Connections between Inferotemporal Cortex and Superior Temporal Sulcus Laboratory for Neural Architecture Dr. K.S. Saleem, and his colleagues in the Laboratory for Neural Architecture and Laboratory for Cognitive Brain Mapping have shown the differential connections of anterior inferotemporal cortex (areas TEad and TEav, respectively) with the superior temporal sulcus regions (STS) in the macaque monkey (Saleem et al., 2000). Anterior inferotemporal cortex of the macaque monkey is an extrastriate visual cortical area, which is thought to be important for object vision, i.e., discrimination and recognition of visual images of objects. A clear dichotomy in the connections of the rostral part of STS has been demonstrated in the present study: the TEad is strongly connected with the upper bank of rostral STS, whereas TEav is strongly connected with the lower bank and fundus of the rostral STS (see Figure). These results revise the classical view (in the literature) that the lower bank of rostral STS is connected with inferotemporal cortex (area TEad) whereas the upper bank of rostral STS is connected with the parietal, prefrontal and superior temporal regions. The upper bank of the rostral STS is called the superior temporal polysensory area (STP; see Figure), since it was previously found that neurons there respond to auditory, somatosensory and/or visual stimuli. The present results thus suggest that the polymodal representation in STP interacts more with information processing in TEad than TEav. The results also suggested that the information processing in the lower bank of the rostral STS is distinct from that in TEad, and the former more directly interacts with TEav than TEad. 　 magnified scene by clicking image Saleem, K.
