Spatial distribution of the adaptation field of the surround response mechanisms in type X cat retinal ganglion cells.
The surround response mechanism in on-center X-cells in cat retina was found to be bimodally distributed and weak or nonexistent in the receptive field middle. An on-inhibition measure was used to assess surround mechanism gain.
