title: Colocalization of substance P and gamma-aminobutyric acid in amacrine cells of the cat retina.
abstract: Substance P and gamma-aminobutyric acid (GABA) were colocalized by immunocytochemistry in two subpopulations of amacrine cells in the cat retina. All of the cells which stained for substance P also showed GABA reactivity. However, there were many GABA-immunoreactive cells which did not stain for substance P. The presence of neuropeptides provides a basis for additional neurochemical characterization of the multiple populations of GABA immunoreactive cells.
