Which sulcus is associated with visual processing in the brain?

The calcarine sulcus is a significant anatomical landmark in the brain that plays a crucial role in visual processing. Located in the occipital lobe, the calcarine sulcus serves as the primary cortical area for the processing of visual information. The primary visual cortex, also known as V1 or area 17, is situated along the banks of this sulcus. This area is responsible for the initial processing of visual stimuli received from the retina through the lateral geniculate nucleus of the thalamus.

When visual information is transmitted from the eyes, it is first relayed to the visual cortex, where simple visual features such as contrast, orientation, and motion are analyzed. The organization of the calcarine sulcus allows for the orderly representation of the visual field, contributing to the ability to perceive and interpret visual stimuli. This makes the calcarine sulcus essential for understanding how the brain processes sight and integrates visual information into coherent images.

In contrast, the central sulcus primarily separates the frontal and parietal lobes and is associated with motor and sensory functions rather than visual processing. The lateral fissure (Sylvian fissure) separates the temporal lobe from the frontal and parietal lobes and has a
