Abstract. Identical inter-channel phase coherency of electroencephalogram (EEG) signals is determined for healthy subjects during cognitive and motor tests. EEG signal phase is evaluated at the points of it wavelet-spectrogram ridge. Areas of interest of the cortex at cognitive and motor tests for group of healthy subjects are determined. Inter-channel EEG phase coherency for patients after a traumatic brain injury are represented.

Keywords: electroencephalogram, wavelet-spectrogram, ridge, phase coherency
