00:02:42 Researchers say being deprived of sleep, even for one night, makes the brain unstable and prone to sudden shutdown. The University of Pennsylvania School of Medicine study found that people who are sleep deprived alternate between periods of near normal brain function and dramatic collapses in attention and visual processing. 00:05:42

[CC] 00:55:57 New research says that losing just one night of sleep could cause your brain to experience sudden shutdown. The University of Pennsylvania says missing sleep causes mental power failures, making it hard to perform simple tasks and remember things. 00:58:57

00:02:24 Researchers say if you are deprived of sleep, even for just one night, can it make the brain unstable and prone to sudden shutdowns. The University of Pennsylvania study describes it as if a person is both asleep and awake, switching between each other very rapidly. The Journal of NeuroScience published the study. 00:05:24

[CC] 00:08:31 This is interesting, did you ever lose a night's sleep? No matter what you tried, you couldn't fall asleep, and the next morning you had to go to work anyway. According to a study done by a researcher at the University of Pennsylvania, being deprived of sleep for even one night makes the brain unstable, and prone to sudden shut downs, akin to a power failure. 00:11:31

00:03:22 A study done by David Degense and his colleagues at the University of Pennsylvania School of Medicine involved adults who were asked to perform simple tasks involving visual attention. Each of them did the same tasks when they were well rested, and again when sleep deprived. They used FMRI during tests. There were lapses in several areas of the brain. It didn't occur when they were well rested. 00:06:22
