Final answer:
Damage to the occipital lobe affects vision, as it is responsible for processing visual information from the eyes such as seeing, recognizing, and identifying objects and people.
Step-by-step explanation:
Damage to the occipital lobe can interfere with the processing of information coming in through the eyes, which is indicative of its role in vision. The occipital lobe, located at the back of the brain, contains the primary visual cortex and is essential for seeing, recognizing, and identifying the visual world. It is organized in a retinotopic manner, meaning there's a direct correlation between an object's location in the real world and how it's represented on the cortex.
Visual information is processed in the occipital lobe where it begins, but that information also continues into two streams into the temporal and parietal lobes. Damage to the occipital lobe or along the optic pathway can result in deficits like prosopagnosia, which is the inability to recognize faces, or a loss of peripheral vision due to lesions affecting the optic chiasm.
