Research has indicated that self-related processing may be subserved by a cortical network within the right prefrontal cortex (RPFC). These indications are derived from case studies as well as functional neuroimaging data in which self-related stimuli appear to activate cortical structures within the RPFC. To extend these findings we employed self-faces as stimuli. Under two experiments, one using fMRI (functional magnetic resonance imaging) and the other employing ERPs (event-related potentials), subjects were presented with self-faces under two slightly different paradigms. Preliminary data from both fMRI and ERPs indicate that self-face perception and self-processing may involve preferential circuits within the RPFC. These data support the notion that there may be right frontal lateralization for self-related processing.
