Phase-shift analysis on single-trial EEG signals and its correlation with behavior in a visual perceptual task

摘要

Neural synchrony, measured as phase synchronization of electroencephalogram (EEG) signals, have been studied in relation with different cognitive task. However, not as much is known about how phase-shift relates to this process. Here we propose a method to detect phase-shift on single-trial EEG signals and assess its correlation with subjects' behavior. As preliminary result, this methodology was successfully applied in EEG recorded from three subjects during a bi-stable visual perceptual task.
