Method and medical monitoring device or cognitive in real time by analyzing the cerebral electromagnetic activity of an individual, applying the method to characterize and differentiate physiological or pathological states

The method captures and digitizes electrophysiological signals (10) and calculates the synchronization between all the frequency pairs in each band of frequencies between 0-2000 Hz (11). A data base is established (12) and the period studied is statistically validated (13). Cognitive or specific pathological periods are detected (14) and a warning signal (15) may be initiated Independent claims are also included for the following: (1) application of the method to a cognitive study in real time; and (2) equipment for medical or cognitive study in real time of electromagnetic brain activity including means for data capture, digitization, calculation of synchronization, statistical validation, detection of cognitive periods and initiation of warning.
