Running parallel to the central sulcus is the precentral sulcus, which lies at the posterior end of the frontal lobe. The inferior frontal gyrus is further divided by the anterior ascending and the posterior rami of the sylvian fissure into the pars orbitalis, triangularis, and opercularis. The...
They are demarcated posteriorly by the central sulcus, laterally by the Sylvian fissure, and medially by the cingulate sulcus. The frontal lobes are anatomically and functionally heterogeneous, and the lateral surface of the frontal lobes can be divided into three major functional sectors: primary ...
for the case of CSDs, parts or all of the second gyrus are sometimes assigned to the PT regardless of the length of the sulcus intermedius, even though according to conventional definitions of HG, the second gyrus

2.1). The temporal lobe is separated dorsally from the frontal and parietal lobes by the Sylvian fissure. The inferior limiting sulcus, part of the circular sulcus of Reil, separates the temporal lobe from the insula at the fundus of the Sylvian fissure (Fig. 2.2). Sign in to download hi...
These demarcate the superior frontal gyrus (above the superior frontal sulcus), inferior frontal gyrus (below the inferior frontal sulcus), and middle frontal gyrus between the two. These are well shown on coronal MR images. The precise pattern of sulcation varies a great deal, but most ...
