Abstract

Neurophysiological evidence showing that some neurons in the macaque inferior temporal visual cortex and cortex in the superior temporal sulcus have responses that are invariant with respect to the position, size, and in some cases view of faces, and that these neurons show rapid processing and rapid learning. This chapter provides a whole area of research which show how taste, olfactory, visual, and somatosensory reward is decoded and represented in the orbitofrontal cortex and has led to a theory of emotion, of how and why the brain implements emotion, of some emotional disorders produced by brain damage, of the reward systems involved in appetite control, and of the brain mechanisms of decision-making. The responses of these neurons reflect solution of some of the major problems of visual perception.
