Methode originale d'estimation des potentiels evoques moyens: Application a l'audiometrie electroencephlographique

Abstract

We expound in this paper a method of estimation of a signal which is periodically superimposed on EEG activity. We use the statistical properties of the vertex EEG obtained with the stability which is necessary for audiometric analysis: the conditional mean versus the correlation coefficient is a straight line. The method needs fewer stimuli than classical summation. We have applied this technique to auditory evoked potentials, doing a detection and a pattern analysis.
