Rhinal sulcus

Last revised by Craig Hacking on 13 May 2018

The rhinal sulcus is located on the anteromedial surface of the temporal lobe. It curves in an anteroposterior direction and separates the uncus from the temporal pole. Some sources consider it to be an extension of the collateral sulcus 1-4. The grey matter overlying the rhinal sulcus has been used intraoperatively as an anatomical landmark for locating the temporal horn during amygdalohippocampectomies 5.
