  11. Quote from patient • “Dr O’Connor said ‘Karen what are you doing? Your hand’s undressing you’. Until he said that I had no idea that my left hand was opening up the buttons of my shirt. • “So I start rebuttoning with the right hand and, as soon as I stopped, the left hand started unbuttoning them. So he put an emergency call through to one of the other doctors and said, ‘Mike you’ve got to get here right away, we’ve got a problem’.”

  12. Quote from patient • “I’d light a cigarette, balance it on an ashtray, and then my left hand would reach forward and stub it out. It would take things out of my handbag and I wouldn’t realise so I would walk away. I lost a lot of things before I realised what was going on.”

  13. 2. Alien Hand Syndrome • One hand appears to take a mind of its own, making purposeful actions without conscious will • Examples: • You are told to push in a chair, so your right hand goes to reach for it. Your left hand knocks it over instead. • You are trying to flip to a certain page in a book. Your other hand closes the book instead.

  14. What is it caused by? • Damage to the corpus callosum • The non-dominant brain goes “alien” • Surgery, stroke, etc. • Can also be caused by damage to frontal/parietal lobes

  15. How can we explain Alien Hand Syndrome? • Scientific Question: What happens in the brain when we “decide” to do something, like move our hand?

  22. What is the prognosis and treatment? • Not curable • Contributes to problems like: depression, substance abuse, social problems, poverty, homelessness, suicide; - 12 years of life

  23. Synesthesia • http://www.wimp.com/experiencesynesthesia/

  24. 6. Synesthesia (A trait, not a disease or a disorder – nothing is “wrong” with these people” • When stimulation of one sense leads to automatic, involuntary experiences in another • Grapheme  Color • Sound  Color • Word  Taste • An exaggeration of our existing urges: • “loud shirt,” “bitter wind”

  25. Can you find the 6 number 2s? How long did it take you to find?

  26. When people with certain types of synesthesia look at the image on the left, they can easily detect the six figures facing the opposite way, as shown in the image on the right. To these people, the "S" figures appear in a different color than the "2" figure.
