parasubiculum
A transitional zone between the presubiculum and the entorhinal area in the mouse (Paxinos-2001), the rat (Swanson-1998) and the primate (Zilles-1990). Defined on the basis of cytoarchitecture, it is more similar to the presubiculum than to the entorhinal area (Zilles-1990). (from Brain Info).
