DD224219A1 - DEVICE FOR THE ELECTROMAGNETIC INFLUENCE OF THE BRAIN WAVE PATTERN - Google Patents

Abstract

This invention serves the task of influencing the brainwave pattern externally by a veraenderliches electromagnetic alternating field. The aim is to calm the brain to support the transition from awake to sleep in the sleep-disturbed. In the electroencephalogram detectable brain wave pattern passes through each prevailing frequencies of 13 to 8 Hz down. These frequencies are assigned to the a waveband. The vibrations of the above-mentioned frequencies are generated in a generator whose frequency is controlled by a Saegezahngenerator within a corresponding time, which is required for falling asleep. In a downstream modulator, this signal is also changed by the Saegezahngenerator in its amplitude. The received oscillation is amplified in one power stage and used to generate an electromagnetic alternating field in two coils. These coils are incorporated vertically into a base. The device according to the invention operates completely unnoticed, is easy to use by the user and everywhere and simple in design and manufacture. It can also be used in the reverse functional sequence for the general activation of the cerebral cortex in case of lack of concentration.

Description

- 2 - ΔΧ3Λ

In the state of brain activity (work, attention), the various elementary generators are aroused in accordance with their functional pattern at various times. In the electroencephalogram there are many small rashes, d. H. high-frequency waves of small amplitude. The nerve cells do not work synchronously. When the specific activity of the individual elementary generators decreases and a person comes to rest, excitement often occurs simultaneously at the various nevus cells. They influence each other in the sense of increasing synchronization.

The cerebral cortex itself is only partially able to do so.

Synchronizing excitations emanate from deep-seated heifers as they enter sleep and sleep. Thus, the generation of brain sleep is an active process that significantly disturbed many people

The task of synchronization of the cerebral cortex can also take over an external system. In the transition from the conscious state of rest to the first phase of sleep, the so-called α-rhythm occurs. The waves extend from 13Hz to 8Hz. The electromagnetic field of this invention oscillates at frequencies of 14Hz to 5Hz down to achieve the sleep state, and from 5Hz to 14Hz upward to increase the ability to concentrate.

For this 1 page drawing Application of the invention The invention relates to a device for electromagnetic interference of the brain wave pattern against sleep disorders; the device is designed as a transportable cushion and is therefore in any place, eg. B. in the clinic, at home, on vacation u. Ä. Can be used. Characteristic of the known technical solutions Apparatus for inducing and generating specific brain wave patterns are known (DE-OS 3100400, A61M 21/00); The generated waves have a frequency between 14Hz and 5Hz, which correspond to the brainwave pattern in the transition from the awake to the sleep state (a-waves). The well-known external influence of the brain wave pattern, which can be recorded in the electroencephalogram for each activity state of the cerebral cortex, has the disadvantage that a disturbing factor emanates from the light or sound itself, which under certain circumstances causes a prevention of sleep. Object of the invention The object of the invention is to provide a simple, portable device for completely undisturbed, global electromagnetic interference of the higher brain centers (cortex, thalamus, reticular system). Explanation of the essence of the invention The invention has for its object to provide a device that generates an alternating electromagnetic field, whereby the possibility of arbitrary influence on the activity state of the cerebral cortex is given and is easy to handle by the sleep disturbed. According to the invention the object is achieved in that an electromagnetic alternating field is generated by means of a generator. The generator is changed in frequency by a sawtooth generator from 14Hz to 5Hz down. Rectangular pulses occur whose frequency corresponds to the a-wave pattern in the transition from the awake state to the sleep state. The sawtooth generator additionally causes a decrease in amplitude via a modulator. Provided coils, which are incorporated vertically into a head pad such that the largest field strength exists on-head in the amount of brain cores are fed via a power amplifier. By means of a sawtooth generator, the device is switched off when the lower frequency limit (5 Hz) is reached via a timer. The advantage of the invention is that the electromagnetic field is not perceived by the subject and a sufficient but harmless field strength is achieved by focusing. Further, it is possible to use the device according to the invention in reverse functional sequence (5Hz to 14Hz) to increase the concentration ability of the subject. embodiment The invention will be described below with reference to an embodiment. explained in more detail. FIG. 1 shows a block diagram of the device
Figure 2: a design of the head pad According to FIG. 1, an astable multivibrator 61) generates a square-wave voltage whose frequency is changed by the sawtooth generator (2) from 14 Hz to 5 Hz or vice versa. The signal obtained in a modulator, also by the sawtooth generator (2), in its amplitude changed, namely in the functional state - falling asleep - decreasing, and in the functional state - increasing the ability to concentrate - reinforcing. The signal obtained is used by the power amplifier (4) to power the two coils (5). The coils (5) are helically wound on the support plate (8) by a respective Magneteisenkem (6). The magnetic iron cores (6) are connected by the magnetic iron plate (7), which also conducts the field lines below the coils (5). The magnetic iron cores (6) are glued in the support plate (8). The coils (5) are connected in series; the terminals (9) are connected to the output of the power amplifier (4). The coil complex (5, 6,7,8) is embedded in a pillow pad (10) for the support of the head (11) (Figure 2). The mode of operation of the device can be described as follows: The origin of the brain waves in the electroencephalogram lies in the pyramidal cells. They enforce vertically well-ordered the entire cerebral cortex. They act like many small dipoles and generate an electromagnetic alternating field when excited, which can be demonstrated on the scalp with the electroencephalograph. The cause is very short potential differences between different sections of the pyramidal cells. These act as elementary generators for the wave activities in the electroencephalogram.
