title: Transmitter-specific retrograde labeling in the striato-nigral and raphe-nigral pathways.
abstract: Injecting radioactive transmitters into the rat substantia nigra led to retrograde neuronal labeling either in the dorsal raphe nucleus, after 3H-labeled serotonin injection, or in the caudoputamen, after 3H-labeled gamma-aminobutyric acid injection. This differential labeling in projections whose transmitter has been established provides the basis for a histochemical tracing method indicating both connectivity and transmitter specificity of neural pathways.
