Large, C-shaped structure that contains most of commissural tracts of the brain is Corpus callosum. The corpus callosum is composed of four different neural pathways that connect various regions.
The main and greatest commissural tract that joins the right and left cerebral hemispheres is called the corpus callosum. This commissural channel may not form properly during embryonic development, resulting in split brain effect, a congenital disorder where the two hemispheres of the brain are not connected. The corpus callosum, which contains the majority of the brain's commissural fibres, is an important conduit for speech-language activities. The rostrum, genu, trunk or body, and splenium are these. Between the trunk and the spleen is a narrow region known as the isthmus.
