gyrus supramarginal gyrus true Component of the parietal lobe. The first coronal slice between the superior temporal gyrus and the postcentral gyrus where the supramarginal gyrus appears was the rostral boundary whereas the slice where the supramarginal gyrus becomes continuous with the superior parietal gyrus was the caudal boundary. The medial and lateral boundaries were the lateral banks of the intraparietal sulcus and the medial banks of the lateral fissure and/or the superior temporal gyrus respectively (Christine Fennema-Notestine).
