title: GABAergic ganglion cells in the rabbit retina.
abstract: The ganglion cells are the output neurons of the retina. There is, however, relatively little known about the neurotransmitters used by these cells. In the present study, ganglion cells identified with a ganglion cell-specific monoclonal antibody (AB5) are shown in separate double-label experiments to be gamma-aminobutyric acid (GABA)-like immunoreactive and to possess a high-affinity uptake mechanism for [3H]GABA accumulation. The localization of these markers of GABA activity to AB5-labelled ganglion cells provides the first definitive evidence for the presence of a classical transmitter in retinal ganglion cells and suggests that GABA may perform a role as a neurotransmitter in these cells.
