Neurobiology of vision

The neurobiology of vision involves how your eyes detect light and how this information is processed by your brain to create what you see. Light enters the eye through the cornea and lens, hitting the retina where specialized cells called photoreceptors (rods and cones) convert light into electrical signals. These signals travel via the optic nerve to the brain's visual cortex, primarily in the occipital lobe. The brain then interprets these signals, allowing you to perceive shapes, colors, depth, and motion. This complex process integrates sensory input and neural computation to produce a coherent visual experience.
