supracallosal gyrus
Acronym:
SCG
The term supracallosal gyrus refers to a composite structure that, in the human, extends along the dorsal surface of the corpus callosum from the dentate gyrus and fasciolar gyrus caudally to the paraterminal gyrus rostrally. It consists of three longitudinal structures: the medial longitudinal stria, the indusium griseum and the lateral longitudinal stria ( Riley-1943 ). In the macaque ( Paxinos-2000 ), the rat ( Swanson-2004 ) and the mouse ( Hof-2000 ), the indusium griseum is identified largely by histology with stains for Nissl substance, and the longitudinal striae are not usually identified in brain atlases of those species. Thus, in those species the indusium griseum is the histological equivalent of the human supracallosal gyrus and is most often labeled simply ' indusium griseum '.
Also known as: supracommissural hippocampus
