One of the worst things that has happened recently, with budgets being what they are, is the elimination or cutting of musical programs in schools. Studies show that music enhances brain activity and makes other disciplines easier to digest and learn. My friend, Ken McPherson sent me this link:
WASHINGTON (AP) — Scientists inspired by the legendary improv of Miles Davis and John Coltrane are peering inside the brains of today's jazz musicians to learn where creativity comes from. Think dreaming.
This isn't just a curiosity for jazz fans but a bold experiment in the neuroscience of music, a field that's booming as researchers realize that music illuminates how the brain works. How we play and hear music provides a window into most everyday cognitive functions — from attention to emotion to memory — that in turn may help find treatments for brain disorders.
Creativity, though, has long been deemed too elusive to measure. Saxophonist-turned-hearing specialist Dr. Charles Limb thought jazz improvisation provided a perfect tool to do so — by comparing what happens in trained musicians' brains when they play by memory and when they riff....
Then they put six professional jazz pianists inside to measure brain activity while they played straight and when they improvised. They played, right-handed, both a simple C scale and a blues tune that Limb wrote, appropriately titled "Magnetism." Through earphones, they listened to a prerecorded jazz quartet accompaniment, to simulate a real gig.
Getting creative uses the same brain circuitry that Braun has measured during dreaming: First, inhibition switched off. The scientists watched a brain region responsible for that self-monitoring, the dorsolateral prefrontal cortex, shut down.
Then self-expression switched on. A smaller area called the medial prefrontal cortex fired up, a key finding as Braun's earlier research on how language forms linked that region to autobiographical storytelling. And jazz improvisation produces such individual styles that it's often described as telling your own musical story.
More intriguing, the musicians also showed heightened sensory awareness. Regions involved with touch, hearing and sight revved up during improv even though no one touched or saw anything different, and the only new sounds were the ones they created.
That doesn't necessarily mean this is the center of creativity. The brains of highly trained musicians might work differently than an amateur pianist's, or a painter's, or a writer's, something Limb and Braun hope to test next.
"We're all creative every day. Are our brains doing the same things?" asks Braun, who studies the relationship of language and music at NIH's National Institute on Deafness and Other Communication Disorders.
The study's biggest significance isn't what it found but that it could be performed at all, opening new avenues of brain research.
"Improvisation always has a sort of magical quality associated with it. People think when you're improvising you have some sort of inspiration that's not measurable," says Dr. Robert Zatorre of the Montreal Neurological Institute, a pioneer in the neuroscience of music and himself a classical organist. "They went forward where everyone else feared to tread."
Neuroscientists call the brain plastic, meaning it has remarkable flexibility to rewire itself. Unraveling how those circuits get modified in turn helps researchers hunt treatments for brain disorders — and the same circuits that process music show strong relationships with other key brain regions. Studies show that patients learning to speak again after a stroke may improve faster if they sing rather than recite, for example. Zatorre's team is finding parallels between tone-deafness and the reading disability dyslexia.
"What we're doing is not necessarily trying to say, 'Well, if we use music it will help Parkinson's patients walk.' It might, yes, and there is some evidence it does so," says Zatorre, whose institute this summer hosts an international conference on music and the brain.
Instead, the quest is to "understand the rules by which the brain changes its organization. That's what we need to know," he adds.
Creativity comes in because its root is the spontaneity that defines everyday life. Consider conversation: Hopkins' Limb wants to image the brains of jazz musicians "trading fours," where one improvises four bars and the next answers back with four new bars — a musical conversation he believes comparable to the talking kind.
And no, Limb doesn't think he's diminishing the magic of music by finding its cerebral underpinnings.
"It's like knowing how an airplane flies. It's still pretty magical."
