As shown in fig. 1, the apparatus includes:
the global detection module 01 is used for acquiring global signal cooperativity of a plurality of brain areas of a target user, wherein the global signal cooperativity is calculated based on first brain wave data acquired by each brain area.
In particular, the target user may be any user who has a need for using a brain stimulation device, such as a user who needs to use a transcranial alternating current stimulation device. In this embodiment, a plurality of brain wave acquisition units are provided in the brain stimulation apparatus in advance, each brain wave acquisition unit corresponds to a different brain region of the target user, and each brain wave acquisition unit is used for acquiring brain wave data of one brain region. In an actual application scene, when a target user starts a brain stimulation instrument, the brain stimulation instrument starts each brain wave acquisition unit first to acquire first brain wave data of each brain region. And then, calculating the global signal cooperativity of each brain region by analyzing the signal waveform cooperativity of each first brain wave data. It will be appreciated that there are differences in brain states for different users or groups of users, and that brain wave data for different brain regions may reflect the brain state differences, resulting in different numerical characteristics for global signal cooperativity for different users or groups of users. The better the brain state, the stronger its global signal cooperativity, and conversely the weaker.
In one implementation, the global detection module 01 includes:
the brain region comparison unit is used for calculating signal cooperativity between every two brain regions according to the first brain wave data;
and the cooperativity calculation unit is used for calculating the global signal cooperativity according to each signal cooperativity.
Specifically, after the first brain wave data of each brain region is acquired, the first brain wave data are combined two by two, and signal cooperativity is calculated. For example, first brain wave data a, b, c corresponding to the brain regions A, B, C are currently acquired. Calculation of Signal cooperativity X of a and b 1 Signal cooperativity X of a and c 2 Calculating the signal cooperativity X of b and c 3 Then calculate X 1 、X 2 、X 3 Global signal cooperativity of brain region A, B, C is determined from the average value. The signal cooperativity can reflect the communication state between two brain regions, so that the communication state of the whole brain can be analyzed from the global situation through the signal cooperativity between every two brain regions, and the global signal cooperativity can be calculated.
In one implementation, the method of calculating the signal cooperativity between two of the brain regions includes:
calculating the phase-amplitude coupling degree between the two first brain wave data according to the first brain wave data of the two brain regions;
and calculating the signal cooperativity of the two first brain wave data according to the phase-amplitude coupling degree.
In particular, the signal cooperativity between the two first brain wave data is evaluated by the phase-amplitude coupling condition. Taking two brain areas of the temporal lobe and the frontal lobe as an example, acquiring first brain wave data corresponding to the temporal lobe and the frontal lobe respectively, and detecting the phases of the two first brain wave data, wherein the amplitude of a high-frequency wave band (gamma wave band) of the temporal lobe of the young is consistent with the phase of an alpha wave band of the frontal lobe, and the phase-amplitude coupling degree is high, so that the signal cooperativity is strong; the elderly suffer from weak signal cooperativity due to low phase-amplitude coupling degree caused by nerve fracture and the like.
As shown in fig. 1, the apparatus further includes:
and the global judging module 02 is used for judging whether the brain stimulation is carried out on the target user according to the global signal cooperativity.
Specifically, the value of global signal cooperativity can reflect the current overall brain state of the target user, so as to judge whether the target user needs to optimize the brain state through brain stimulation.
In one implementation, the global determination module 02 includes:
the threshold determining unit is used for acquiring the user information of the target user and determining a synergy threshold according to the user information;
the execution judging unit is used for performing brain stimulation if the global signal cooperativity is smaller than the cooperativity threshold value; if the global signal synergy is greater than or equal to the synergy threshold, no brain stimulation is performed.
Specifically, the synergy threshold is a decision boundary that divides whether or not brain stimulation is performed, and since different users have individual differences, the present embodiment sets an appropriate synergy threshold specifically for the target user according to his or her user information. For example, the user information may include the age of the user, and the nerve break condition may become more severe with age, so that the nerve connection state of the young person is better than that of the old person, so that the older the user, the lower the synergy threshold. In an actual application scene, if the global signal cooperativity calculated by the target user at present is smaller than the cooperativity threshold value corresponding to the target user, the current brain state of the target user is required to be optimized through brain stimulation; if the global signal cooperativity calculated by the target user is greater than or equal to the cooperativity threshold value corresponding to the target user, the current brain state of the target user is indicated to be unnecessary to be optimized temporarily, and a brain stimulation instrument can be omitted.
As shown in fig. 1, the apparatus further includes:
the local detection module 03 is configured to obtain local signal synchronicity corresponding to each brain region if brain stimulation is performed, where the local signal synchronicity of each brain region is calculated based on second brain wave data acquired at a plurality of sites in the brain region.
Specifically, in this embodiment, a plurality of sites are provided in advance in each brain region, and each site is provided with a brain wave acquisition unit. For example, for each brain region, a brain wave acquisition unit is arranged at the central position of the brain region and is used for acquiring first brain wave data; and a plurality of brain wave acquisition units are circumferentially arranged around the central position of the brain region at preset distances and are used for acquiring second brain wave data. In an actual application scene, if a target user needs to optimize the brain state through brain stimulation at present, starting a brain wave acquisition unit of each site in each brain region to acquire a plurality of second brain wave data, and calculating signal synchronism by analyzing signal waveforms of the second brain wave data to acquire local signal synchronism of the brain region. Generally, the more normal a local state of a brain region is, the higher the synchronism of brain wave data acquired at different points of the brain region, i.e. the higher the local signal synchronism is, and vice versa.
In one implementation, the local detection module 03 includes:

and the synchronicity calculating unit is used for determining the synchronicity of the local signals according to the oscillation similarity.
Specifically, local signal synchronicity refers to the degree of similarity of brain wave data acquired at different points in the same brain region. The activity of the cerebral cortex is supported by various oscillations generated by the brain, and under normal conditions, waveform oscillations of a plurality of second brain wave data acquired by the same brain region have self-similarity, that is, oscillation characteristics are similar. The present embodiment calculates the oscillation similarity from the oscillation characteristic data of each second brain wave data. The higher the oscillation similarity, the stronger the local signal synchronicity in the brain region, and conversely the weaker.
In another implementation manner, the calculating the oscillation similarity of each of the second brain wave data according to each of the oscillation characteristic data includes:
judging whether the two oscillation characteristic data have phase locked oscillation behaviors or not according to the two oscillation characteristic data;
if the first numerical value exists, the first numerical value is used as the oscillation similarity of the corresponding second brain wave data;
if the first brain wave data does not exist, the second numerical value is used as the oscillation similarity of the corresponding second brain wave data, wherein the first numerical value is higher than the second numerical value;
and taking the average value of the oscillation similarity between every two second brain wave data as the oscillation similarity of the whole second brain wave data.
Specifically, the signal synchronism of the present embodiment is mainly to determine phase synchronization, that is, whether or not there is oscillation behavior of phase lock between two brain wave data. And judging whether the phases are synchronous or not by pairing the oscillation characteristic data, obtaining the oscillation similarity between the second brain wave data, and obtaining the overall oscillation similarity of all the second brain wave data by means of average value calculation.
As shown in fig. 1, the apparatus further includes:
and the brain region screening module 04 is used for synchronously screening out target brain regions to be stimulated according to the local signals of the brain regions, and regulating and controlling brain stimulation instruments used by the target users according to the target brain regions.
Specifically, the brain state of each brain region can be evaluated by the local signal synchronicity of the brain region, and the more normal the brain state of the brain region is, the higher the synchronicity of brain wave data acquired by different points of the brain region is, namely, the higher the local signal synchronicity is. Thus, the target brain region needing electric stimulation can be screened out by comparing the local signal synchronicity of each brain region. And accurately regulate and control the brain stimulation instrument according to the position and the category of the target brain region.
In one implementation, the brain region screening module 04 includes:
and the synchronicity comparison unit is used for determining the target brain region according to the brain region with the minimum synchronicity of the local signals.
Specifically, the local signal synchronicity may reflect the local brain state of the brain region, so the lower the local signal synchronicity, the higher the optimization requirement of the brain region is, and in this embodiment, the brain region with the lowest local signal synchronicity is selected for electrical stimulation by using the brain stimulation apparatus each time.
In one implementation, the brain region screening module 04 further includes:
the parameter determining unit is used for determining a stimulation parameter combination according to the target brain region and regulating and controlling the brain stimulation instrument according to the stimulation parameter combination;

if brain stimulation is carried out, continuing to execute the step of acquiring the synchronicity of local signals corresponding to each brain region;
and if the brain stimulation is not performed, controlling the brain stimulation instrument to stop running.
Specifically, the stimulation parameter combinations applicable to different brain regions are different, and the embodiment can preset the stimulation parameter combinations corresponding to different brain regions. In an actual application scene, corresponding stimulation parameter combinations are determined according to a target brain region, and a brain stimulation instrument is regulated and controlled to operate based on the stimulation parameter combinations. And after the preset time period, re-detecting the overall brain state of the target user to judge whether the brain stimulation is needed to be continued. If the brain stimulation is still needed to be continued, the brain state of the brain regions optimized by the brain stimulation instrument may be improved, so that the local signal synchronicity of each brain region needs to be re-acquired to determine the target brain region to be stimulated; if brain stimulation is not needed, the brain stimulation instrument is closed timely, and excessive stimulation to a target user is avoided.
In one implementation, the determining a stimulation parameter combination from the target brain region includes:
constructing a first stimulation waveform for optimizing the synchronism of local signals according to the second brain wave data corresponding to the target brain region;

a combination of stimulation parameters for the target brain region is determined based on the first stimulation waveform, the second stimulation waveform, and the stimulation intensity.
Specifically, the stimulus parameter combination of the present embodiment is mainly determined by the stimulus waveform and the stimulus intensity. For the stimulus waveforms, the embodiment adopts a combination optimization form, and two stimulus waveforms are constructed to optimize global signal synergy and local signal synchronism respectively. The method is characterized in that the method is used for optimizing the synchronism of local signals and is a first stimulation waveform, and the optimization target of the first stimulation waveform is to improve the similarity of brain wave data acquired respectively by different points of the same brain region, so that the first stimulation waveform is constructed by analyzing second brain wave data acquired by different points of the target brain region; the second stimulation waveform is used for optimizing the local signal synchronism, and the second stimulation waveform is constructed by analyzing the phase-amplitude coupling difference between the first brain wave data of the target brain region and the other brain regions because the second stimulation waveform is optimized to improve the phase-amplitude coupling degree of the brain wave data acquired by the target brain region and the other brain regions respectively.
