PG - 115-20 AB - Intracerebroventricular (i.c.v.) injection of somatostatin (SS) or arginine-vasopressin (AVP) elicits barrel rotation (BR) in rats. To identify the potential neuron structures involved in this characteristic behavior, the regional expression of the c-fos gene in rat brain after i.c.v. injection of SS (10 micrograms) or AVP (1 micrograms) was examined by hybridization histochemistry. The c-fos expression could serve as a marker of neuronal activity and/or neural transmission. Following SS-induced BR, c-fos gene expression was observed in the lingula, uvula, nodulus, simplex, centralis, and culmen of the cerebellum, while following AVP-induced BR, c-fos gene expression was observed in the first four of the above-mentioned regions of the cerebellum, but not in the centralis or culmen. In these regions, the c-fos mRNA signals were observed on the granular layer. Expression of the c-fos gene was immediately and transiently induced and was not observed in rats in which BR was not evoked after SS or AVP injection. In both control rats and SS- or AVP-injected rats, the c-fos gene expression was induced in the piriform cortex and the flocculus of the cerebellum. The findings suggest that BR is a manifestation of behavior induced by massive transsynaptic activation of the granular cells in the cerebellum.
