Oscillatory potentials in an ERG primarily reflect the activity of which retinal cells?

Explanation:
Oscillatory potentials are the rapid, small wavelets seen on the rising portion of the ERG b-wave, and they come from the inner retina. The cells most responsible for this fast inner-retina signaling are amacrine cells, which form inhibitory networks in the inner plexiform layer and shape the timing of these potentials. So, the oscillatory potentials primarily reflect amacrine cell activity. Photoreceptors generate the a-wave, and bipolar cells mainly shape the b-wave, while ganglion cells contribute to later components, not the characteristic oscillations.
