The Limit of Photoreceptor Sensitivity: Molecular Mechanisms of Dark Noise in Retinal Cones
Detection threshold in cone photoreceptors requires the simultaneous absorption of several photons because single photon photocurrent is small in amplitude and does not exceed intrinsic fluctuations in the outer segment dark current (dark noise). To understand the mechanisms that limit light sensiti...
