Research Abstract

Cortical area TEO of the macaque has been thought to be crucial for pattern perception but not for visual memory. This idea was derived from findings of severe deficits in pattern discrimination tasks and no or only mild deficits in visual memory tasks following lesions of area TEO.An electrophysiological study mapped the visuotopic organization of area TEO and showed significant differences between the extent of newly defined area TEO and conventional lesion site of area TEO.We examined whether the new TEO are involved in pattern perception and visual memory function. We studied effects of new TEO lesions on pattern discrimination tasks (postoperative retention and postoperative acquisition of pattern discrimination tasks, and discrimination limen tests for reduced patterns) and visual memory tasks (concurrent object discrimination and delayed matching to sample tasks), and compared the results with the results of conventional TEO and gyral TEO lesions. The pattern of deficits produced by new TEO lesions was different from that by conventional TEO lesions. Deficits in pattern discrimination tasks following new TEO lesions were significantly milder than those following conventional TEO lesions. By contrast, deficits in visual memory tasks by new TEO lesions were significantly severer than those following conventional TEO lesions. Lesions of gyral TEO produced no or slight deficits in the all tasks. These findings suggested that combined lesions of area TEO and superior temporal sulcal area adjacent to area TEO, which was involved in conventional TEO lesion site and excluded from new TEO, showed synergistic effects on pattern perception. In addition, the findings also suggested the involvement of ventromedial portion to the occipito-temporal sulcus which was defined as the ventromedial part of new TEO in visual memory function.
