Abstract

The e-wave of the electroretinogram was recorded intraretinally from dark-adapted frog eyecups. e-Wave latency was roughly proportional to log stimulus intensity, varying from 2 to 65 sec. The delayed response of ganglion cell units (types 3 and 4) began simultaneously with the e-wave. The e-wave response had similar latencies as the onset of the decay phase of the saturated rod response (determined by recording the mass receptor response and by monitoring b-wave threshold). These results suggest that the e-wave and the delayed ganglion cell response represent closely-linked retinal phenomena which are initiated by rod response decay.
