The focus of this review is the anatomy and physiology of higher cortical visual areas in macaque monkey, which are homologous to regions of the human visual cortex and numerous clinical syndromes resulting from damage to these areas.

An understanding of these areas is important, as many of these patients will seek the attention of the neurologist, ophthalmologist, even psychiatrist, poorly defined complaints that may be difficult to specifically define
