Anatomyand Physiology- Corpus Callusum
Acorpus callosum is a group of fibers of the nervous system that existin the brain. These fibers connect the two hemispheres of the brain.This band is responsible for the transmission of the informationbetween the two halves. Besides, it also helps in spreading ofseizure impulses from one-half of the brain to the other. A corpuscallosotomy is a form of surgery that involves the cutting of thecorpus callosum. The operation interrupts the spread of seizures fromone-half to the other. Although the seizures do not completely stopafter the surgery, the severity becomes less since they cannot bepassed to the other part of the brain and only continues on the sideof the brain, from which they originate. However, the process haseffects on the nervous, motor and the sensory systems.
Inthe neurological aspect, research indicates that there is thefunctional restructuring of the nervous system as a way ofcompensating for the lost or the thinned segments of the corpuscallosum. Nevertheless, the most common complications from theprocess are related to speech irregularities and the inability todetect items using the left hand. One can also fail to writealphabetical letters using the left hand. The surgery can be followedby a short period of being mute. Other symptoms include the visualfield dyslexia in the left side, ideomotor dyspraxia of the upperleft limb, anomia of the left hand, optical ground dysnomia of theleft side and the suppression of the left ear in the process ofdichotic listening challenges. The National Institute of Healthasserts that indeed the posterior part of the corpus callosum plays acritical role in connecting the visual and the motor responses.
