Which region receives and processes visual input from the retina?

• A. Occipital lobe
• B. Primary visual cortex
• C. Visual association area
• D. Temporal lobe

Answer: (A)

Visual processing starts as soon as light signals are transduced by the retina and then routed into the brain. These signals are sent to the primary cortical destination for vision, which lies in the occipital lobe. The occipital lobe houses the primary visual cortex, the first cortical area to receive retinal input and begin basic processing of visual features like edges and motion. From there, higher visual areas handle more complex interpretation. The temporal lobe is more involved in object recognition over time, and the visual association areas perform further processing within the visual cortex, but the initial reception and primary processing of retinal input occur in the occipital lobe.
