Receptor Potentials from a Visual Pigment with Two Thermally Stable States
There are a number of references in the literature to “long-lived” secondary states of visual pigments (summarized by Arden, 1969; also see Brown and White, 1971). Weale (1967) has suggested that these (and other) states might participate in the visual process. There has however, been no direct demonstration of the contribution of any long-lived state to the early receptor potential (ERP) or late receptor potential (LRP).
