article i nfo This study investigated the neurocognitive mechanisms underlying the role of the eye and the mouth regions in the recognition of facial happiness, anger, and surprise. To this end, face stimuli were shown in three formats (whole face, upper half visible, and lower half visible) and behavioral categorization, computational modeling, and ERP (event-related potentials) measures were combined. N170 (150-180 ms post-stimulus; right hemisphere) and EPN (early posterior negativity; 200-300 ms; mainly, right hemisphere) were modulated byexpressionofwholefaces,butnotbyseparatehalves.Thissuggeststhatexpressionencoding(N170)andemo-
