part of part of regional part of brain orbitofrontal cortex medial orbital frontal cortex Component of the orbtial frontal cortex. The rostral boundary is the first slice where the medial orbital gyrus became visible whereas the caudal boundary is the disappearance of the medial orbital gyrus/gyrus rectus. The medial and lateral boundaries are the cingulate cortex on the u2018inflatedu2019 surface and the medial bank of the superior frontal gyrus (or the cingulate gyrus when visible) respectively (Christine Fennema-Notestine).
