entorhinal area
Acronym: ENT

The term entorhinal area refers to a subdivision of the cerebral cortex defined on the basis of topology and internal structure in the human ( Mai-1997 ), macaque ( Paxinos-2009a ), rat ( Swanson-2004 ) and mouse ( Dong-2004 ). It is located adjacent to the amygdala rostrally and adjacent to the hippocampal formation caudally.
In primates it is found in the anterior parahippocampal gyrus of the limbic lobe where it is partially bounded ventrolaterally by the collateral sulcus in the human and by the rhinal sulcus in the macaque. It is subdivided on the basis of internal structure 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 area and a medial part of the entorhinal area; 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 divisible into zones ( Hof-2000 ). (Updated 9 May 2024).
