Abstract
THE early receptor potential (ERP) of the retina is a rapid electrical response to an intense flash of light1. Typically, an initial cornea-positive wave of negligible latency, R1, is followed by a negative potential, R2. If the ERP is recorded from a living eye, the a-wave of the relatively slow electroretinogram arises from the ascending portion of R2 (Fig. 1A). Unlike the electroretinogram, however, the ERP is not dependent on neural activity for its formation, and the R1 and R2amplitudes are linear functions of the number of visual pigment molecules bleached2.
