Cognitive processes in disorders of consciousness as revealed by EEG time–frequency analyses

Highlights ► Oscillatory analyses are suggested for testing cognition in patients with disorders of consciousness. ► Time–frequency analysis examines cognitive processes reflected by different oscillations. ► Actively counting a name induces strong event-related synchronization of theta oscillations...
