Ultrasound was used to examine the insula, sylvian fissure (SF), parieto-occipital fissure (POF), and calcarine fissure (CF).
For example, the gestational ages at which the parieto-occipital fissure (POF) was first visualized in these studies varied from 18.5 to 24 weeks.[sup][9],[10] Moreover, very few studies have described the progression of gyration over time.[sup][8],[11],[12] This study aimed to describe and measure the normal ultrasonographic features of cortical sulcus development (especially the insula, SF, POF, and calcarine fissure [CF]) in human fetus between 18 and 41 weeks of gestation in a large Chinese population.
The parietal lobe lies between the central sulcus and the parieto-occipital fissure. The lateral fissure divides the parietal and temporal lobes (Fig 3).
