Abstract

Recognition of face is an essential cognitive processing to communicate information directly each other. The electrophysiological data have demonstrated that the negative event-related potential (ERP) recorded at occipitotemporal leads, the N170 potential, is a very sensitive neural correlate for faces. The fusiform gyrus, located on the ventromedial surface of temporal and occipital lobes, has been demonstrated to be a key brain region for face perception. Because the face contains the emotional informations, study about face recognition includes emotional processing as well as structural processing of face. So as a essential part of social cognition, the face recognition and facial affects preception have been paid attentions by many researchers. In this article, we reviewed some important research data about face recognition and face affect perception.
