Cerebral sulcus development T2WI map (a-c) (from the left and right are gestational age 69, 85, 114 days respectively) In the E69 group, smooth insula with no anterior or posterior temporal sulcus, visible hemisphere cerebral sulcus, and a lateral cerebral fissure separating the frontotemporal and parietal occipital sulcus (a). In the E85 group, a shallow insular sulcus and gyrus with shallow anterior and posterior temporal sulcus were observed. Fissura calcarina, sulcus ammonis, the anterior central gyrus, the central gyrus, and the posterior gyrus were observed, along with a shallow anterior and posterior frontal gyrus, and anterior and posterior temporal gyrus (b). In group E114, a deep insular sulcus and gyrus, and deepened anterior and posterior temporal sulci were observed, along with a deep anterior and posterior frontal gyrus, anterior and posterior temporal gyrus, and temporal occipital gyrus, as well as a visible frontotemporal gyrus. The lateral fissure of the brain was almost closed, with the insula covered (c)
