Ability of the visual system

How eyes and brain detect, process, and interpret visual information

Neuroscience • Visual Perception / Visual Neuroscience🚀 Beginner

An introduction to how the visual system captures light, transmits signals, and constructs perceptual representations. Learners will grasp core components from retina to visual cortex and basic perceptual abilities such as edge detection, motion, and color.
