“…In addition to more Ca 2+ entering into the cone OS relative to the rod OS, cone OSs are also more efficient at Ca 2+ extrusion. Extrusion of Ca 2+ is 4-8 times faster in cones compared to rods (7)(8)(9). This is consistent with a much faster and efficient light adaptation in cones compared to rods.…”

“…They also found that light hyperpolarized the membrane potential to ~ −70 mV (9). Photoreceptors therefore respond to stimulation in the opposite way from most CNS neurons, which tend to depolarize when activated.…”

“…Although a light-elicited conductance decrease has been measured in some preparations (Toyoda, Nosaki & Tomita, 1969;Toyoda, Hashimoto & Anno, 1970), no conductance change was measured in mudpuppy (Werblin, 1975) and a conductance increase has been measured in tiger salamander (Lasansky & Marchiafava, 1974).…”

“…Ion substitution experiments indicate that this current is carried by sodium ions which, in the dark, enter the outer segment and maintain the photoreceptor in a depolarized state (2)(3)(4). Light stimulation interrupts this current and hyperpolarizes the photoreceptor's membrane (1,5,6). Intracellular recording indicates that the cessation of this current is accompanied by a conductance decrease in at least some preparations (7,8).…”
