cingulate sulcus
Acronym: cgs
The term cingulate sulcus refers to a deep longitudinal cleft separating the limbic lobe from the frontal lobe and rostral portion of the parietal lobe in primates. Defined by dissection, it parallels the genu of the corpus callosum and the body of the corpus callosum. In the human it separates the cingulate gyrus from the superior frontal gyrus dorsal to the body and rostral to the genu. Caudally it separates the cingulate gyrus from the paracentral lobule, finally curving upward to define the boundary between the lobule and the precuneus ( Carpenter-1983 ).
     In the macaque also, it separates the cingulate gyrus from the superior frontal gyrus rostrally; continuing caudally it separates the cingulate from the medial surfaces of the precentral gyrus, the postcentral gyrus and the superior parietal lobule ( Martin-2000 ).
     Comparable structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
