Parts of brain regions cycle in and out of sleep, even when you're awake

S.O.T.T: When we're in a deep sleep, our brain's activity ebbs and flows in big, obvious waves. New research from Stanford has found that those same cycles exist when we're awake as well, with tiny portions of the brain independently falling asleep and waking back up all the time. The team used special super-sensitive probes that could record activity from a column of neurons in the brain. In the past, people had known that individual neurons go through phases of being more or less active, but with this probe the researchers saw for the first time that all the neurons in a given column cycled together between firing very rapidly then firing at a much slower rate, similar to coordinated cycles in sleep...read more>>>....
