title: Corticocortical connections between frontal periarcuate regions and visual areas of the superior temporal sulcus and the adjoining inferior parietal lobule in the macaque monkey.
abstract: In macaque monkeys, corticocortical connections between distinct parietotemporal visual areas (areas MST-FST, DP, and 7a) and frontal periarcuate areas are studied using tritiated aminoacids and WGA-HRP. While labeling within the banks of the principal sulcus, the dorsal part of the arcuate concavity, and the banks of the upper arcuate limb were present in both 7a and MST-FST injected animals; in the latter cases, additional projections were found towards frontal regions including the dorsomedial frontal cortex and the posterior bank of the arcuate ventral limb. Our results point to widespread frontal connections of the MST-FST complex, involving both prefrontal and premotor cortical regions.
