Thank you very much.
You've opened up a much larger window, and that is it was largely with the support of DCIEM and DRDC that I was privileged to get into this area in 1980. I was interested in precisely what is going on in the brain as it links to the immune system. At that time no one believed there was any linkage. We went ahead and showed that there was, and that there are hormones of the immune system that put us to sleep and wake us up. The reason we're all here today is that all these things are working automatically, and we don't have to think about them, but if we start to screw around with our sleep, they don't function.
The work that I pioneered in with colleagues in Toronto led me to work with the Canadian Space Agency and in turn with NASA and the Russian space agency because we became interested in long-term survival in the most adverse circumstances over a long period of time. We learned a lot and showed that disruption of sleep in the cosmonauts and astronauts was linked to hormones that would be associated with inflammation and infection. They didn't have it, but they were vulnerable.
Although I'm not doing that now because I'm emeritus, I've been focusing on the sleep-wake physiology aspects. I'm leaving it to my colleagues to come up with novel things, and I'm hopeful that we can collaborate.
