1. Light adaptation has been studied in isolated red-sensitive cone photoreceptors of the salamander, using suction pipette recordings of circulating current. 2. In the presence of background illumination, the response to incremental dim flashes became desensitized according to the Weber-Fechner law. The recovery phase of the flash response was accelerated significantly, although the time-to-peak was reduced only slightly, and for dim backgrounds the rising phase was unaltered. 3. The role of… CONTINUE READING
