Inhibitory input shapes timing of responses to full-field noise stimuli in midget but not parasol cells. A, Spike rate of example On midget cell during dynamic clamp experiments using conductances elicited by full-field Gaussian noise stimuli. Firing rate for repeated trials injecting currents corresponding to both excitatory and inhibitory conductances (black) or excitatory conductance alone (gray). B, Autocorrelation function of firing rates for dynamic clamp experiments with and without inhibitory conductance for same cell as in A. C, Autocorrelation width with and without inhibitory conductance for population of cells. D–F, As in A–C but for On parasol cell dynamic clamp experiments.
