The early perceptual processing of faces rely on occipital and temporal cortices that help in constructing a detailed representation from the available configuration of facial features while the subsequent facial expression recognition depends upon structures like amygdala and orbitofrontal cortex that in turn link the perceptual representation of faces, built in the first phase, to the knowledge about emotions (Adolphs, 2002).
