Abstract
A theory is presented which predicts the electrical responses of frog rods during light and dark adaptation. It is based upon the recent physiological studies. The central points in the theory are that: blocking particles released from rod disks block sodium channels; blocking particles are inactivated by the active transport across the disk membrane; energy spent in the transport is supplied with a light-dependent rate. There was agreement between the properties of real and model rods: the responses to flashes and 47 s pulses; the rate of change of potential after a pulse; frequency response characteristics at different mean illuminances.
