SEEG signal processing methods in the application of epilepsy recognition

The invasive brain-computer interface uses large-scale sampling to directly record intracranial electrophysiology by implanting electrode arrays into the brain. It is widely used to treat mental illnesses such as epilepsy, Alzheimer's disease, and stroke. In recent years, there has been an increase in research on analyzing SEEG signals and obtaining brain mental illness. Commonly used analysis methods include quantifying high-frequency oscillations or functional connectivity changes. This article reviewed the main technical methods and related applications of the invasive brain-computer interface in the treatment of epilepsy. In addition, this article also summarized the advantages and future development of SEEG in the treatment of epilepsy.
