The presence of GABAergic cells and fibres in the corpus cerebelli and auricles of a dogfish, Scyliorhinus canicula, was studied with immunocytochemistry. In both locations, two types of GABA-immunoreactive (GABA-ir) neurons were observed: stellate cells in the molecular layer and Golgi cells in the granular layer. Stellate cell axons gave rise to numerous GABA-ir boutons distributed throughout the molecular layer and a smaller number of boutons which contacted Purkinje cell perikarya. No GABA-ir baskets around Purkinje cells were observed. Golgi cells of the granular layer gave rise to numerous GABA-ir boutons which were located around cerebellar glomeruli. Purkinje cell perikarya and their axon terminals in the cerebellar nucleus were not GABA-immunoreactive. These findings are discussed in terms of the phylogeny of cerebellar circuits.
