The term cingulate gyrus (CGG) refers to one of four components of the limbic lobe (LLB) in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). The others are the parahippocampal gyrus (PHG), the hippocampus (HPP), and the subcallosal gyrus (SCL). Identified by dissection, the CGG is a prominent convolution on the mesial aspect of the cerebral hemisphere (CHS). It is separated from the corpus callosum (cc) ventrally by the callosal sulcus (cas). In the depth of the sulcus the supracallosal gyrus (SCG) partially intervenes between it and the cc. Dorsally the CGG is separated from the frontal lobe (FLB) and part of the parietal lobe (PLB) by the cingulate sulcus (cgs). The splenial sulcus (spls) separates it from the ramainder of the precuneus (PCU) caudally. It is composed of three parts: the anterior cingulate gyrus CGGa), the posterior cingulate gyrus (CGGp) and the isthmus of the cingulate gyrus (ICG).. In the macaque, the CGG is the same except for less complexity of sulcal patterns than in the human ( Vogt-1995 Vogt-1987 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). Updated 31 Oct 2024.
