The dynamics of phase synchronization of evoked by sound cortex potentials was investigated for normal patients and persons slightly irradiated during Chernobyl crash. Phases of signals were calculated at points of wavelet spectrograms ridges. The difference of phase dynamics of these normal and patients groups was found. The difference is the quantity of channels working synchronously. Normal people show less number of channels working synchronously except of patients. It may be explained by destruction of the brain regional specification of EEG reaction of sound test.
