inferior precentral dimple

The term inferior precentral dimple refers to a depression in the precentral gyrus of the macaque ( Krieg-1975 ). While some authors refer to it as the anterior subcentral sulcus ( Szabo-1984; Martin-2000 ), it differs from that sulcus in the human by lack of connection to the lateral fissure. The structure in the macaque is in closer proximity to the central sulcus than to the lateral fissure. Equivalent features are not seen in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: anterior subcentral sulcus, anterior subcentral dimple, subcentral dimple, inferior precentral dimple

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.
