They sit behind the temporal and parietal lobes and above the cerebellum, separated from the cerebellum by a membrane called . The occipital lobe is not very perceptible to injury due to its location in the back part of the brain. The occipital lobe comprises the visual cortex, which is the area of the cerebral cortex that information from the retinas reaches first. They are not particularly vulnerable to injury because of their location at the back of the brain, although any significant trauma to the brain could produce subtle changes to our visual-perceptual system, such as visual field defects and scotomas. The occipital lobe is located behind the lateral parieto-temporal line and is composed of a number of irregular convolutions that are divided by a short horizontal sulcus, the lateral occipital sulcus, into the superior and inferior occipital gyri ( Video 2-5).
