In the human brain, the rhinencephalon appears as a longitudinal elevation, with a corresponding internal furrow, on the under surface of the hemisphere close to the lamina terminalis; it is separated from the lateral surface of the hemisphere by a furrow, the external rhinal fissure (or rhinal sulcus), and is continuous behind with that part of the hemisphere, which will ultimately form the anterior end of the temporal lobe.
