The posterior limb of the rat anterior commissure (ACp) was studied in order to better define a temporal cortex in this species. Two methods were used: (1) the anterior commissure (AC) was destroyed on one side of the midline, and the resulting anterograde degeneration was traced with the Fink-Heimer stain; and (2) the corpus callosum and hippocampal commissure were severed, but the AC was left intact. [3H]-Leucine and proline were injected into one hemisphere, and the transported label was traced into the contralateral hemisphere with autoradiography. ACp was found to project to the contralateral cortex along the rhinal sulcus. The pyriform cortex received a projection along the entire length of the sulcus. There was also a distinct projection to neocortex on the lateral surface above the rhinal sulcus which appears to be analogous to the temporal cortex projection of ACp in other species. This finding of a neocortical projection of the ACp in the rat is consistent with observations that have been made on other mammals.
为了更好地界定大鼠颞叶皮质，对大鼠前连合的后肢（ACp）进行了研究。采用了两种方法：（1）在中线一侧破坏前连合（AC），并用芬克-海默染色追踪由此产生的顺行性变性；（2）切断胼胝体和海马连合，但保留AC完整。将[³H] - 亮氨酸和脯氨酸注入一侧半球，并用放射自显影术追踪转运标记至对侧半球。发现ACp沿着鼻沟投射到对侧皮质。梨状皮质在沟的全长都接受投射。在鼻沟上方外侧表面的新皮质也有明显的投射，这似乎类似于其他物种中ACp的颞叶皮质投射。大鼠ACp向新皮质投射的这一发现与在其他哺乳动物上所做的观察结果一致。
