superior precentral sulcus

superior precentral sulcus (sprs)

The term superior precentral sulcus refers to a superficial feature identified by dissection in the frontal lobe. It is located on the dorsal surface and, in the human, separates the precentral gyrus caudally from the superior frontal gyrus and the upper part of the middle frontal gyrus rostrally ( Duvernoy-1992 ). It should not be confused with the superior precentral dimple of the macaque. Sometimes referred to as a sulcus ( Szabo-1984 ), the dimple is a very short horizontal groove embedded in the precentral gyrus of that species ( Paxinos-2009a ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse.

Also known as: superior precentral sulcus, Sulcus praecentralis superior, superior part of precentral fissure

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.
