external definition

The largest commissure of the brain connecting the cerebral hemispheres. [TFD][VHOG]

homology notes

In addition to the anterior commissure, placental mammals have a phylogenetically new forebrain commissure, the corpus callosum, which primarily interconnects the neocortex of the cerebral hemispheres.[well established][VHOG]



taxon notes

The corpus callosum is found only in placental mammals. other groups do have other brain structures that allow for communication between the two hemispheres, such as the anterior commissure, which serves as the primary mode of interhemispheric communication in marsupials.
