032 Visual Processing in the Retina

In episode 32, Leslie Samuel explores visual processing in the retina, focusing on how light and dark conditions affect the behavior of rods and cones. The episode reviews the role of sodium ions, cyclic GMP, and neurotransmitters in depolarization and hyperpolarization. It also covers the functions of various retinal cells, including bipolar and ganglion cells, and explains how signals are transmitted to the brain via the thalamus. The episode provides a comprehensive overview of the visual processing mechanisms in the retina.
