Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a high-precision transcranial electrical stimulation device. Background technique [0002] Transcranial Direct Current Stimulation (tDCS) is a non-invasive neuromodulation technology that applies constant, low-intensity current to specific intracranial brain regions through electrodes placed on the surface of the skull to achieve the regulation of neural activity in the cerebral cortex. Purpose. tDCS has different therapeutic effects on neurological and mental diseases such as stroke, cognitive impairment, aphasia and senile dementia. [0003] The traditional transcranial electrical stimulation device adopts a stimulation method of one yin and one yang. The current diffuses in a large computer area, even in the entire brain area, and the spatial focus is poor. At the same time, there is no effective detection method before the stimulation work. , making th...
