limiting sulcus (crs)

The term limiting sulcus refers to the boundary between the cortex of the insula and that of surrounding gyri of the frontal lobe, the parietal lobe and the temporal lobe. Equally well known as the 'circular sulcus', it is identified by dissection in higher primates. In the human it has three parts: the anterior limiting sulcus, which separates the anterior insula from the basal operculum of the orbital gyri; the superior limiting sulcus, which separates the dorsal part of the insula from the frontal operculum and the parietal operculum; and the inferior limiting sulcus, which separates the insula ventrally from the superior temporal gyrus ( Ture-1999 ). The limiting sulcus of the macaque is similar except that it has no anterior component ( Mufson-1997 ). Equivalent structures are not found in the smooth cerebral cortex of the rat and mouse ( NeuroNames ).

Also known as: circular sulcus of the insula, circular sulcus of insula, Sulcus circularis insulae, circular sulcus (of Reil), circular insular sulcus, limiting fissure, circular fissure, circuminsular sulcus, marginal sulcus of insula, marginal insular sulcus, Sulcus marginalis insulae, periinsular sulci, circular sulcus, limiting sulcus, peri-insular sulcus, circuminsular 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.
