Figure 5. Rod-signals generated by sine-wave stimuli are also restricted to the RB pathway at backgrounds of ~20 R*/rod/s and ~200 R*/L cone/s.

(A) Excitatory synaptic input recorded from an On parasol RGC in response to sinusoidally-modulated short (rod-preferring; blue traces) and long (cone-preferring; red traces) wavelength stimuli. Contrasts were adjusted to produce equal modulation at 2 Hz and were then held fixed for all subsequent recordings (e.g. different frequencies, horizontal recordings). (B) Population data from On parasol RGC recordings (n=2) plotting response modulation versus stimulus frequency. (C) Voltage response of an H1 horizontal cell (from the same retinal mount) to short and long wavelength stimuli for the same contrast used for the parasol cell in A. (D) Population data from H1 horizontal recordings (n=4) plotting response modulation versus stimulus frequency.

(A) Spike responses to 15 Hz flicker in On parasol RGCs across a range of backgrounds. (B) Responses across frequencies and backgrounds. Averaged spike responses for each cell were fit with sine waves matched to the stimulus frequency. The amplitudes of these fits were used for this analysis. Plot collects data from 4 On and 4 Off parasol cells (mean ± SEM).
