Occipital Lobe

Occipital lobe is the smallest of the four lobes and rests on the tentorium cerebelli and is anteriorly separated from the parietal lobe and temporal lobe by the parieto-occipital sulcus (imaginary line extending from the pre-occipital notch of the temporal lobe superiorly to the parieto-occipital sulcus) (Fig. 11.1). Only a small part of the dorsolateral surface is occupied by the occipital lobe which occupies a large part on the mesial aspect of the brain in between the parietal and temporal lobes (Fig. 11.2). The calcarine fissure divides the mesial occipital lobe surface into the cuneus above and the lingual gyrus below.
