The middle temporal gyrus and inferior temporal gyrus are involved in a number of cognitive processes, including semantic memory processing, language processes (middle temporal gyrus), visual perception (inferior temporal gyrus), and integrating information from different senses. The inferior temporal gyrus in the monkey appears to be unique among the many extrastriate visual cortices in its importance for normal performance of delayed match-to-sample, a visual memory task. Superior temporal gyrus: the auditory area is present mostly in the floor of the lateral sulcus (in the anterior transverse temporal gyrus). Figure 1.
