Abstract

OBJECTIVE: Temporale lobe and occipito-temporal cortical areas play an important role in facial emotion perception (FEP). FEP might be represented by event-related brain oscillations. In patients with temporal lobe epilepsy (TLE), impairment of FEP was shown with behavioral and functional neuroimaging (FMRI, PET, MEG) but not event-related oscillations, which is a well known method for cognitive research studies. The present study aims to explore FEP by analyzing EEG event-related theta oscillations in patients with TLE.
