Postcentral sulcus

(anatomy) The first sulcus of the parietal lobe of the cerebrum, lying behind and roughly parallel to the central sulcus.

The sulcus that demarcates the postcentral gyrus from the superior and inferior parietal lobules.

The postcentral sulcus of the parietal lobe lies parallel to, and behind, the central sulcus in the human brain. (A sulcus is one of the prominent grooves on the surface of the brain.)

The postcentral sulcus divides the postcentral gyrus from the remainder of the parietal lobe.
