entorhinal cortex
Acronym: ENT
The term entorhinal cortex (ENT) refers to a subdivision of the cerebral cortex defined on the basis of internal structure and function in the human ( Mai-1997 ), macaque ( Paxinos-2009a ), rat ( Swanson-2004 ) and mouse (cos) ( Dong-2004 ). In primates it is located in the anterior parahippocampal gyrus (PHGa) of the limbic lobe (LLB), where it is partially bounded ventrolaterally by the collateral sulcus (cos) in the human and by the rhinal sulcus in the macaque (rhs). Rostrally it is superficiall to the amygdala (AMG). It is dorsomedially and caudally adjacent to the hippocampal formation (HPF). Ventrolaterally it is bounded the ectorhinal cortex (ECT). In the rat ( Swanson-2004 ) and mouse ( Franklin-2008 ) it is located ventrally at the occipital pole (ocp) of the cerebral cortex (CTX).
      . The ENT is subdivided into eight parts in the human ( Insausti-2004 ) and seven parts in the macaque ( Paxinos-2009a ). In the rat and the mouse it is divided into a lateral part of the entorhinal cortex (ENTlt) and a medial part of the entorhinal cortex (ENTme); the latter is further divided into dorsal and ventral zones to produce three subdivisions in the rat ( Swanson-2004 ); The mouse has just two. It's medial part is not divided into zones ( Hof-2000 ). (Updated 10 Dec 2024).
