Which sulcus delineates the parietal lobe from the occipital lobe?

The parieto-occipital sulcus is the structure that delineates the parietal lobe from the occipital lobe. This sulcus runs in a medial to lateral direction on the medial aspect of the hemisphere and serves as a boundary between these two lobes of the brain.

Understanding the location of the parieto-occipital sulcus is crucial in neuroanatomy as it is involved in distinguishing the functions attributed to these different lobes. The parietal lobe is primarily associated with sensory processing, spatial awareness, and coordination, while the occipital lobe is primarily responsible for visual processing. By delineating these two regions, the parieto-occipital sulcus plays a key role in the organization of brain function and the integration of sensory information.

The other structures listed do not serve this specific purpose of separating the parietal and occipital lobes. The central sulcus separates the frontal lobe from the parietal lobe, while the pre-occipital notch marks the boundary between the temporal lobe and the occipital lobe. The cingulate sulcus is involved in delineating the cingulate gyrus from the frontal and parietal lobes. Therefore,
