Choline acetyltransferase activity in the cerebellum and in centers of lateral line system of teleosts.
Using choline acetyltransferase as a marker of cholinergic activity, different cerebellar areas and brainstem nuclei were assayed in the goldfish and the catfish. Enzyme activity resulted remarkedly higher in archicerebellum than in paleocerebellum. In addition three brainstem nuclei related to lateral line system, showed high or very high levels of choline acetyltransferase. The results suggest that cholinergic transmission would play an important role in central circuits of lateral line system, including the projection towards archicerebellar areas.
