rostral sulcus - BrainInfo

rostral sulcus (ros)

The term rostral sulcus refers to a superficial feature of the frontal lobe identified by dissection. In the human it is a horizontal groove on the lower medial surface that separates the straight gyrus below from the inferior rostral gyrus above ( Mai-1997 ); in brains that have parallel sulci dorsal to the straight gyrus, it is called the inferior rostral sulcus ( Vogt-1995 ). In the macaque, which does not have an inferior rostral gyrus or a superior rostral gyrus, it separates the straight gyrus from the anterior cingulate gyrus ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: rostral sulcus, Sulcus rectus (Krieg), sulcus rectus, inferior rostral sulcus, Sulcus rostralis inferior

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.
