Where is the central sulcus located?
It separates the parietal lobe and the frontal lobe.

What is the cerebral cortex gross structure made up of...
A sulcus is a shallower groove that surrounds a gyrus. A fissure is a large furrow that divides the brain into lobes and also into the two hemispheres.

In conjunction with a loop involving the cerebellum: to select and trigger well coordinated voluntary movements
