The occipito-temporal lobe has corresponding relations. Posteriorly it isseparated from the occipital lobe by the inferior branch of the primary occipitalarch, 02, fissura occipitalis inferior. It passes forward following the fornix and isseparated from the occipitofrontal as described above. 3. The occipital lobe forms
