Figure 1

A, ERG response of turtle Pseudemys scripta elegans elicited by a 900-ms light stimulus to separate the a-wave and b-wave from the d-wave. B, the ERG of the bullfrog elicited by a long (40-sec) light stimulus to show the c-wave in addition to the a-, b-, and d-waves (4). C, the ERG response of a rabbit to a flash (20 μs) flash of white light. D, the ERG response from a human as typically recorded in the clinic. Note the fast oscillations on the ascending limb of the b-wave. Calibration bars are denoted separately for each ERG response.
