Lateral cortical surface

The middle frontal gyrus (MFG) is usually more sinuous than the inferior frontal gyrus or superior frontal gyrus and it often connects to the precentral gyrus via a thin isthmus 1)

The central sulcus joins the Sylvian fissure in only 2% of cases (i.e. in 98% of cases there is a subcentral gyrus). The intraparietal sulcus (ips) separates the superior parietal lobule and inferior parietal lobules.

The inferior parietal lobule is composed primarily of the angular gyrus and supramarginal gyrus. The Sylvian fissure terminates in the supramarginal gyrusSMG (Brodmann area 40). The superior temporal sulcus terminates in the angular gyrus.
