primary visual area

The primary visual area, also known as the visual cortex, is located in the occipital lobe at the back of the brain. This area is crucial for processing visual information.12

The visual pathway begins with the optic nerves, which carry signals from the retinas to the brain. These signals travel through the lateral geniculate nuclei (LGN) in the thalamus, which act as relay stations, before reaching the primary visual area.3

Within the visual cortex, neurons are organized to detect specific features of an image, such as lines, edges, and their orientation. Different parts of the cortex specialize in processing aspects like color, depth, and motion, contributing to our conscious perception of the visual world.43
