area 10 (10)
The term area 10 refers to an area occupying the transverse frontopolar gyri, the most rostral portion of the orbital gyri and the rostral two thirds of the straight gyrus of the frontal lobe in the human. It is granular prefrontal cortex. Subdivided on the basis of multiple stains it has three subdivisions: area 10p, area 10r, and area 10m ( Ongur-2003 ). Subdivided on the basis of multiple other criteria it has six subdivisions: 1) area 10d and area 10pp corresponding to the medial part of area 10p, 2) area a10p and area p10p corresponding to the lateral part of area 10p; and 3) area 10v and area 10r of Glasser forming the equivalent of area 10m and area 10r ( Glasser-2016 ). .
The equivalent architectonic area in the macaque occupies banks of the rostral sulcus and rostral parts of the orbital gyri and the superior frontal gyrus at the frontal pole. In the macaque it has only two subdivisions: area 10o, which is topologically equivalent to the orbital part of area 10p in the human, and area 10m of Carmichael, which is equivalent to the rest of area 10p, area 10r and area 10m in the human.
As granular prefrontal cortex, area 10 has no equivalent in the rat ( Wallis-2012 ).
