Simultaneous bicoherence analysis of occipital and frontal electroencephalograms in awake and anesthetized subjects

Highlights • A prominent α rhythm accompanying high bicoherence growth is often seen in occipital awake EEGs in younger persons. • With the induction of anesthesia, the occipital α bicoherence peak disappears and a frontal α bicoherence peak appears. • The occipital neural network is spatially diffe...
