电生理学技术已证实，除了地形组织上的差异外，大鼠丘脑上传入通路的投射与兔、猫和猴等高等哺乳动物中发现的传入通路非常相似。诱发电位的记录显示，腹基底复合体上主要有对侧投影，内侧有广泛的口鼻区域，前腿位于腹内侧，后腿和尾巴位于小侧带中。后丘脑上有一个大的双边传入通路投影，该区域位于腹基底复合体的尾部，部分与腹基底复合体共同延伸，位于内侧膝状体的内侧。该区域地形组织的唯一标志是后腿和尾巴的侧面表现。
Electrophysiological techniques have confirmed that, except for differences in topographical organization, the projection of afferent pathways upon the thalamus of the rat is very similar to that found in higher mammals such as the rabbit, cat and monkey. Recording of evoked potentials has revealed a predominantly contralateral projection upon the ventrobasal complex, with an extensive snout region medially, foreleg representation ventromedially and hindleg and tail in a small lateral strip. There is a large bilateral projection of afferent pathways on the posterior thalamus - an area caudal to and partially co-extensive with the ventrobasal complex and medial to the medial geniculate body. The only sign of topographical organization in this area is a somewhat lateral representation of hindlegs and tail.
