Tire basal part of the brain or brain stem consists of the medulla oblongata and the pons. While the bulk of the tissue consists of myelinated nerve tracts passing into the spinal cord, synaptic regions such as the olivary nucleus are also present. 

By in situ hybridization histochemistry, 5-HT5B receptors have been shown to be predominantly expressed in the habenular nuclei, hippocampal CA1 pyramidal cells and inferior olivary nucleus of the rat, and at weaker levels in the entorhinal cortex and NRD (210). The 5-HT5B receptor mRNA has recently been shown to be coexpressed with the plasma membrane 5-HT transporter in the NRD (217), strongly suggesting an autoreceptor as well as heteroreceptor role for 5-HT5B as well as 5-HT5A receptors. 

This interpretation finds support in systematic studies of responses from brainstem nuclei following successive coagulative lesion production in the auditory loci (1 7). The effect of brainstem lesions on electrical potentials recorded from the superior olivary (SO) nucleus in response to microwave pulse stimulation is shown in Figure 3. Lesions in proximal nuclei (inferior colliculus, IC and lateral lemniscus, LL) had negligible influence on the response recorded from superior olivary nucleus. The response, however, disappeared after a lesion was made in its nucleus, thus, confirming the peripheral nature of the primary site of transduction.

Fig. 201. HRP- and cholineacetyl transferase (ChAT)-labelled neurons in the vestibular complex of rabbit following an HRP injection into the left ventral paraflocculus and immunocytochemistry with an antibody against ChAT. (A) The black and stippled areas correspond to dense and less dense HRP concentrations. The solid arrows delinate borders between the flocculus, ventral and dorsal paraflocculus. (B) 1-5 are rostral-caudal brainstem sections through the left vestibular complex spaced approximately 400 fim apart. The filled circles correspond to HRP- and ChAT-labelled neurons. The open circles correspond to ChAT-labelled neurons only. The filled diamonds correspond to HRP-labelled neurons only.
