frontal pole
Acronym:
FRP
The term frontal pole (FRP), defined topologically by dissection, refers to the rostral-most part of cerebral cortex (CTX) in the human ( Mai-1997 ). Seen largely on the mesial surface of the frontal lobe (FLB), it extends from the rostral tip of the lobe to the onset of unnamed sulci that separate the middle frontopolar gyrus (FPGm) from the superior frontopolar gyrus (FPGs) and the inferior frontopolar gyrus (FPGi). Laterally, the frontomarginal sulcus (fms) defines its boundary with the frontomarginal gyrus (FMG).
The FRP is not found in the macaque ( Martin-2000 ), rat ( Swanson-2004 ) or mouse ( Hof-2001 ). It is roughly equivalent to frontopolar cortex (PFCfp) in functional models.
In all species, fincluding the human ( Carpenter-1983 ), macaque ( Martin-2000 ), rat ( Swanson-2004 ), and mouse ( Hof-2000 ), the term 'frontal pole' (fpl) is also commonly applied to the rostral tip of the CTX as a surface feature of the FLB. Updated 25 Mar 2025.
