Mind of Blue: Conveying Emotion Affects Brain’s Creativity Network

January 14th, 2016

 

In a recent University of California, San Francisco study involving jazz pianists, according to the public release document associated with the research, neuroscientists have concluded that “the workings of neural circuits associated with creativity are significantly altered when artists are actively attempting to express emotions.”

The public release, entitled “Mind of Blue: Conveying Emotion Affects Brain’s Creativity Network,” reminds us that during the act of improvisation, a brain region known as the dorsolateral prefrontal cortex (DLPFC), which is “involved in planning and monitoring behavior” is deactivated, allowing the musician to enter into a “flow state” that artists enter to “free up creative impulses.”

The new study found that this deactivation “was significantly greater when the jazz musicians, who played a small keyboard while in the fMRI scanner, improvised melodies intended to convey the emotion expressed in a ‘positive’ image (a photograph of a woman smiling) than when they aimed to capture the emotions in a ‘negative’ image (a photograph of the same woman in a mildly distressed state). On the other hand, improvisations targeted at expressing the emotion in the negative image were associated with greater activation of the brain’s reward regions, which reinforce behaviors that lead to pleasurable outcomes, and a greater connectivity of these regions to the DLPFC.”

Malinda McPherson, an author of the study, writes that there is more “deactivation of the DLPFC during happy improvisations, perhaps indicating that people are getting into more of a ‘groove’ or ‘zone,’ but during sad improvisations there’s more recruitment of areas of the brain related to reward [which would indicate] there may be different mechanisms for why it’s pleasurable to create happy versus sad music.”

Senior research author Charles Limb, M.D. concludes that “the notion that we can study complex creativity in artists and musicians from a neuroscientific perspective is an audacious one, but it’s one that we’re increasingly comfortable with. Not that we’re going to answer all the questions, but that we have the right to ask them and to design experiments that try to shed some light on this fascinating human process.”

“The bottom line,” says Dr. Limb, “is that emotion matters.”

A Collection of Jazz Poetry — Winter, 2024 Edition...One-third of the Winter, 2024 collection of jazz poetry is made up of poets who have only come to my attention since the publication of the Summer, 2023 collection.

Interview with Tad Richards, author of Jazz With a Beat: Small Group Swing, 1940 – 1960...Richards makes the case that small group swing players like Illinois Jacquet, Louis Jordan (pictured) and Big Jay McNeely played a legitimate jazz that was a more pleasing listening experience to the Black community than the bebop of Parker, Dizzy, and Monk. It is a fascinating era, filled with major figures and events, and centered on a rigorous debate that continues to this day – is small group swing “real jazz?”

Jazz History Quiz #172

photo of Teddy Wilson by William Gottlieb
Teddy Wilson once said this about a fellow jazz pianist:

“That man had the most phenomenal musical gifts I’ve ever heard. He was miraculous. It’s like someone hitting a home run every time he picks up a bat. We became such fast friends that I was allowed to interrupt him anytime he was playing at the house parties in Toledo we used to make every night. When I asked him, he would stop and replay a passage very slowly, showing me the fingering on some of those runs of his. You just couldn’t figure them out by ear at the tempo he played them.”

Who is the pianist he is describing?
