The temporal lobe of the brain is often referred to as the neocortex.

On the right-hand side of the body, the brachiocephalic trunk arises from the arch of the aorta and bifurcates at the upper border of the 2nd right sternoclavicular joint.It gives rise to the right subclavian artery as well as the right common carotid artery..

This is because the brain has a relatively high metabolic demand, due to being largely reliant on oxidative metabolism.
