Abstract：
:Conspicuous nerve-cell assemblies, identified as the marginal nuclei described in other sauropsidans, were found all along the spinal cord of turtles. gamma-aminobutyric acid (GABA) and nitric oxide synthase (NOS) activities were colocalized within these neurons, which also reacted positively to reduced nicotinamide adenine dinucleotide phosphate-diaphorase stains. The marginal nuclei neurons may, thus, play an inhibitory function mediated by their GABA terminals and a long-distance modulatory function mediated by NO liberation.
