In this investigation, the efferent cortico-cortical projections of the orbitofrontal cortex in the rhesus monkey have been investigated using silver impregnation methods. Projections from this area were observed to terminate in the rostral portions of the temporal lobe (areas TA, TE and TG) and cingulate gyrus (area 24), the insular cortex, and some dorsolateral prefrontal areas. Although these connections characterized all areas, with the exception of Walker's area 14 and Bonin and Bailey's area FL, the caudal levels of the orbitofrontal area were found to give rise to an additional projection which terminated in the entorhinal cortex and the transitional cortices bordering the rhinal sulcus. The source of this projection correlated closely with an area labeled FF by Bonin and Bailey. This connection may provide a much more direct means for the frontal lobe to influence the hippocampus than those involving the cingulate gyrus.
在本研究中，运用银浸染法对恒河猴眶额叶皮质的传出皮质-皮质投射进行了研究。观察到该区域的投射终止于颞叶的前部（TA、TE和TG区）、扣带回（24区）、岛叶皮质以及一些背外侧前额叶区域。尽管这些连接是所有区域的特征，但沃克14区以及博宁和贝利的FL区除外，眶额叶区域的尾部被发现产生了额外的投射，该投射终止于内嗅皮质以及与鼻沟相邻的过渡皮质。这种投射的来源与博宁和贝利标记为FF的区域密切相关。与涉及扣带回的连接相比，这种连接可能为额叶影响海马体提供了一种更为直接的方式。
