通过辣根过氧化物酶 (HRP) 的逆行轴突运输，鉴定了猫下丘 (IC) 脑桥传入细胞的起源细胞。在桥脑核中注射 HRP 后，在同侧的外核和中央周围核的尾部发现了许多标记的神经元，而在中央核中发现了一些细胞。额外的神经元出现在中部和喙部的细胞核中。该组织与其他丘状下降系统的组织形成对比。投射到上橄榄复合体和耳蜗核的神经元主要位于双侧中央核。外核中标记细胞多分布于中部至喙部，尾部数量较少。由于脑桥神经元的位置与其他脑桥下降神经元的位置不同，因此脑桥系统可能与其他丘降神经元没有共同的功能特性。讨论了脑桥神经元的功能方面，并对听觉脉冲传输到小脑中段区域的途径进行了评论。
Cells of origin of the pontine afferents from the inferior colliculus (IC) of cats have been identified by means of retrograde axonal transport of horseradish peroxidase (HRP). Following injections of HRP in the pontine nuclei, many labeled neurons were found ipsilaterally in the caudal parts of the external and pericentral nuclei, while a few cells were found in the central nucleus. Additional neurons occurred in the nuclei of the middle and rostral parts. This organization contrasts with that of other collicular descending systems. Neurons projecting to the superior olivary complex and cochlear nuclei were found predominantly in the central nucleus bilaterally. In the external nucleus labeled cells tended to be distributed in the middle to rostral regions, but they were few in number in the caudal part. Since the locations of IC-pontine neurons are different from those of other IC descending neurons, the IC-pontine system probably does not share common functional properties with the other collicular descending neurons. Functional aspects of the IC-pontine neurons are discussed, with a comment on a pathway for the transmission of auditory impulses to the midvermal area of the cerebellum.
