EEG alpha power and alpha power asymmetry in sleep and wakefulness.

Abstract Asymmetry of waking electroencephalography ~EEG! alpha power in frontal regions has been correlated with waking emotional reactivity and the emotional content of dream reports. Little is known regarding alpha asymmetry during sleep. The present study was performed to compare alpha power and alpha power asymmetry in various brain regions across states of sleep and […]
