Video EEG technology is adopted, that is, EEG technology is combined with camera technology. While doing EEG, video is recorded, and the EEG and video images at each moment are set up one by one through software. In this way, we can watch the synchronous video recording of patients' epileptic seizures while studying EEG, which greatly improves the understanding of epileptic seizures, and can also easily scrape off the interference of false errors and exclude non-epileptic seizures.
