The labels here are mostly self-explanatory.

Corpus callosum : R : Rostrum, G : Genu, Sp : Splenium. The part between the genu and the splenium is the body of the corpus callosum.

The parieto-occipital and calcarine sulci extend slightly on to the superolateral surface (not seen here).

Note the cingulate sulcus with the gyrus between it and the corpus callosum.

At the upper end see the tip of the central sulcus. The loop around it, marked with a black line is the paracentral lobule.

Additional questions :

What is the functional cortical area in the walls of the calcarine sulcus. Why is it called the "striate cortex"? What is the blood supply of this part of the cortex? What is the importance of the cortical area around the tip of the calcarine sulcus?

What are the types of fibres in the white matter of the cerebrum? What type of fibres is the corpus callosum made of?

Terms : Rostrum = beak. Genu = knee (bend). Cingulum = girdle (around the corpus callosum). Corpus callosum = the "tough body" - it is 'harder' than the rest of the brain substance because of the compact arrangement of fibres. 'Callum' in Latin also means a beam or a rafter - well, the anatomist's (in this case Galen) imagination!
