In the human brain, the entorhinal cortex appears as a longitudinal elevation anterior to the parahippocampal gyrus, with a corresponding internal furrow, the external rhinal sulcus (or rhinal fissure). The rhinal sulcus separates the parahippocampal uncus from the rest of the temporal lobe in the neocortex.[1] The rhinal sulcus and the hippocampal sulcus were both present in early mammals.[1]
It is analogous to the collateral fissure found further caudally in the inferior part of the temporal lobe.
