If you are left handed, reverse this.

Although we posted recently we stumbled across a little psychological study that we found intriguing and thought we would share with you. While you are reading this we would like to point out that you may not be alone. Perhaps someone else is reading this also, someone sitting right there with you. Actually someone sitting in your exact spot and looking through your eyes. In 1908 a woman was brought to a psychologist because she had a problem, it seemed her left hand had a nasty temper, and a murderous nature. It would try to strangle her during the night. Normally she was a quiet woman of even temper, but when she slept, and sometimes when she was awake her left hand would suddenly lash out and attack people, seemingly at random. Many people of the time believed her hand had become possessed by the devil. The Doctor could find nothing wrong with the woman, and although she had recently had a stroke she seemed to be fully recovered. It wasn't until years later, when she had died of natural causes that the Doctor removed her brain and found that the stroke had damaged her corpus callosum (The area between the two halves of the human brain.) Unfortunately there was no way to prove that it was that injury which caused her hand to seemingly have a mind of it's own.  It wasn't until 1972 that Doctors were able to verify that yes "Alien hand syndrome." does exist. What makes the illness (if that's what you can call it) so strange is that the hand doesn't just randomly move, it seems to have intent. One mans hand insisted on grabbing his collar and shaking him awake in the middle of the night. (It wasn't until he put an oven mitt on it while he slept that the hand stopped.) In one case if food was present at the table the man's hand would attempt to feed him. (Another mans hand attempted to masturbate, no matter where the man was at the time.) The reasons for alien hand syndrome (some people are calling it Doctor Strangelove Syndrome, anyone who has seen the movie should be able to figure out why.) are clear, a separation or damage of the corpus callosum, unfortunately that doesn't explain why the hand has a mind of it's own. Although people who have brain damage in other areas of the brain can have problems with hands acting on their own, it seems only the separation of the lobes of the brain causes clear seemingly conscious action by the left hand. And that is a puzzle, is there a separate distinct personality in each lobe of the brain? Is this why some people are unable to control their baser instincts? Are we ALL schizophrenic? That's about it for now. Keep an eye on your hands. (Especially that left one, it can be a sneaky little thing) Ciao for now.

  1. While reading this post I immediately thought of 'Dr. Strangeglove' and was pleased that you mentioned it towards the end. I believe we still only understand a fraction of the human brains' nuances - maybe less if you consider the unconscious aspect of the mind and/or dreams. I always tell people that my hand is possessed by another brain when I constantly 'flip off' bad drivers (well maybe not so much).

  2. I agree, it seems that the human mind is much more than the sum of it's parts. And even after years of study and experiment, we seem to know so little about it's inner workings. Consciousness itself is a mystery.
