Abstract
A new method to estimate the phase coupling of electroencephalogram (EEG) signals in different channels is based on the calculation of difference of phase characteristics for channel signals at the ridge points (maximum magnitudes) of wavelet spectra. It is shown that the method can be used to determine phase-coupled pairs of EEG leads and distinguish such pairs from uncoupled pairs. The interchannel phase coupling of EEG is estimated for cognitive and motor tests of a normal patient and a patient with craniocerebral injury
