The term area 10d (10d) refers to a functionally identified part of cerebral cortex (CTX) at the frontal pole (frp) in the human ( Glasser-2016 ). Topologically it is located in the superior frontopolar gyrus (FPGs) of the frontopolar area (FPA) ( Mai-1997 ). Histologically it is entirely part of the granular cortical area 10p of area 10 ( Ongur-2003 ). It greatly overlaps areas referred to by other authors as Fp1 and Fp2 ( Glasser-2016 ). A histological equivalent of Area 10d is not found in the macaque ( Carmichael-1994 ) nor in the the rat or mouse ( Wise-2008 ). Area 10d is fMRI-deactivated in GAMBLING tasks. Updated 11 Sep 2024.
