing their structural attractors, and containing unconditional information with the effect of perspective (hope) makes it possible to exert a dominant predictive effect on the psychophysiological state of the patient, both in the volume of the entire brain with its individual structural attractor, as well as to its individual sections.

The possibilities of using this method are quite wide. For example, without changing the essence of the method, simultaneously with the demonstration of VR objects in the form of a finite area of open space, which is an additional arena for a psychotherapeutic plot related to the patient's condition, a well-known psychotherapeutic plot can be demonstrated in the form of VR, solving a specific problem, for example, to eliminate any phobia.

At the same time, the demonstrated end areas of open spaces can be the arena of a psychotherapeutic plot and / or directly enter into its composition, thereby increasing its effectiveness.

The considered method has a number of preferred implementations.

According to one of the preferred embodiments of the method, for a more accurate determination of the coefficients of the cerebral hemispheres, additionally before the session, their macroencephalometry is performed using a computer-diagnostic complex with the determination of the ratio of their free surface area, taking into account the convolutions and furrows, to the area of the minimum imaginary sphere described around each of them.

In accordance with another preferred embodiment, at least one of the following studies is additionally carried out according to a well-known method: questioning the patient's psychological state before and after the session, measuring pulse, blood pressure, functional near-infrared spectroscopy, electroencephalography, studying the level of oxygen saturation in the blood.

Additional questioning of the psychological state is carried out in accordance with one of the known methods used. The purpose of this questionnaire is to find out the actual psychological and mental state of the patient. This allows using an individual approach to form a personalized program of targeted impact on his brain.

An additional measurement also using well-known methods of pulse, blood pressure, functional near-infrared spectroscopy, electroencephalography, the study of the level of oxygen saturation in the blood, after the session, allows you to assess the patient's condition and most accurately plan the next session, which will reduce the rehabilitation time and increase the efficiency of using the method.

An example of the implementation of the method

As an example, let us consider in a generalized form the demonstration of one preferred embodiment of the method in the form of a series of VR demonstrations of specific finite areas of open spaces that can be an arena and an integral part of a psychotherapeutic story. This example of the implementation of the method will be simple and clear.

Moreover, it will testify to the possibility of creating a wide range of psychotherapeutic plots consisting of virtual spaces of personalized geometric shapes that significantly increase the effectiveness of the psychophysiological correction of the mental state of the corresponding states of patients.

However, it should be understood that when implementing the present method, it is possible to use other than indicated in the above demonstration example, internal volumetric images of the final areas of open spaces, including complex shapes, or in the scenario of a different psychotherapeutic plot, based on the patient's testimony.

For example, testing of the present method was carried out for patient "A", 36 years old, in need of psychological correction. A total of 7 sessions were conducted, lasting 17 minutes. every. Each session contained three series of the same type. Each series consisted of three phases. The result is positive.

Next, we consider in more detail the implementation of this method. In the case under consideration, before the start of the demonstration session of the above three-dimensional images of the end areas of open spaces, macroencephalometry of the cerebral hemispheres of the patient was performed and its individual shape coefficient was determined. It is equal to 4.5.

Next, a survey of the psychological state of the patient was carried out according to a well-known method that meets the clinical problem being solved. Next, the patient's pulse, blood pressure, and oxygen saturation in the blood were measured.

Further, in accordance with the schedule shown in figure 1, using VR glasses mod. Samsung HMD Odyssey - Windows Mixed Reality Headset was shown to the patient in three series in each session of internal three-dimensional images of the following spaces: a gently undulating plain, an anthropogenic city relief, and a mountainous area.

At the same time, as mentioned above, the vertical axis of the graph indicates the values of the shape coefficients of the displayed volumetric images and the cerebral hemispheres. The horizontal axis of the graph indicates the duration of the demonstration of each volumetric image in two series.

Curve I shows a smooth change in the shape coefficients of the displayed spaces. Line II corresponds to the value of 4.5 coefficients of the form of the cerebral hemispheres for the patient.

Next, consider in detail the schedule of the session shown in Fig.1. First, within 16 seconds. showed a finite area of open space in the form of a gently undulating plain having a form factor approaching unity, i. e. significantly less than the shape factor of the cerebral hemispheres (straight line II).

At the same time, the dimensions of the displayed area during phase A of the specified period of time were changed in such a way that the coefficient of its shape slightly decreased.

This manipulation is the introductory part of the session. Since the shape factor of the demonstrated gently undulating plain is much less than the shape factor of the hemispheres and changes especially smoothly in accordance with the presented graph, this contributes to the relaxation of both individual functional zones of the hemispheric cortex and the hemispheres as a whole, accompanied by a decrease in the magnitude of mechanical stresses in them, and in first of all tangential (tangential) form-changing mechanical stresses.

This allows the patient to smoothly enter the session due to a slight change in the form factor, without creating peak stress values, which can further reduce the effectiveness of this method, acting as a cognitive background.

In this case, zone A is repeated before each wave of change in the shape factor of the displayed finite area of open space.

Further, in this example, a smooth transition to the second stage (phase B), where the final area of open space is shown in the form of a mountainous area with a wide range of different reliefs. At the same time, the coefficient of the form of space is smoothly changed to values of 4.9, which is slightly greater than the coefficient of the form of the hemispheres (straight line II).

This contributes to the smooth formation of mechanical stresses, both in individual functional areas of the hemispheres, and in them as a whole, which has a significant impact on the biochemical, electrical, biomechanical processes that occur both in individual functional areas and in the whole in the cerebral hemispheres. In this case, what is important, the spatial multiconnectivity of the individual excited zones of the hemispheres changes in the direction of their single connectivity.

The indicated set of displayed volumetric images constitutes the ascending part of the first series of the graph. Thus, during the session, there is a controlled, which is very important, transition from relaxation of mechanical stresses in the cerebral hemispheres and their functional areas to an increase in these stresses.

Next, they demonstrate (phase C) a three-dimensional image of the final area, also a mountainous area, while smoothly reducing its shape factor to 1.3 with the transition to the demonstration of the plain. The plain is shown again in phase A, which is preparatory for the next wave of change in the shape coefficients of the displayed spaces.

The transition from the demonstration of a finite area of open space with the maximum shape factor value of 4.9 in this phase of the session to its value of 1.3 is a descending branch of the curve of the first series of the session. Moreover, its duration is significantly less than the duration of the ascending branch of the diagram (phase B) and is about 30% of it.

Thus, the change in the shape factor of the displayed series of internal spaces tends to the shape of the incident wave. This allows you to achieve the greatest effect of relaxation, following the increase in mechanical stress in the cerebral hemispheres, and as a result, it allows you to remove mechanical stress in individual functional areas of the hemispheres and prepare them for the perception of the next series of spaces.

Let's look at the next wave. Here, after the preparatory phase A, spaces are demonstrated with a smooth increase in their shape factor to a value of 6.1, which is greater than the shape factor of the patient's cerebral hemispheres.

At the same time, the final regions of the mountainous area are shown first, then, up to the value of the form factor of 6.1, the final region of the modern city in the form of a narrow street passing between high-rise buildings. This will be the ascending branch of the second wave of the session, which causes a significant increase in mechanical stress in the cerebral hemispheres of the patient.

Next, a descending branch (phase C) of the second wave of the session is formed, changing the dimensions of the displayed space to a shape factor of 1.9 with a smooth transition to a demonstration of a mountainous area, followed by a change in its shape factor to 1.3. This achieves the greatest effect on the psychophysical state of the patient.

In order to simplify the demonstration of the implementation of the present method, a detailed demonstration of an additional psychotherapeutic plot aimed at solving a specific problem is not described.

Further, depending on the patient's condition, the session can be repeated in an unchanged form or can be individually modified.

Further, after the session, in accordance with one of the preferred embodiments of the method, the psychological state of the patient is questioned. They measure his pulse, blood pressure and oxygen saturation in the blood and make a conclusion about the effectiveness of the first session, and then plan a program for further improvement of the patient.

Although the present invention has been described in some detail, various changes and modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
