area 12o (macaque) (12o)
The term area 12o (macaque) An identifying feature of area 12o is the sparsity of myelination revealed by myelin stain. Features that distinguish it from some adjacent areas are a weakly stained internal granular layer (IV) and lack of sublamination of the internal pyramidal layer (V) ( Carmichael-1994 ). Some authors divide area 12 into only two parts, an orbital part and a lateral part ( Paxinos-2009a ).
Its human equivalent is area 47/12s ( Ongur-2003 ), which may be the same as area 47s ( Glasser-2016 ). As granular prefrontal cortex, it has no equivalent in the rat ( Wallis-2012 ).
Also known as: area 12o of Carmichael, area 12o, orbital area 12, area 12o (macaque)
