A novel EEG setup for online phase detection

Introduction: Local phase information of oscillatory activity has been shown to reflect different states of brain activity and is thought to play a crucial part in human brain information processing. In the visual system, phase properties of parieto-occipital alpha band oscillations were associated with perception and perception thresholds respectively. Along these lines, occipital TMS-induced phosphene-probability was related to the ongoing occipital alpha phase. Purpose: Though phase information is thought to play an important role in signal processing in the human brain, there is few data addressing 'online'…
