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.
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.
The corpus callosum is essential to the communication between the two hemispheres. [2] A recent study of individuals with agenesis of the corpus callosum suggests that the corpus callosum plays a vital role in problem solving strategies, verbal processing speed, and executive performance. Specifically, the absence of a fully developed corpus ...
The corpus callosum is a fiber bundle of about 300 million fibers in the human brain that connects the two cerebral hemispheres. Its interhemispheric functions include the integration of perceptual, cognitive, learned, and volitional information. [12]
Agenesis of the corpus callosum (ACC) is a rare birth defect in which there is a complete or partial absence of the corpus callosum. It occurs when the development of the corpus callosum, the band of white matter connecting the two hemispheres in the brain , in the embryo is disrupted.
Although the left and right hemispheres are broadly similar in shape and function, some functions are associated with one side, such as language in the left and visual-spatial ability in the right. The hemispheres are connected by commissural nerve tracts, the largest being the corpus callosum.
When the corpus callosum is missing or not formed properly, it can lead to many dysfunctions throughout the body including hypothermia and hyperhidrosis. [4] Agenesis of the corpus callosum has been found in 40% of Shapiro syndrome cases reported. [4] It is theorized that Shapiro syndrome develops based on genetic factors. [1]
