Physiology and Perception of the Eye

This podcast focuses on the eye. It begins with a brief overview of the eye’s anatomy and physiology. The discussion then shifts to rods, cones, and the phototransduction pathway. The final section addresses perception.


Key topics include visual field processing, differences between binocular and monocular cues, and feature detection (covering both Magno and Parvo pathways).
