Abstract
RADIANT energy absorption in chickens normally occurs in the molecules of the vitamin A1-based rod and cone pigments rhodopsin and iodopsin. The participation of rhodopsin and iodopsin in scotopic and photopic vision, respectively, has been demonstrated by the Purkinje shift, both in behavioural1 and in electroretinographic experiments2.
