Abstract : Recently very sensitive enzymatic assays have been developed for several neurotransmitters and putative transmitters which make it possible to assay these substances in single nerve cells of Aplysia. The authors have measured the concentrations of 5-HT, histamine, octopamine, dopamine and norepinephrine in the large identified cells from the various ganglia. In this communication studies are reported on four neurons: R2, R14, L11 and C1. These neurons and others have been found to contain more than one putative neurotransmitter.
