Abstract
The fast oscillation is a damped oscillatory wave with a period time of 2.5 min. It generally appears superimposed on the slow oscillation which has a period time of 25 min. Microelectrode recordings across the retinal pigment epithelium in intact eyes of macaca speciosa showed that both fast and slow oscillation are generated in this structure. The neural retina yields no contribution to these components. A similar conclusion was recently reached by Griff and Steinberg for an isolated preparation of the gecko retina (ARVO, 1982). Despite extensive manipulation of the stimulus parameters the fast oscillation always had a much smaller amplitude than the slow oscillation. In fact no more than one negative and one positive deflection could be discerned.KeywordsPublic HealthRetinal Pigment EpitheliumSmall AmplitudeRetinal PigmentPigment EpitheliumThese keywords were added by machine and not by the authors.
