用法尔克-希拉普组织荧光法研究了幼猫和成年猫脑干内含单胺（MA）神经元胞体的分布和形态特征。本研究表明，猫中脑内的儿茶酚胺（CA）胞体主要分布于黑质的腹内侧被盖区、腹内侧被盖区、吻线核和臂旁核。许多CA神经元也存在于脑桥被盖的背外侧部分，但也在蓝斑下核，背侧丘系核和臂旁核外侧和内侧。在延髓，一些CA神经元胞体位于舌下神经核附近，而大量的CA细胞体出现在外侧网状核和外侧旁巨细胞核的水平。另一方面，大多数5-HT胞体局限于脑干的中缝核：中缝背核、中央上级核、中缝桥核、中缝大核、中缝苍白核和中缝暗核。在锥体束和下橄榄复合体的外侧也发现了一些5-HT神经元胞体。各种相似性和差异方面的地形分布的模式MA神经元在脑干的猫相比，其他哺乳动物进行了讨论。
The distribution and morphological characteristics of monoamine (MA)‐containing neuronal somata in the brain stem of kittens and of adult cats were studied by means of the Falck‐Hillarp histofluorescence method. This investigation has shown, among other things, that in the mibrain of the cat the catecholamine (CA) perikarya are chiefly confined to the pars compacta of the substantia nigra, the ventromedial tegmental area, the nucleus linearis rostralis and the nucleus parabrachialis pigmentosus. Numerous CA neurons are also present in the dorsolateral part of the pontine tegmentum but also within the nucleus subcoeruleus, in nuclei lemnisci lateralis dorsalis and in nuclei parabrachialis lateralis and medialis. In the medulla, a few CA neuronal somata are lying near the hypoglossal nucleus whereas a larger number of CA cell bodies occur at the level of nucleus reticularis lateralis and in nucleus paragigantocellularis lateralis. On the other hand, most of the serotonin (5‐HT) perikarya are confined to the raphe nuclei of the brain stem: nuclei raphe dorsalis, centralis superior, raphe pontis, raphe magnus, raphe pallidus and raphe obscurus. Some 5‐HT neuronal somata are also found lateral to the pyramidal tract and to the inferior olivary complex. The various similarities and differences in respect to the pattern of the topographical distribution of MA neurons in the brain stem of the cat as compared to that of other mammals are discussed.
