title: Influence of GABA on the spectral and spatial coding of goldfish retinal ganglion cells.
abstract: The responses of center red ON and center red OFF ganglion cells of the isolated goldfish retina to a flickering stimulus light diminish by GABA. Without stimulation GABA blocks the maintained activity of the OFF cells. With a green flickering spot in the receptive field center, the green ON-response of the OFF cells becomes an OFF-response during GABA administration. It is concluded that, besides the common antagonistic green input, the receptive field center of these cells also has a synergistic green input, which is mediated by a pathway other than the center opponent red and green inputs.
