Abstract:
Numerous green-fluorescent neurons have been revealed by means of the glyoxylic acid histochemical method in cryostat sections of several organs of two Adriatic aplysiid gastropods, Aplysia depilans and A. fasciata. Catecholamine-containing perikarya and their processes have been found to be especially abundant in the vaginal portion of the large hermaphrodite duct, in the penis and its sheath, and in the gill. In the reproductive organs, two subpopulations of catecholamine-containing neurons could be distinguished according to their size and location. Axons of larger neurons formed bundles which seemed to project at the CNS.
