1. Hyperpolarizing responses up to 30 mV in amplitude were recorded from cones and from certain cells believed to be rods in the isolated retina of the swamp turtle, Pseudemys scripta elegans.2. The responses evoked by weak flashes of light reach their maximum in 100-140 msec in red-sensitive cones, 140-180 msec in green-sensitive cones, and 300-600 msec in the rod-like cells (20 degrees C).3. The cone response evoked by weak flashes of light is linearly related to light intensity and obeys the… CONTINUE READING
