Figure 4. Subunit model predicted responses to repeated white noise.

(A) Average firing rate of a single OFF midget RGC to an 8 s white noise stimulus repeated 100 times. Purple, prediction of subunit model; green, prediction of LN model. Both models were fit to independent data using non-repeated white noise stimuli. Bin width, 83 ms. (B) Adjusted R² (see ‘Materials and methods’) for the two models; each point shows performance for one OFF midget RGC.
