The term area paAc of Pandya refers to one of four cortical areas that border the granulous cortex core (area Kam of Pandya and area Kalt of Pandya) in the superior temporal gyrus of the macaque defined on the basis of cytomyeloarchitecture. The others are area paAlt of Pandya, area paAr of Pandya, and area proA of Pandya. The most caudal of the four, it occupies the posterior end of the temporal operculum. It differs from Kalt in that a "small fringe" of larger pyramidal cells is seen deep in the external pyramidal layer (III), cell density is not as great in the outer layers and the internal pyramidal layer (V) is not as light. Functionally the areas are regarded as auditory cortex ( Pandya-1973 ).
