Abstract
Face neurons processing specifically faces have been found in the inferotemporal cortex. These neurons detected the distances between eyes and mouth or between two eyes. This suggests that there might be face specific area in the human brain. Faces convey complex information such as species, individual identity, and emotional state. Information analysis of responses of single neurons to faces has revealed that global information (human, monkey or geometrical shapes) was represented from the start of the responses and fine information (identity, expressions) was represented 50ms after the peak of global information.
