Apparently I am thoroughly sick of writing about academic topics this summer, so let's talk, or link to articles about, brains--sweet, nourishing brains.
"So far, this study—which has examined 13 creative
geniuses and 13 controls—has borne out a link between mental illness and
creativity similar to the one I found in my Writers’ Workshop study. The
creative subjects and their relatives have a higher rate of mental illness than
the controls and their relatives do (though not as high a rate as I found in
the first study), with the frequency being fairly even across the artists and
the scientists." I would only
say that, from talking to people who have worked in psychiatric wards, the
reverse is not necessarily true: madness does not necessarily mean creativity.
- "Why Your Brain Needs More Downtime" from Scientific American (and can't we all say a big "amen" to that?). Not only does the brain like to laze around from time to time, but it's a hearty eater:
By the mid 1990s, however, Marcus Raichle of Washington
University in Saint Louis and his colleagues had demonstrated that the human
brain is in fact a glutton, constantly demanding 20 percent of all the energy
the body produces and requiring only 5 to 10 percent more energy than usual
when someone solves calculus problems or reads a book. . . . Related research suggests that
the default mode network is more active than is typical in especially creative
people, and some studies have demonstrated that the mind obliquely solves tough
problems while daydreaming—an experience many people have had while taking a
shower. Epiphanies may seem to come out of nowhere, but they are often the
product of unconscious mental activity during downtime.
"This is Your Brain on Writing" at The New York Times. This one gives a big implicit push to the idea that if you write every day, like a professional writer, you'll actually access different parts of your brain than a novice.
As the scientists report in a new study in the journal
NeuroImage, the brains of expert writers appeared to work differently, even
before they set pen to paper. During brainstorming, the novice writers
activated their visual centers. By contrast, the brains of expert writers showed
more activity in regions involved in speech.
“I think both groups are using different strategies,” Dr.
Lotze said. It’s possible that the novices are watching their stories like a
film inside their heads, while the writers are narrating it with an inner
voice.
When the two groups started to write, another set of
differences emerged. Deep inside the brains of expert writers, a region called
the caudate nucleus became active. In the novices, the caudate nucleus was
quiet.
The caudate nucleus is a familiar part of the brain for
scientists like Dr. Lotze who study expertise. It plays an essential role in
the skill that comes with practice, including activities like board games.
- Scientific American's blog informs us that there is no such thing as right brain/left brain activity:
In a recent large review, Rex Jung and colleagues provide a
“first approximation” regarding how creative cognition might map on to the
human brain. Their review suggests that when you want to loosen your
associations, allow your mind to roam free, imagine new possibilities, and
silence the inner critic, it’s good to reduce activation of the Executive
Attention Network (a bit, but not completely) and increase activation of the
Imagination and Salience Networks. Indeed, recent research on jazz musicians
and rappers engaging in creative improvisation suggests that’s precisely what
is happening in the brain while in a flow state.
And because I can never let this alone as a topic, a reprise of "What's Lost as Handwriting Fades" at the New York Times:
But psychologists and neuroscientists say it is far too soon
to declare handwriting a relic of the past. New evidence suggests that the
links between handwriting and broader educational development run deep.
Children not only learn to read more quickly when they first
learn to write by hand, but they also remain better able to generate ideas and
retain information. In other words, it’s not just what we write that matters —
but how.
“When we write,
a unique neural circuit is automatically activated,” said Stanislas Dehaene, a
psychologist at the Collège de France in Paris. “There is a core recognition of
the gesture in the written word, a sort of recognition by mental simulation in
your brain.
“And it seems that this circuit is contributing in unique
ways we didn’t realize,” he continued. “Learning is made easier.

This is really interesting stuff! But I also recently read an article that suggest that psychiatry's claims have not been borne out in terms of research and treatment (as well as the "chemical imbalance" theory), so this has made me wonder whether the markers of mental illness we're used to looking for are actually inaccurate.
Earnest English, good point. It may be that the interpretation of mental illness changes over time, so the markers change, too.
