Adaptation in cones. A general model.
Three features appear to characterize steady-state light adaptation in vertebrate cone photoreceptors: (a) the shape of the "log intensity-response" curve at different levels of adaptation is the same, the only change with adaptation is in the position of the point on the curve about which the cones operate; (b) at high adapting intensities the operating point becomes fixed in position; (c) this fixed position is at the steepest point of the log intensity-response curve. These three features can be described by a mathematical model.
