FULL STORY ==========================================================================
A new study led by UCLA Health scientists shows highly creative people's
brains appear to work differently from others', with an atypical approach
that makes distant connections more quickly by bypassing the "hubs"
seen in non-creative brains.


========================================================================== Exceptionally creative visual artists and scientists -- called "Big C"
creative types -- volunteered to undergo functional MRI brain imaging,
giving researchers in psychiatry, behavioral sciences and psychology a
look at how regions of the brain connected and interacted when called
upon to perform tasks that put creative thinking to the test.

"Our results showed that highly creative people had unique brain
connectivity that tended to stay off the beaten path," said Ariana
Anderson, a professor and statistician at the Semel Institute for
Neuroscience and Human Behavior at UCLA, the lead author of a new article
in the journal Psychology of Aesthetics, Creativity, and the Arts. While non-creatives tended to follow the same routes across the brain, the
highly creative people made their own roads.

Although the concept of creativity has been studied for decades, little is known about its biological bases, and even less is understood about the
brain mechanisms of exceptionally creative people, said senior author
Robert Bilder, director of the Tennenbaum Center for the Biology of
Creativity at the Semel Institute. This uniquely designed study included
highly creative people representing two different domains of creativity
-- visual arts and the sciences -- and used an IQ-matched comparison
group to identify markers of creativity, not just intelligence. The
researchers analyzed how connections were made between brain regions
globally and locally.

"Exceptional creativity was associated with more random connectivity at
the global scale -- a pattern that is less 'efficient' but would appear
helpful in linking distant brain nodes to each other," Bilder said. "The patterns in more local brain regions varied, depending on whether people
were performing tasks.

Surprisingly, Big C creatives had more efficient local processing at rest,
but less efficient local connectivity when performing a task demanding 'thinking outside the box.'" Using airline route maps for comparison,
the researchers said the Big C creatives' brain activity is akin to
skipping flights to connecting hubs to get to a small city.

"In terms of brain connectivity, while everyone else is stuck in a
three-hour layover at a major airport, the highly creatives take private
planes directly to a distant destination," Anderson said. "This more
random connectivity may be less efficient much of the time, but the architecture enables brain activity to 'take a road less traveled' and
make novel connections." Bilder, who has more than 30 years' experience researching brain-behavior relations, said, "The fact that Big C people
had more efficient local brain connectivity, but only under certain
conditions, may relate to their expertise.

Consistent with some of our prior findings, they may not need to work
as hard as other smart people to perform certain creative tasks." The
artists and scientists in the study were nominated by panels of experts
before being validated as exceptional based on objective metrics. The
"smart" comparison group was recruited from participants in a previous
UCLA study who had agreed to be contacted for possible participation in
future studies, and from s in the community for individuals with graduate degrees. The researchers made efforts to ensure that age, sex, race and ethnicity were comparable to those of participants in the Big C groups.

In addition to Bilder and Anderson, authors include Kevin Japardi, a data intelligence analyst at Cedars-Sinai Medical Center; Kendra Knudsen,
a researcher in psychology at UCLA; Susan Bookheimer, a researcher
in psychiatry, behavioral sciences and psychology at UCLA; and Dara
Ghahremani, a researcher in psychiatry and behavioral sciences at UCLA.

The research was funded by a grant from the John Templeton Foundation
(42052) awarded to Robert Bilder, and by the Michael E. Tennenbaum Family Center for the Biology of Creativity.
