The paper introduces a tool to design light stimuli that predictably alter photoreceptor responses, enabling separation of nonlinearities in phototransduction from downstream circuits.

The paper shows On parasol retinal ganglion cells respond linearly to spatial structure in flashed gratings and natural images but nonlinearly to temporally-modulated grating stimuli, due to cone photoreceptor adaptation.

The paper develops a biophysical model of cone phototransduction with fast and slow adaptation mechanisms to explain nonlinear responses to natural visual stimuli.

The paper shows that rod signals in primate retina use a single pathway regardless of light level, contrasting with mouse retina, and identifies light-level-dependent speeding of signals from rods themselves.
