The distribution of catecholamines within the inferior olivary complex of the gerbil and rabbit

Abstract
The inferior olivary complex of pre‐adult and adult gerbils and rabbits was examined with the histochemical fluorescence technique for the intraneuronal‐demonstration of monoamines. The observed patterns were compared directly to those seen in the rat. Dissimilar distributions of monoamine‐containing varicosities were observed between these mammalian species. These data support the belief that monoamine distribution as previously reported for the rat brain is not a complete model for other mammals. Also, a question is raised concerning the existence of the previously reported monoamine‐containing cell bodies in this nuclear complex.
