The "Preoccipital notch", "Central sulcus", "Calcarine sulcus", "Parieto-occipital sulcus", "Longitudinal fissure", and "Cingulate sulcus" are features visible on the lateral aspect of the brain that are useful for separating the parietal and occipital lobes. From the medial view of the mid-sagittal brain, the "Parieto-occipital sulcus", "Preoccipital notch", "Central sulcus", "Longitudinal fissure", "Cingulate sulcus", and "Calcarine sulcus" are the structures that separate the same two lobes.
