Acronym: un
The term uncus refers to a superficial feature of the rostral part of the parahippocampal gyrus where it "hooks around the hippocampal fissure to form a medially protruding convolution" on the anteromedial surface of the temporal lobe ( Carpenter-1983 ). In the human, the underlying structures include the anterodorsal part of the entorhinal area rostrally and the portion of the hippocampus that bends back on itself caudally ( Mai-1997 ). In the macaque it is formed entirely by the hook portion of the hippocampus ( Paxinos-2009a ). Brain atlases of the rat and mouse show no equivalent feature.
