Popis: | This paper gives estimates of the SNR for a one-photon signal and the continuous noise of photoreceptor rods. It shows that negative feedback mediated via the horizontal cell needs to be taken into account when the reaction of the retina of the eye to low-level illumination is calculated. The influence of negative feedback increases the SNR by an order of magnitude relative to the signal when it is transmitted from the photoreceptor to the bipolar cell, and this agrees with the experimental data. |
