The projections to the frontal cortex from the various subdivisions of the posterior parietal region in the rhesus monkey were studied by means of autoradiographic technique. The rostral superior parietal lobule (area PE) projects to the dorsal areas 4 and 6 on the lateral surface of the frontal lobe as well as to the supplementary motor area (MII) on its medial surface. The caudal area PE sends its connections to dorsal area 6 and MII. The projections from the medial parietal cortex (areas PEc and PGm) are similar to those of the superior parietal lobule but they tend to concentrate in the more rostral part of dorsal area 6, MII, and in the cingulate gyrus (area 24). The most caudal part of the medial parietal cortex also projects to area 8. The anteriormost part of the inferior parietal lobule (area PF) projects to the ventral area 6, including the caudal bank of the lower branch of the arcuate sulcus, to the ventral area 46 below the sulcus principalis, and to the frontal and pericentral opercular cortex. The middle inferior parietal lobule (areas PFG and PG) projects to the ventral part of area 46 and area 8, whilst the posteriormost inferior parietal lobule (caudal PG and area Opt) is connected with both dorsal and ventral area 46, dorsal area 8, as well as the anteriormost dorsal area 6, and the cingulate gyrus (area 24).
采用放射自显影技术研究了恒河猴后顶叶不同亚区向额叶皮质的投射。嘴侧顶上小叶（PE区）投射到额叶外侧表面的背侧4区和6区以及内侧表面的辅助运动区（MII区）。尾侧PE区将其联系投射到背侧6区和MII区。顶叶内侧皮质（PEc区和PGm区）的投射与顶上小叶的投射相似，但它们倾向于集中在背侧6区、MII区的更嘴侧部分以及扣带回（24区）。顶叶内侧皮质的最尾侧部分也投射到8区。顶下小叶最前部（PF区）投射到腹侧6区，包括弓状沟下支的尾侧缘、中央沟下方的腹侧46区以及额叶和中央周围岛盖皮质。顶下小叶中部（PFG区和PG区）投射到46区和8区的腹侧部分，而顶下小叶最后部（尾侧PG区和Opt区）与背侧和腹侧46区、背侧8区以及最前部的背侧6区和扣带回（24区）相连。
