supracallosal gyrus
Acronym: SPG
The term supracallosal gyrus (SPG) refers to a very small composite structure defined by dissection, which, in the human, extends along the dorsal surface of the corpus callosum (cc) from the dentate gyrus.(DNG) and fasciola cinerea FSC caudally to the paraterminal gyrus (PTG) rostrally. It consists of three longitudinal structures: the medial longitudinal stria (mls), the indusium griseum (IDG) and the lateral longitudinal stria (lls) ( Riley-1943 ).
      In the macaque ( Martin-2000 ) it is similarly located. It is not present in the smooth cortex of the rat and mouse. In those species the IDG is embedded in cingulate cortex (CGX) where it is defined histologically ( Swanson-2004; Hof-2000 ). Final 22 Dec 2024.
