corpus callosum

Examples of corpus callosum in the following topics:

• Cerebral Hemispheres and Lobes of the Brain

  • The two hemispheres communicate with one another through the corpus callosum.
  • The corpus callosum is a wide, flat bundle of neural fibers beneath the cortex that connects the left and right cerebral hemispheres and facilitates interhemispheric communication.
  • The corpus callosum is sometimes implicated in the cause of seizures; patients with epilepsy sometimes undergo a corpus callostomy, or the removal of the corpus callosum.

• Psychosurgery

  • Corpus callosotomy is a palliative surgical procedure for the treatment of seizures, as seen in epilepsy.
  • Because the corpus callosum is critical to the spread of epileptic activity between brain hemispheres, the goal of this procedure is to eliminate this pathway.
  • The corpus callosum is severed, after which the brain has much more difficulty sending messages between the hemispheres, although some limited interhemispheric communication is still possible.

• Physical Development in Late Adulthood

  • The frontal lobe (which is responsible for the integration of information, judgement, and reflective thought) and corpus callosum tend to lose neurons faster than other areas, such as the temporal and occipital lobes.

• Theories of Multiple Intelligence

  • For example, Kim Peek is a savant who was born with considerable brain damage including an enlarged head, a missing corpus callosum (the fibers that connect the two hemispheres of the brain), and a damaged cerebellum.

• The Limbic System

  • The cingulate gyrus is located in the medial side of the brain next to the corpus callosum.
