A novel approach to single trial visually evoked potentials (VEP) variability analysis based on a new model of post-stimulus brain electrical activity is presented.The convolution model introduced by the autor is experimentally verified by the analysis of flash stimulus effects of EEG amplitude and phase spectra.Pattern recognition in the signal phase domain is proposed for detection of any time locked transient signals.This is illustrated by an application of a clustering algorithm in two-dimensional unwrapped phase of EEG Fourier transform space for occipitally recorded VEPs in human subjects.
