Results for RGC simulations with heavy-tailed inputs. (A) Histograms of excitatory conductances, for the original (left) vs. monophasic (right) filter. The marginal statistics are heavy-tailed skew (top) and Cauchy (bottom) inputs, and refresh rate is 40 ms for both panels. The input standard deviation (expressed as a fraction of baseline light intensity) was 1/2 for both simulations. (B) Sample 100 ms stimuli, filtered by the original linear filter L_exc (top) and altered, monophasic filter L_exc,M(bottom). Cauchy (blue solid), Gaussian (red dashed), and bimodal (green dash-dotted) stimuli are shown.
