Differential neuronal responses to the self and others in the extrastriate body area and the fusiform body area.
The extrastriate body area (EBA) and the fusiform body area (FBA) are selectively activated by viewing human bodies. However, the role of these functionally defined brain areas in self-other discrimination is still unresolved. Thirty-one females were presented with 16 pictures of their own body and another body in a bikini and with scrambled images while fMRI was performed. Moreover, standardized stimulus material was used in order to localize the EBA and FBA. Region-of-interest analysis showed an enhanced BOLD response to the self-images relative to the non-self-images in the right EBA and FBA. The right EBA and FBA are activated differently by viewing oneself and others and might thus play a role in visual self-other discrimination.
