Embodiment Construction

[0017] The present invention will be further described below in combination with specific embodiments.

[0018] An intervention method for transcranial alternating current stimulation, specifically comprising the following steps:

[0019] (1) The electrical activity of the right frontal lobe and temporal lobe of the brain will be recorded by an electroencephalogram (EEG). The recording electrodes are placed on the scalp of the frontal lobe and temporal lobe of the individual's right brain to find the individual alpha band The frequency corresponding to the maximum amplitude wave; the specific operation method is: the alpha band brain waves (8-13 Hz) of the right frontal lobe and temporal lobe of the brain are collected with an increase of 0.1 Hz, and the phase locking value of the two brain regions is calculated , that is, which band has the highest synchronization between the two brain regions, and its correlation coefficient is the largest, and the frequency band with the la...

Abstract

The invention discloses an intervention method for transcranial alternating current stimulation. The method specifically comprises the following steps of (1) recording the electrical activities of a frontal lobe and temporal lobe on the right side of the brain through an electroencephalogram recorder, and placing a recording electrode at scalp of the frontal lobe and the temporal lobe of the rightbrain of an individual for searching the frequency corresponding to the maximum amplitude wave of an alpha waveband of the individual; and (2) simultaneously stimulating the frontal lobe region and the temporal lobe region of the right brain by using recorded alternating current waveforms with the same frequency through transcranial alternating current stimulation, so that the electrical activities of the two brain regions in the alpha wavebands are synchronized. The method has the beneficial effects that the condition of brain interval synchronism disorder of brain sub-health people is improved by enhancing the synchronism between specific regions of the brain network, so that the functions of improving anxiety, depressive emotion and frontal lobe related cognitive competence are achieved.

Description

technical field [0001] The invention relates to the technical field related to transcranial electrical stimulation, in particular to an intervention method for transcranial alternating current stimulation. Background technique [0002] Transcranial electrical stimulation technology transmits low-intensity current (1-2 mA) to the brain through the conductive patch on the surface of the skull to increase or decrease the excitability of neurons to regulate the activity of brain regions. [0003] Transcranial alternating current stimulation (tACS) is a classic method of transcranial electrical stimulation, which regulates the excitation threshold of neurons in specific brain regions through the stimulation of variable frequency current, so as to achieve the purpose of changing the oscillation rhythm of cortical neurons. The oscillation rhythm of the cerebral cortex can generally be divided into five bands, namely δ (1-3 Hz), θ (4-7 Hz), α (8-13 Hz), β (14-30 Hz) and γ (>30 Hz...
