title: Hemispheric lateralization of emotions: absence of electrophysiological arguments.
abstract: EEG lateralization was examined during happy and sad emotional expression in 24 subjects. Happy and sad emotional states were induced by asking subjects to mentally review previously shown film-sequences. Our results failed to replicate those of previous studies, in that they showed no frontal alpha lateralization as a function of emotion. The authors discuss the literature and suggest caution before asserting the existence of electrophysiological arguments in favor lateralization of emotions in humans.
