According to new research, jazz musicians unconsciously switch off regions of the brain involved in self-censorship and firing up the area linked to self-expression. The scientists from Johns Hopkins University and the National Institute on Deafness and Other Communications Disorders used fMRI to scan the brains of jazz musicians as they played a specially-designed piano keyboard.Sounds cool. Here's a little from the scientists' press release:
The scientists found that a region of the brain known as the dorsolateral prefrontal cortex, a broad portion of the front of the brain that extends to the sides, showed a slowdown in activity during improvisation. This area has been linked to planned actions and self-censoring, such as carefully deciding what words you might say at a job interview. Shutting down this area could lead to lowered inhibitions, (professor Charles) Limb suggests.Read the whole thing. (It's interesting to note that Dr. Limb is himself a trained jazz saxophonist.)
The researchers also saw increased activity in the medial prefrontal cortex, which sits in the center of the brain’s frontal lobe. This area has been linked with self-expression and activities that convey individuality, such as telling a story about yourself.
“Jazz is often described as being an extremely individualistic art form. You can figure out which jazz musician is playing because one person’s improvisation sounds only like him or her,” says Limb. “What we think is happening is when you’re telling your own musical story, you’re shutting down impulses that might impede the flow of novel ideas.”
Limb notes that this type of brain activity may also be present during other types of improvisational behavior that are integral parts of life for artists and non-artists alike. For example, he notes, people are continually improvising words in conversations and improvising solutions to problems on the spot. “Without this type of creativity, humans wouldn’t have advanced as a species. It’s an integral part of who we are,” Limb says.
What's in a name? It's been an interesting few weeks for unusual names out here in Kev-land. In that time, I've been waited on by a server named "Mermaid," bought gas from a convenience store with a manager named "Babyline," and read something on one of my listservs posted by a "Coravious Cowart" (which just has "Harry Potter character" written all over it, doesn't it?).
