Abstract
Glycine concentrations in individual cell bodies of the identified giant neurons R3–R14 in the parietovisceral ganglion of the mollusc Aplysia californica are up to 20 times higher than in neighboring neurons (Iliffe et al., 1977). High concentrations of putative neurotransmitters are present in invertebrate neurons thought to use those compounds as transmitters (Otsuka et al., 1967; Rude et al., 1969; McCaman et al.; Weinreich et al., 1973). In vertebrates, relatively high concentrations of glycine are present in the ventral grey matter of the spinal cord (Aprison et al., 1975), where glycine is probably used as an inhibitory neurotransmitter by interneurons (Davidson, 1976; Johnston, 1976). Glycine may, therefore, be in high concentrations in R3–R14 for use as a neurotransmitter, particularly since other putative transmitters have not been found in these neurons (Cottrell, 1974; McCaman et al., 1976).
