Q

Sulci and gyri

A

● Sulci (grooves or ditches in brain) vs. gyri
(outpouching in brain) → maximize
brain’s surface area
● The central sulcus separates the frontal
lobe (rostral to the central sulcus) and
parietal lobe (caudal to the central
sulcus)
○ Precentral gyrus is immediately rostral to the
central sulcus
○ Postcentral gyrus is immediately caudal to the
central sulcus
