area Ial
Acronym: Ial
The term area Ial refers to one of four subdivisions of the agranular orbitofrontal cortex. Defined on the basis of multiple stains, it is located on the lateral part of the posterior orbital gyrus. Occupying the dorsal wall of the anterior horizontal limb of the lateral fissure, it is bounded medially by area Iai, and caudally by the agranular sector of the insula. The other three subdivisions of the agranular orbitofrontal cortex are area Iam, area Iapm, and area Iai. For the relations of this segmentation and terminology to others, see Ongur-2003.
     Its equivalent in the macaque is area Ial (macaque) ( Carmichael-1994 ). For equivalent areas in the rat and mouse, see agranular insular cortex.
