Uncus

The uncus is an anterior extremity of the Parahippocampal gyrus. It is separated from the apex of the temporal lobe by a slight fissure called the incisura temporalis.

Although superficially continuous with the hippocampal gyrus, the uncus forms morphologically a part of the rhinencephalon.

The term uncus was coined by Felix Vicq d’Azyr (1748–1794).
