Russell Foster: Why do we sleep? | Video on TED.com
Yes, I am pretty nocturnal at the moment, despite only having two hours sleep Friday morning and going OUTSIDE!!!!! and visiting our new niece that day. I know that my hypothalamus it very broken and I also know that, for me, sleeping when I am sleepy and so likely to be able to fall asleep is the only thing that works for me. I used to be semi-alcoholic at university - drink was the only thing that would make me able to sleep at night and I also needed alcohol to face the day and so I can also relate to that portion of his talk. The discussions of sleep, schizophrenia, bipolar and genetics are also of interest, especially given the recent findings about schizophrenia and MS being genetically linked (see my earlier post).
