031 How Rods and Cones respond to Light

In this episode, Leslie Samuel explains how rods and cones in the eye respond to light. The video covers the process of light entering the eye, focusing on the retina, and interacting with rhodopsin in rods. It details the biochemical reactions involving rhodopsin, transducin, and phosphodiesterase, leading to changes in membrane potential and neurotransmitter release. The video emphasizes the unique process in rods where light causes a decrease in neurotransmitter release, contrasting with typical depolarization processes.
