area 8Av
Acronym: 8Av
The term area 8Av refers to the more ventral of two components of area 8A. In the human it is located posteriorly in the middle frontal gyrus. Defined on the basis of multiple stains, it is bounded rostrally by area 9/46v, caudodorsally by area 6; caudoventrally by area 44 and dorsally by the other component of area 8A, area 8Ad.
     Its equivalent in the macaque is similarly located with its lower boundary at the inferior ramus of the arcuate sulcus and its upper boundary partially defined by the principal sulcus ( Petrides-2012 ). As granular prefrontal cortex, it has no equivalent in the rat ( Zilles-2012 ).
