Arthur T Knackerbracket has found the following story[1]:

Sleep is known to be important for creative thinking, but exactly how it
helps and what role each sleep stage -- REM and non-REM -- plays remains
unclear. A team of researchers have now developed a theory, outlined in an
Opinion published May 15 in the journal Trends in Cognitive Sciences, to
explain how the interleaving of REM and non-REM sleep might facilitate
creative problem solving in different but complementary ways.

"Suppose I give you a creativity puzzle where you have all the information
you need to solve it, but you can't, because you're stuck," says first author
Penny Lewis, a professor at the Cardiff University School of Psychology. "You
could think of that as you've got all the memories that you need already, but
you need to restructure them -- make links between memories that you weren't
linking, integrate things that you weren't integrating."

Studies show that this kind of restructuring often happens while we are
asleep, so Lewis and her co-authors drew on that literature, as well as
physiological and behavioral data, to create a model of what might be
happening during each stage. Their model proposes that non-REM sleep helps us
organize information into useful categories, whereas REM helps us see beyond
those categories to discover unexpected connections.

[...] "So, what we propose is that, if you're stuck on some kind of problem,
that problem is salient, and we know that salient things are replayed," Lewis
says. "The slightly hypothetical part is that, when something else is
randomly activated in the cortex that has an element that's similar, you'll
form a link." These surprising links may be the creative leaps required to
solve a problem.

Oh, and now these "researchers" are rediscovering the phrase "slept on
it."

How can I get a job as a test subject for this fascinating research?  I
could use a new job that involves more napping than the job I've got.
