frontal pole - BrainInfo

frontal pole (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.

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
