The posterior frontal sulcus (or furrow) is just behind andparallel with the coronal suture (Plate 2, Fig. 2, No. 4). It is some-times called the vertical sulcus. The ascending frontal convolution isbetween the posterior frontal sulcus and the fissure of Rolando. The upper end of the posterior frontal sulcus reaches to about themiddle of the fissure of Rolando. The inferior frontal sulcus branches offfrom it about on a level with the superior stephanion, which is the pointof intersection of the coronal suture and the ridge
