Contralateral and the Corpus Collosum

  (This image is from here.)

      The corpus collosum is a bundle of fibers that connects the left and right hemisphere of the brain.  There are surgeries that cut the corpus collosum which are called split-brain surgery and this is done with patients that have severe epilepsy. After this surgery takes place, there are still moments of epilepsy, but they are decreased.
      Contralateral control means opposite side; for example, the right hand is controlled by the left hemisphere of the brain.  The corpus collosum passes information from the left side of the brain to the right side of the brain, and vice versa.  For those that are left-handed, sometimes there is crossover between the left and right hemisphere, especially with language and writing. The left hemisphere is responsible for language, and the right hemisphere is responsible for the intonation within language; which would mean that the right hemisphere is able to detect sarcasm, upward inflections, and so on. The right hemisphere is also responsible for images, as in visualizing the face on a coin. Linguistic thinking is thought to be originated in the left hemisphere.
     The most amazing aspect of contralateral control is that when someone is being asked a question, depending on the type of question, there eyes will move in the direction that is opposite to the hemisphere that is being activated. So, if you the eyes move to the left, then the right hemisphere is being activated, and if you moves your eyes to the right after being asked a question, then the left hemisphere of your brain is being activated. That bit of information should be fun to try on your friends!!!
       The right hemisphere is able to "appreciate" music and see things holistically, while the left hemisphere see things in an analytical manner.  The picture below shows some key differences between the left and right hemisphere. So, please take a moment to look at the image below.
