Visual Cortex - English Definition & Meaning

Definition

The visual cortex is the region of the cerebral cortex primarily responsible for processing visual information. Located in the occipital lobe at the back of the brain, it receives signals from the eyes via the optic nerves. It is divided into several areas that process different aspects of vision, such as shape, color, and motion. It's like the brain's dedicated graphics card for rendering the world. Damage to the visual cortex can cause blindness or visual distortions. Visual information is highly processed in this area.

Etymology

'Visual' comes from the Latin 'visualis,' meaning 'of or pertaining to sight.' 'Cortex' comes from the Latin 'cortex,' meaning 'bark' or 'outer layer.' 'Visual cortex' therefore refers to the outer layer of the brain that deals with sight. Its use became common with detailed brain mapping in the 20th century.
