Afferent cortical connections and architectonics of the superior temporal sulcus and surrounding cortex in the rhesus monkey.

Abstract

A cyto- and myeloarchitectonic parcellation of the superior temporal sulcus and surrounding cortex in the rhesus monkey has been correlated with the pattern of afferent cortical connections from ipsilateral temporal, parietal and occipital lobes, studied by both silver impregnation and autoradiographic techniques. The results suggest a definite organization of this region. Subdivisions of the superior temporal gyrus are tied together in a precise sequence of connections beginning in primary auditory cortex. The inferotemporal area, which receives input from the lateral peristriate region, can also be divided into architectonic divisions, each of which is related to the others in a specific pattern of connections. Within the superior temporal sulcus several distinct areas exist. In the caudal reaches is found a region that receives input from both primary visual and visual association cortices. This zone is similar to the Clare-Bishop area of the cat. Other superior temporal sulcus zones receive input primarily from one limited area of association cortex. A strip in the upper bank receives input exclusively from the superior temporal gyrus. An area in the rostral lower bank has afferent connections mainly with the inferotemporal area, and a zone in the depth of the superior temporal sulcus receives fibers from a region within the lower bank of the intraparietal sulcus. Two additional zones, in the upper bank of the superior temporal sulcus, however, have multiple sources of cortical input: the peristriate belt, inferior parietal lobule and caudal superior temporal gyrus.
