“…This response at 170 ms is not influenced by the familiarity of the face (Bentin et al, 1996;Bentin & Deouell, 2000;Eimer, 2000a), thus presumably corresponding to bottom-up aspects of perceptual processing (akin to early structural encoding in the model by Bruce & Young, 1986). Postperceptual processing of faces, such as recognition of identity, relies on anterior temporal cortices and occurs with latencies in excess of 200 ms (Seeck et al, 1993). Later activity in occipital regions that discriminates between different emotions is also seen after 500 ms and is influenced by the particular task, presumably reflecting top-down modulation (Krolak-Salmon, Fischer, Vighetto, & Mauguiere, 2001).…”

Recognizing emotion from facial expressions draws on diverse psychological processes implemented in a large, and functional magnetic resonance imaging (fMRI). The sheer diversity of findings precludes any simple summary and argues against the isolation of only a few structures. Instead, it is becoming clear that recognizing facial emotion draws on multiple strategies subserved by a large array of different brain structures. This review will focus on those processes and structures whose role we understand best at present and will focus primarily on data from functional imaging and lesion studies. The review will not cover details of face identity processing or of facial emotion processing in psychiatric disorders.

Face perception and recognition is an intriguing ability, already present in neonates. Numerous studies in patients with brain lesions identified the temporo-occipital cortex as the crucial structure for this capacity. Analysis of electrical signals (EEG) inside the brain of patients implanted with intracranial electrodes for diagnostic purposes allows researchers to describe the temporal and spatial organization of responses to various aspects of face processing in human subjects. Several findings have emerged and appear relevant for cerebral organization in general: (1) Selective face responses were obtained from the basal temporo-occipital cortex at around 200 ms (N200); however, other structures such as the lateral temporal lobe and frontal cortex also participate in face recognition and perception tasks. (2) Each structure has a distinct "response profile"; that is, with respect to a given task certain structures respond strongly, others less or not at all. This profile might change with a different task, although the physical parameters of the stimuli remain the same. (3) The right hemispheric predominance of face processing, as suggested by patient data and studies in healthy volunteers, seemed to be restricted to its early stages (i.e., before 100 -150 ms). (4) Recognition of faces might be associated with differential intracranial responses, despite an incorrect overt response, reflecting neurophysiological correlates of implicit memory. (5) The more the stimulus resembled a complete human face, the earlier and larger the N200 response was found, in particular over the basal temporobasal cortex. Analysis of electrical signals from intracranial electrodes might help to improve our understanding of the underlying physiological and anatomical constraints of cognitive processes.

“…The intracranial recordings from the face-specific sites [10] did not show significant differences for components P150, N200, P290, P350, or N700 between famous and nonfamiliar faces. On the other hand, intracranial recordings by the other authors [11] showed differential responses, mainly from the right amygdala, starting from about 150 ms. The purpose of the current study was to determine the timing and possible scalp locations for the differences in face processing related to face familiarity.…”
