subcallosal gyrus
Acronym: SCG
The term subcallosal gyrus refers to a part of the limbic lobe of cerebral cortex defined on the basis of topology in the human. It is located rostral to the narrow paraterminal gyrus, ventral to the anterior cingulate gyrus and caudal to the superior frontal gyrus and straight gyrus. The nomenclature for this cortical region of the human is unusually confused ( Anthoney-1994 ). In accord with the principle of naming cortical volumetric structures defined by dissection as gyri, lobules etc. and those defined by internal structure as areas, regions etc., NeuroNames adheres to the definition of Broca as cited in Carpenter-1983.
     It is found in the macaque ( Vogt-1987 ), but not the rat or mouse, which do not have sulcal landmarks. The rat has a genu of the corpus callosum, but the area below it is occupied by the indusium griseum, a component of archicortex, not of cingulate cortex ( Swanson-2004 ). The mouse has no cortical area ventral to the genu ( Hof-2000 ).
