The primary visual cortex, also known as V1, is the first area in the brain that processes visual information. Located in the occipital lobe, it receives input from the retina through the thalamus. This region is crucial for interpreting basic visual features such as edges, colors, and motion. In the primary visual cortex, neurons are organized in a way that allows them to respond to specific visual stimuli. This organization helps the brain construct a coherent image from the raw data received from the eyes. The primary visual cortex plays a vital role in our ability to perceive and understand the visual world around us.
