EEG co-frequency detection method, EEG co-frequency stimulation method and device

Abstract

The invention relates to an electrocerebral co-frequency detection method, an electrocerebral co-frequency stimulation method and an electrocerebral co-frequency stimulation device. The electrocerebral co-frequency detection method is capable of counting brainwave co-frequency coefficients in accordance with detected electrocerebral data so that different frequency domains of brainwaves can be timely founded out. The electrocerebral co-frequency stimulation method helps to fulfill the purpose of safe electrocerebral co-frequency by means of visual and audio simulations, eye movement and auxiliary microelectric current simulation and is combined with the electrocerebral co-frequency detection method for carrying out cerebral fixed-point co-frequency electrical stimulation. By efficiently and reliably inducing brainwave co-frequency oscillation, normal sleep is induced. The electrocerebral co-frequency stimulation device is capable of inducting sleep by means of normal physiological stimulation and eye movement under real-time adjustments of electrocerebral signals. Specifically, sleep is induced based on eye movement (rapid jumping and uniform tracking movement) in combination with synchronous same-frequency audio stimulation. A patient suffering from severe insomnia and have difficulties in induction of visual and audio stimulation can be matched with fixed-point micro-electrical stimulation to achieve whole-brain slow-wave oscillation; and the function of rapidly and safely inducting sleep is fulfilled.

Description

technical field [0001] The present invention relates to EEG co-frequency technology, in particular to an EEG co-frequency detection method, an EEG co-frequency stimulation method and a device based on the EEG co-frequency detection method. Background technique [0002] In recent years, the fast-paced, high-stress, and noisy urban life has made it difficult for more and more people to fall asleep and become insomniacs. A survey in the United States in 2002 found that the incidence of insomnia among adults was 58%. The results of recent surveys in my country show that the incidence of insomnia in adults is roughly the same as that in the United States. Insomnia seriously tortures the physical and mental health of patients. Long-term insomnia is often accompanied by other serious psychological and mental disorders, which affects the quality of life and work of patients, and even causes patients to commit suicide at the cost of getting rid of the pain of insomnia.

Problems solved by technology

[0013] Then, according to statistics, due to individual differences, the frequency of EEG synchronous slow waves during sleep is different for each individual, roughly in line with the normal distribution within the interval of 7HZ-15HZ, of which 1OHZ is the highest; according to the test, the human brain during sleep The slow wave frequency band changes with time, and the slow wave frequency bands corresponding to different brain regions are different. D1-D3 only use simple stimulation, and no visual stimulation and eye movement stimulation are recorded; due to auditory nerve brain region stimulation The coverage is small, and it cannot cause the slow wave synchronization of the whole brain, and the simple music has no rhythm, and cannot be adjusted in time according to changes in the brain wave, and the effect is very unsatisfactory.

[0014] Whether it is D1-D3 or the existing technology, there is no method for detecting the same frequency of brain waves, which makes it impossible to identify the frequency correlation degree of each region of the brain, and it is also impossible to find the key areas that cause brain waves to be difficult to have the same frequency in time. It is impossible to achieve targeted stimulation, let alone brain wave simultaneous frequency stimulation
