Summary: Research highlighted by Karen Barrett of the Institute for Health & Aging at the University of California, San Francisco (UCSF) shows that musical improvisation engages brain networks differently than playing memorized music.
Building on foundational neuroimaging work by Charles Limb, studies show that when experienced jazz musicians improvise, they reduce activity in the dorsolateral prefrontal cortex—dampening self-monitoring and criticism—and increase activity in the medial prefrontal cortex, a region linked to personal expression. Recent functional MRI work with children suggests that even without formal training, young improvisers display broad patterns of sensory deactivation along with distinct engagement of reward systems. Together, these findings imply that raw generative creativity and the “beginner’s mind” are fundamental features of human neural function rather than abilities gained only through extensive training.
Key Facts
- Prefrontal cortex modulation in adults: Expert jazz musicians show decreased dorsolateral prefrontal activity during improvisation (related to lowered self-monitoring) and increased medial prefrontal activity associated with self-expression and internal narrative.
- Generative neural networks: Improvisation recruits a multimodal network that spans auditory, motor, emotional, visual and proprioceptive brain regions, reflecting the complex, generative nature of creative music-making.
- Child development and raw creativity: In children learning to improvise, fMRI scans reveal broad deactivation across sensory hubs, suggesting early developmental stages of the creative networks seen in adults.
- Reward system engagement: Unlike simple scale practice, spontaneous improvisation in children more strongly activates subcortical reward structures, indicating that creating on the spot can be inherently pleasurable for young brains.
- Innate capacity: Distinct neural signatures observed during child improvisation support the idea that the capacity for creativity is embedded in basic brain architecture, not only a product of years of training.

Research shows that improvisation and creativity are beneficial for the brain.
In an episode of the Greater Good Science Center’s “Science of Happiness” podcast, host Shuka Kalantari spoke with Karen Barrett about what happens in the brain during musical improvisation. Barrett, an assistant professor in the UCSF Institute for Health & Aging, studies how music affects aging, brain health and behavior.
Shuka Kalantari: What drew you to improvisation?
Karen Barrett: I grew up in a musical household: my father was a scientist and classical guitarist and my mother played piano. I started piano at five and later double-majored in music and neuroscience in college. After graduate study in piano performance, I pursued a Ph.D. in music cognition to combine music and brain science. During my postdoc at UCSF I worked with Charles Limb, a jazz musician and innovator in studying improvisation. I found improvisation both magical and challenging—an experience that has also made me less rigid about mistakes and more open to creative exploration.
Kalantari: How does the brain differ when someone plays memorized music compared with improvising?
Barrett: Music is inherently multimodal: it engages auditory processing, motor planning, pattern recognition, visual imagery, emotion and proprioception. Limb’s 2008 study famously showed that when skilled jazz pianists improvised, activity in the dorsolateral prefrontal cortex decreased—essentially reducing self-monitoring—while activity in the medial prefrontal cortex increased, supporting personal artistic expression. In short, improvisation activates a distinct set of neural processes because it requires on-the-spot generative creativity rather than retrieval of memorized sequences.
Kalantari: You recently published research examining improvisation in children. Why study kids after working with trained adults?
Barrett: Much creativity research focuses on experts, who have deep repertoires and practiced patterns that guide improvisation. I wanted to understand the opposite end of the spectrum: how beginners, especially children with little or no musical training, approach generative music-making. Children’s brains are highly plastic and often approach tasks differently from adults, so they offer a window onto the innate roots of creative behavior.
To study them we prepared children carefully for fMRI scanning, teaching them to remain still and using a small keyboard connected to a laptop. I taught a simple scale and then encouraged them to play those notes in any order they liked. This allowed us to compare controlled scale playing with spontaneous improvisation in the scanner.
Kalantari: What did you find, and what does it tell us about creativity?
Barrett: The primary finding was that improvisation in children produced a pattern dominated by neural deactivation across sensory hubs—visible on brain maps as widespread blue regions—rather than the activation patterns commonly associated with adult artistic voice. These deactivations appear in areas that later form parts of adult creativity networks, suggesting that children’s improvisation may reflect early developmental stages of those systems. Crucially, we also observed that improvisation engaged subcortical reward circuits more than simple scale playing, implying that spontaneous creation is intrinsically rewarding for developing brains. This supports the idea that creative capacity is a built-in feature of brain function, not just an outcome of prolonged training.
Kalantari: What is your central takeaway from this work?
Barrett: The arts are inherently valuable and beneficial for brain health. Creativity and music activate unique and powerful brain systems that can be harnessed for well-being. A practical lesson is to quiet our inner critic and allow ourselves to be creative—whether through music, drawing, painting or crafts—without needing to be an expert. Engaging in creative activities is rewarding in itself and supports brain health across the lifespan. Recognizing that improvisation and creative thinking are fundamental to everyday life can make it easier for people to tap into their own creativity.
