posterior cingulate gyrus

posterior cingulate gyrus (CGGp)

The term posterior cingulate gyrus (CGGp) 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 (CGGa) anteriorly and the isthmus of the cingulate gyrus (ICG) posteriorly.. Identified by dissection it is a prominent convolution on the mesial aspect of the cerebral hemisphere (CHS). In the human the CGGp is continuous rostrally with the CGGa. Their junction is located at about the level of the central sulcus (cns) and corresponds to the boundary in midcingulate cortex (MCC) between cytoarchitectural area 24 anteriorly and area 23 posteriorly ( Vogt-2012 ). The structure lies dorsal to the posterior one-third of the body of the corpus callosum (bcc), from which it is separated by the callosal sulcus (cas). It ends caudally at the splenium of the corpus callosum (scc) where it becomes continuous with the isthmus of the cingulate gyrus (ICG). In the depth of the cas, the supracallosal gyrus (SCG) partially intervenes between it and the corpus callosum (cc). It is separated from the postcentral gyrus (POG). rostrally by the cingulate sulcus (cgs) and separated from the precuneus (PCU) of the parietal lobe (PLB) caudally by the splenial sulcus (spls). Histologically it corresponds approximately to the combination of area 23 of the posterior cingulate cortex (PCC) and the retrosplenial cortex (RSC) ( Vogt-2012 ). The CGGp is not the same as the posterior cingulate cortex (PCC), which is defined on the basis of internal structure, connectivity and function ( Vogt-2012 ). The functionally defined PCC occupies only the caudal part of the CGGp; the remainder is occupied by midcingulate cortex (MCC). The junction with CGGa, which is unmarked topologically, is located at about the level of the central sulcus (cns) on the dorsal surface of the cerebral hemisphere (CHS) . It corresponds to the boundary in midcingulate cortex (MCC) between cytoarchitectural area 24 anteriorly and area 23 posteriorly ( Vogt-2012 ). Considerable confusion in the neuroscientific literature results from attribution of MCCa functions identified by noninvasive imaging to rostral parts the CGGp. In the macaque, the CGGp is similar to that of the human except that it occupies the posterior half the area dorsal to the body of the corpus callosum (bcc) ( Martin-2000 ), and the complexity of sulcal patterns is less pronounced ( Vogt-1987; Vogt-1995 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). Updated 31 Oct 2024.

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.
