Abstract

In the rhesus monkey the action spectrums for eliciting DC responses and rod-mediated ERG's are not identical. Long wavelengths are relatively more effective than short wavelengths in eliciting DC responses, indicating that cone receptors must be contributing to the DC response. The relative effectiveness of short wavelengths for evoking DC responses increases with dim light stimulation, suggesting that a Purkinje shift occurs.
