Posterior View of Another Left Hemisphere. A, Posterolateral view of the left hemisphere. In this specimen, the lunate sulcus is identified, and it partially isolates the occipital pole from the superior and inferior occipital gyri. It is possible to identify gyral connections with the superior and inferior occipital gyri (asterisk). B, Posterior view of another left hemisphere. Frequently the superior and the inferior occipital gyri converge posterior to the distal extremity of the lateral occipital sulcus to form the occipital pole. (Images courtesy of E de Oliveira)
