agranular insular cortex
Acronym:
The term agranular insular cortex refers to a portion of cerebral cortex identified in the rat ( Swanson-2004 ) and mouse ( Dong-2004 ) on the basis of internal structure. Lacking granular layers, it is located on the ventrolateral surface of the cerebral cortex rostrally; it is dorsal to the piriform area and ventral to the gustatory cortex and the visceral area ( granular insula ). In rodents it has three subdivisions: dorsal part of the agranular insular area, ventral part of the agranular insular area, and posterior part of the agranular insular area. In the functional CNS model it is a subdivision of polymodal association cortex ( Swanson-2004 ). It is most likely equivalent to the insulo-orbital agranular cortex of the human ( Ongur-2003 ) and the macaque ( Carmichael-1994 ).
