Research progress on changes in EEG time-frequency signals in patients with chronic pain
Chronic pain is a subjective experience that is difficult to accurately and objectively assess.Electroencephalography(EEG)can record physiological electrical signals generated during brain activity,and time signals reflect brain activity during task processing.The frequency signals reflect quiet brain activity.This paper reviews changes of event-related potential in EEG time signal,changes of different frequency bands in frequency signal and changes of event-related synchronization or desynchronization between the two signals in patients with chronic pain.
