The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals . [ 1 ]
It is the most common cancer that begins within the brain and the second-most common brain tumor, after meningioma, which is benign in most cases. [6] [15] About 3 in 100,000 people develop the disease per year. [3] The average age at diagnosis is 64, and the disease occurs more commonly in males than females. [2] [3]
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.

Spastic tetraplegia, thin corpus callosum, and progressive microcephaly (often referred to by its acronym SPATCCM) is a rare autosomal recessive disease caused by mutations in the SLC1A4 gene encoding the ASCT1 protein. The ASCT1 protein is primarily found in astrocytes in the brain where its main role is to import L-serine, a non-essential ...

An example is commissural disconnect in adults which usually results from surgical intervention, tumor, or interruption of the blood supply to the corpus callosum or the immediately adjacent structures. Callosal disconnection syndrome is characterized by left ideomotor apraxia and left-hand agraphia and/or tactile anomia, and is relatively rare.
