Retina has pigment cells {photoreceptor cell}, with three layers: cell nucleus, then inner segment, and then outer segment with photopigment. Visual-receptor cells find illumination logarithm.
types
Human vision uses four receptor types: rods, long-wavelength cones, middle-wavelength cones, and short-wavelength cones.
hyperpolarization
Visual receptor cells hyperpolarize up to 30 mV from resting level [Dowling, 1987] [Enroth-Cugell and Robson, 1984] [Wandell, 1995]. Photoreceptors have maximum response at one frequency and lesser responses farther from that frequency.
