Abstract
This paper describes ERG's obtained from all rod retinas containing essentially only a-waves. Albino rats, treated with sodium glutamate, were used. The fractionated ERG's obtained from dark adapted rats were in response to stimuli of varying intensity, duration, and wave length. Others were taken during the recovery from light adaptation. A small b-wave was present whenever an a-wave was absent. In the presence of an a-wave, the b-wave appeared only as a very small positive deflection at the peak of the a-wave. The a-waves obtained in these experiments are compared with those obtained from untreated albino rats. The a-wave appears unaffected by the sodium glutamate treatment.
