[0002] Electrically guided treatment of epilepsy refers to the use of guiding electrodes made of highly conductive materials and circuit control systems to guide the high voltage (1000-3000uV) generated by local epileptic discharges in the brain to the extracranial area with lower voltage (<100uV), thereby reducing the high voltage of epileptic discharges and avoiding the spread of epileptic discharges, thereby preventing and alleviating the occurrence of clinical symptoms of epilepsy.

[0003] Traditional electrical guidance methods and devices have the function of conducting neural electrophysiological signals out of the body, which is convenient for studying the relationship between current conduction intensity and treatment effect, and preventing and alleviating the occurrence of clinical symptoms of epilepsy. There are several prominent problems: First, the traditional method of adjusting the guidance current by regulating the resistance of the guidance electrode has unsatisfactory actual effect; second, the traditional method of electrical guidance by manual intervention has not formed a closed-loop control method that relies on automatic electrical guidance and intelligent identification by sensors, which is inconvenient and untimely to operate, and the control effect is unsatisfactory; third, electrophysiological signals rely on manual collection, data acquisition is poor in real time, the amount of data is small, and the recording and analysis are cumbersome, which is not conducive to the continuous and in-depth development of epilepsy treatment research; fourth, the traditional method uses the bioelectricity of the scalp surface as the low potential.
