By means of autoradiographic and ablation-degeneration techniques, the intrinsic cortical connections of the posterior parietal cortex in the rhesus monkey were traced and correlated with a reappraisal of cerebral architectonics. Two major rostral-to-caudal connectional sequences exist. One begins in the dorsal postcentral gyrus (area 2) and proceeds, through architectonic divisions of the superior parietal lobule (areas PE and PEc), to a cortical region on the medial surface of the parietal lobe (area PGm). This area has architectonic features similar to those of the caudal inferior parietal lobule (area PG). The second sequence begins in the ventral post/central gyrus (area 2) and passes through the rostral inferior parietal lobule (areas PG and PFG) to reach the caudal inferior parietal lobule (area PG). Both the superior parietal lobule and the rostral inferior parietal lobule also send projections to various other zones located in the parietal opercular region, the intraparietal sulcus, and the caudalmost portion of the cingulate sulcus. Areas PGm and PG, on the other hand, project to each other, to the cingulate region, to the caudalmost portion of the superior temporal gyrus, and to the upper bank of the superior temporal sulcus. Finally, a reciprocal sequence of connections, directed from caudal to rostral, links together many of the above-mentioned parietal zones. With regard to the laminar pattern of termination, the rostral-to-caudal connections are primarily distributed in the form of cortical "columns" while the caudal-to-rostral connections are found mainly over the first cortical cell layer.
通过放射自显影和切除-变性技术，对恒河猴后顶叶皮质的内在皮质连接进行了追踪，并与对大脑结构学的重新评估相关联。存在两个主要的从前到后的连接序列。一个序列始于中央后回背侧（2区），并通过顶上小叶的结构分区（PE区和PEc区），延伸至顶叶内侧面的一个皮质区域（PGm区）。该区域具有与尾侧下顶叶（PG区）相似的结构特征。第二个序列始于中央后回腹侧（2区），穿过嘴侧下顶叶（PG区和PFG区），到达尾侧下顶叶（PG区）。顶上小叶和嘴侧下顶叶也向位于顶叶岛盖区、顶内沟和扣带沟最尾端部分的其他各个区域发出投射。另一方面，PGm区和PG区相互投射，投射至扣带区、颞上回最尾端部分以及颞上沟的上缘。最后，一个从尾到嘴的相互连接序列将上述许多顶叶区域连接在一起。关于终末的分层模式，从前到后的连接主要以皮质“柱”的形式分布，而从尾到嘴的连接主要见于第一皮质细胞层。
