external definition

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