Extended Data Fig. 2: Signal and noise correlations, information rates, and Fano factors in the marmoset retina.

a, Total cross-correlation (black) for a pair of ON parasol cells and a shuffle predictor of signal correlation (red) for the natural movie (top) and white noise (bottom), using the repeated stimulus sections of both stimuli. The shuffle predictor was generated by averaging cross-correlations calculated after randomly permuting trials of the repeated stimulus (natural movie or white noise) 15 times. b, Noise correlations were estimated by subtracting the shuffle predictor from the total correlation. Shaded area marks the area used for summarizing noise correlations. c, For each cell type, the area under the noise cross-correlation curve is plotted against receptive field distance for natural movie (top) and white noise (bottom) data. d, Cell-type-specific information rates for different response frequencies under the natural movie (colored) or spatiotemporal white noise (grey). Colored lines represent averages for pairs at similar x-coordinates (with 95% confidence intervals) within the same ganglion cell type. e, Fano factor histograms for cell responses to the natural movie. Fano factors were averaged over fixations for each cell, and for each cell type, the median across cells (with 95% robust confidence intervals in parentheses) is reported in the figure. Data from 3 retina pieces.
