用银浸渍技术对7只恒河猴胼胝体切片后，研究了胼胝体内半球间皮层纤维的相对位置。胼胝体不同部位的切片显示出明显不同的皮质投影模式。基于这些模式，胼胝体内纤维的地形可以总结如下：(1)胼胝体的吻侧部分将半球间纤维输送到额叶的各个分支（图5A和C）。(2)胼胝体的尾侧部分将纤维输送到顶叶、颞叶和枕叶以及眼岛区（图5B和C）。(3)胼胝体的尾侧部分，顶叶纤维比颞叶纤维占据更多的吻侧位置。(4)通向中央前盖的纤维穿过胼胝体后半部分的中线。(5)颞叶（除前列腺区外）和岛叶区的纤维占据胼胝体体的尾端。(6)脾部含有通往枕叶的半球间纤维，此外还有通往前列腺区的半球间纤维。
The relative location of the interhemispheric cortical fibers within the corpus callosum was studied after callosal section in 7 rhesus monkeys with the silver impregnation techniques. Section of different parts of the corpus callosum resulted in strikingly dissimilar cortical projection patterns. On the basis of these patterns, the topography of the intracallosal fibers can be summarized as follows:(1)The rostral half of the corpus callosum carries the interhemispheric fibers to the various subdivisions of the frontal lobe (Fig. 5A and C).(2)The caudal half of the corpus callosum carries fibers to the parietal, temporal and occipital lobes and to the insulo-opercular region (Fig. 5B and C).(3)In the caudal half of the callosum, the parietal lobe fibers occupy a more rostral location than those of the temporal lobe.(4)The fibers to the precentral opercula cross the midline in the posterior half of the corpus callosum.(5)Fibers of the temporal lobe (with the exception of the prostriate area) and the insular region occupy the caudal part of the body of the corpus callosum.(6)The splenium contains the interhemispheric fibers to the occipital lobe and, in addition, those to the prostriate area.
