结合放射自显影和辣根过氧化物酶组织化学被用来确定端脑结构连接的感觉和运动组件的三叉神经系统的鸽子。一个直接的端脑投射从三叉神经感觉主核的基底核通过五额叶束被证实。基底核投射到覆盖的新纹状体内的神经元带上。该区域（新纹状体额部，三叉神经部：NFT）产生额-原纹状体束，其终止于中间原纹状体和位于脑室内侧的上覆新纹状体尾部（新纹状体尾部，三叉神经部：NCT）。反过来，NCT投射到含有枕-中脑束细胞体的中间原纹状体区域。该通路提供了端脑和下脑干外侧（小细胞）网状结构内的运动前区之间的联系。在这些实验中定义的三叉神经感觉运动回路已经被神经行为学研究牵连在鸽子的啄、抓和喂食的控制中。
A combination of autoradiography and horseradish peroxidase histochemistry was used to identify telencephalic structures linking the sensory and motor components of the trigeminal system in the pigeon. A direct telencephalic projection from the principal trigeminal sensory nucleus upon the nucleus basalis via the quintofrontal tract was confirmed. Nucleus basalis projects upon a belt of neurons within the overlying neostriatum. This region (neostriatum frontale, pars trigeminale: NFT) gives rise to the fronto‐archistriate tract which terminates both in the archistriatum intermedium and in the overlying neostriatum caudale, medial to the ventricle (neostriatum caudale, pars trigeminale: NCT). NCT projects, in turn, upon a region of archistriatum intermedium containing cell bodies of the occipito‐mesencephalic tract. This pathway provides a link between the telencephalon and premotor areas within the lateral (parvicellular) reticular formation of the lower brainstem. The trigeminal sensorimotor circuit defined in these experiments has been implicated by neurobehavioral studies in the control of pecking, grasping, and feeding in the pigeon.
