Rest & Sleep Not Enough

Resting and Sleeping alone is not enough to rest the mind, this story suggests. Some interesting snippets from the article:

“There is a huge amount of activity in the [resting] brain that has been largely unaccounted for,” says Marcus Raichle, a neuroscientist at Washington University in St Louis.

The fact that the brian is unable to “switch off” when not working on mental tasks is an intriguing research question. This article is an interesting read.

Another relevant snippet:

“Sokoloff, a researcher at the University of Pennsylvania in Philadelphia, … … expected his volunteer’s brain to guzzle more oxygen as it crunched the problems, but what he saw surprised him: his subject’s brain consumed no more oxygen while doing arithmetic than it did while he was resting with his eyes closed.”
