Sleep Deprivation Increases Brain Activity

SL33Z3 writes "Researchers at the University of California at San Diego have found increased brain activity in areas of the brain that otherwise stay inactive. The longer the students went without sleep, the more activity was found. Research found students to have better recollection after long periods of sleep deprivation. Check out the release here. " Heck, combine this with the news about caffeine and I'm all set!

Post wrong?

My interpretation of the article is somewhat different than that of the poster. I think that the following line does NOT mean that "Research found students to have better recollection after long periods of sleep deprivation"

Although subjects' memory performance was less efficient with sleep deprivation, greater activity in the parietal region was associated with better memory.

My interpretation of that line is that, overall, students had WORSE memory performance when sleep-deprived, but those students who had greater activity in the parietal region performed better than those with lower activity -- but still worse than they would have had with a good night's sleep. Am I correct in my reading?

Sleep Deprivation can also kill.

Sleep deprivation can also kill you. I did a 12 page report on sleep and its effects on the human body, and have about 5 pages of stuff on sleep deprivation. A guy in the 1950's, I believe, did a radio show for 200 hours straight, and suffered SEVERE mental damage from it. Also, rats who have been deprived of any rest at all have died after 17 days. People with fatal familial insomnia, which causes the victim to be deprived of sleep for months upon months, will eventually kill after 9 to 12 months. If you want more information on sleep, deprivation, and disorders, e-mail me at mcnamarc@kirtland.cc.mi.us and I'll send you the report. I'll feel special, too. : )
