Abstract
2-Amino-4-phosphonobutyrate (APB) is known to selectively suppress the light response of ON bipolar cells in the vertebrate retina, and reduce the b-wave of the electroretinogram (ERG) as a consequence. Using slow drug application, the progressive effect of APB was used to compare the relative response amplitudes of the b-wave and the ON bipolar cell. Simultaneous ERG recordings and ON bipolar intracellular recordings were performed in the amphibian retina. The results indicate that there is a strong positive correlation between these two waveforms. This supports the possibility that the b-wave of the ERG is the direct result of ON bipolar cell activity.
