Receptive field properties of x and y cells in the cat retina derived from contrast sensitivity measurements


, : Receptive field properties of x and y cells in the cat retina derived from contrast sensitivity measurements. Vision Research 22(9): 1173-1184

The contrast sensitivity to gratings drifting at 2.0 Hz was measured for X and Y type retinal ganglion cells, and these data were used to characterize the sizes and peak sensitivities of centers and surrounds. The assumption of Gaussian sensitivity distributions is adequate for both types of cells, but allows a better description of X than of Y cells. The size and peak sensitivity can be specified more precisely, in general, for the center than for the surround. The data also show that for both types of cells; center radius increases with eccentricity, but is 2-3 times larger for Y cells than for X cells at a given eccentricity; spatial resolution is an excellent predictor of center size; the larger the center or surround, the lower its small spot sensitivity at a specific mean luminance; and the surround is nearly as strong as the center for large or diffuse stimuli. X cell surrounds are relatively weaker in the middle of the receptive field than Y cell surrounds, but X cell surrounds are larger relative to their centers.
