目前大多数解剖学文献将三叉神经感觉核和孤束核分别描述为介导躯体和内脏传入感觉冲动通路中的简单站点。三叉神经纤维被认为是纯体细胞的，仅止于三叉神经核，此外，三叉神经核还被认为接受第viii、第ix和第x脑神经的小体细胞传入成分。后一种神经的内脏传入纤维被认为终止于孤立束核，并构成该核的唯一主要感觉供应。因此，根据目前的描述，这两个核显然具有不同的功能和明确的结构。最近对三叉神经感觉核结构的观察（Olseewski, 1950; Bstrom, 1953）表明，情况可能比一般认为的更复杂，对传入脑神经纤维的一些观察也是如此。然而，我们对后一个项目的了解仍有重要的差距。基于正常材料的调查在某种程度上是相互矛盾的，到目前为止，实验研究只使用了马奇方法，这就离开了
Most current anatomical texts describe the sensory trigeminal nuclei and the nucleus of the solitary tract as simple stations in pathways mediating afferent sensory impulses of somatic and visceral origin, respectively. The trigeminal nerve fibers are considered as being purely somatic, terminating exclusively in the trigeminal nuclei, which in addition are believed to receive small somatic afferent components of the VIIth, IXth and Xth cranial nerves. The visceral afferent fibers of the latter nerves are said to terminate in the nucleus of the solitary tract and to constitute the only primary sensory supply of this nucleus. The two nuclei according to current descriptions thus apparently are functionally different and well defined structures. Recent observations on the structure of the sensory trigeminal nuclei (Olseewski, '50; Bstrom, '53) suggest that eonditions may be more complex than generally assumed, as do also some observations on the afferent cranial nerve fibers. However, there are still important gaps in our knowledge of the latter item. Investigations based on normal material are in part mutually contradictory, and experimental studies have, so far, been made with the Marchi method only, which leaves
