isthmus of the cingulate gyrus

isthmus of the cingulate gyrus (ICG)

The term isthmus of the cingulate gyrus (ICG) refers to one of three components of the cingulate gyrus (CGG) in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). The others are the anterior cingulate gyrus (ACG) and the posterior cingulate gyrus (PCG). Identified by dissection it is a small convolution on the mesial aspect of the cerebral hemisphere (CHS). In curving around the splenium of the corpus callosum (ccs) it connects the PCG dorsally and with the parahippocampal gyrus (PHG) ventrally. In some cases it is partially separated from the PHG by the anterior calcarine fissure (clfa), which also separates it from the lingual gyrus (LNG) caudally ( Duvernoy-1992 ). Its location in the macaque is similar except that its caudal boundary is with the cuneus (CUN) and is less well defined ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex (CTX) of the rat or mouse ( NeuroNames ). Updated 30 Oct 2024.

Also known as: isthmus of the cingulate gyrus, isthmus of cingulate gyrus, Isthmus gyri cinguli, Isthmus gyri cingulatus, Isthmus cinguli, isthmus of fornicate gyrus, isthmus of limbic lobe, Isthmus-2, Isthmus of Gyrus fornicatus, isthmus

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.
