Properties of Cone Photoreceptors in Relation to Colour Vision
The chapter by Nunn, Schnapf & Baylor (this volume) describes how primate photoreceptors respond to illumination. I shall be continuing with this theme, describing further important properties of the cone photoreceptors, and discussing the implications of these properties for colour vision. In particular there is one important property of cone photoreceptors, namely their “automatic gain control”, which has profound implications for colour vision, and I shall be expanding in some detail on that. These implications are also mentioned in the chapter by MacLeod (this volume).
