agranular insular cortex (Roberts)
Acronym: AI
The term agranular insular cortex (Roberts) refers to a portion of the insula defined on the basis of internal structure in primates. In the human ( Roberts-1970 ) it is located in the anterior insula between the orbital gyri rostrally and the dysgranular insular cortex (Roberts) caudally. In the macaque ( Roberts-1963, Paxinos-2009a ) its rostral border is with the fronto-orbital gyrus (macaque).
     Note that it is not the same as the agranular insula or the agranular insular area ( Mesulam-1984, Zilles-2012 ). Differences in criteria for identifying agranular, dysgranular, and granular architectonic areas have led to two different segmentations of the insular cortex in primates.
