In the present study the investigators searched for retinal ganglion cells that were transiently excited by saccades in chronically prepared cats. As excitability of LGN cells was suppressed during quick image motion by signals arising in the retina it was assumed that the information might be coded in a burst discharge which would continue for a period comparable to the initial portion of the suppression. It was found that there were at least three classes of ganglion cells in the cat retina that differed in their discharge patterns relating to eye movements scanning a stationary grating pattern. One class of cells showed transient bursts to eye movements and another class of cells showed sustained discharges in certain directions of gaze, reflecting local luminance. There were also cells showing both transient and sustained responses. (Author)
