ABSTRACT
Recent evidence from neuropsychological patients with focalized lesions and functional brain imaging studies indicate that processing of self is distinguishable from processing of information about others (e.g., recognizing a familiar face). Here, we conduct an effect-location meta-analysis (Fox et al., 1998) of 9 functional neuroimaging studies of self-face recognition. The evidence provides support for a right-dominated, but largely bilaterally distributed model for self-face processing. Four areas are consistently activated: the left fusiform gyrus, bilateral middle and inferior frontal gyri, and right precuneus. The evidence is interpreted in light of a developing model of self-face recognition as part of a larger social cognitive stream of processing.

Three priming experiments were conducted to determine how information about the self from different sensory modalities/cognitive domains affects self-face recognition. Being exposed to your body odor, seeing your name, and hearing your name all facilitated self-face recognition in a reaction time task. No similar cross-modal facilitation was found among stimuli from familiar or novel individuals. The finding of a left-hand advantage for self-face recognition was replicated when no primes were presented. These data, along with other recent results suggest the brain processes/represents information about the self in highly integrated ways.
