The present study examined whether resting EEG power and coherence abnormalities in BP are distinct from those in SZ. Beta and gamma power were increased in BP relative to SZ (which may be associated with mania symptoms), as well as higher intra-hemispheric coherence at beta. In contrast, SZ exhibited a general increase in coherence at delta within hemispheres, and theta across hemispheres compared to BP. They also showed greater intra- and inter-hemispheric coherence relative to NC at alpha. Together, the distinct patterns of resting EEG abnormalities in these two clinical populations suggest the potential for EEG to differentiate between the neurophysiological processes affected by the two disorders.
