Study: Sleep essential c
for creative thinking
By William McCall
THE ASSOCIATED PRESS
‘Let me sleep on It’
Rolling Stones guitarist
Keith Richards said the riff in
“(I Can’t Get No) Satisfaction”
came to him in his sleep, while
the 19th-century chemist Dmitri
Mendeleev literally dreamed up
the periodic table of elements.
Now, for the first time, sci
entists say they have proved
what creative minds have
known all along: that our
sleeping brains continue work
ing on problems that baffle us
during the day, and that the
right answer may come more
easily after eight hours of rest.
The German study is consid
ered to be the first hard evidence
supporting the common sense
notion that creativity and prob
lem-solving appear to be direct
ly linked to adequate sleep.
Some researchers said the
study provides a valuable
reminder for overtired workers
and students that sleep is often
the best medicine.
“A single study never settles
an issue once and for all, but 1
would say this study does
advance the field significantly,"
said Dr. Carl E. Hunt, director of
the National Center on Sleep
Disorders Research at the
National Institutes of Health.
German researchers have
discovered that creativity and
problem-sotving are directly linked
to the transfer of memories during
deep sleep. Scientists believe
memories start in an area of the
brain called the hippocampus, and
are eventually pushed outward to
the neocortex to be consolidated.

“It’s going to have potentially
important results for children for
school performance and for
adults for work performance.”
Scientists at the University of
Luebeck found that volunteers
taking a simple math test were
three times more likely than
sleep-deprived participants to
figure out a hidden rule for con
verting the numbers into the
right answer if they hadet
hours of sleep. The findt
appear in Thursday’s issue
the journal Nature.
Jan Bom, who led
study, said the results supp
