   Abstract:
   Techniques were developed to record retinal ganglion-cell responses. Categories of cell types in the cat retina were established in which X, Y, and W cell types were found with both cones and rods. The cones were connected in combinations selected from three groups whose γ(max) were 450, 500, and 555 nm. The receptive field organization showed center-surround characteristics interaction, including antagonism between cone types. Strong light adaptation showed independence of each cone group from any other in their influence upon the ganglion cells, which was confirmed by the separate recovery of sensitivity by each group. Both the loss and recovery of sensitivity in various parts of the receptive field were demonstrated. No special deleterious effects of strong light adaptation on the 450 λ(max) cone were observed. Good stability of recording techniques was achieved with single cells maintained 10 hours or more. The central portion of the retina was studied intensively, demonstrating the feasibility of recording from the macular or foveal region in rhesus monkeys.
