Precentral sulcus

Last revised by Assoc Prof Craig Hacking on 19 Apr 2018

The precentral sulcus is one of the major sulci of the frontal lobe, running in front of and parallel to the central sulcus, separated from it by the precentral gyrus. Inferiorly it reaches the Sylvian fissure, with the pars opercularis of the inferior frontal gyrus anterior to it and the inferior most part of the precentral gyrus (or more precisely the anterior part of the subcentral gyrus) posterior to it 1,3
