Changes in Brain Activation Associated with Spontaneous Improvization and Figural Creativity After...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Creativity Research

Background:

• Creativity is vital for entrepreneurship and daily adaptation.
• Neural underpinnings of creativity enhancement remain largely unexplored.
• Spontaneous improvization is a key facet of creative thinking.

Purpose of the Study:

• To investigate longitudinal neural changes associated with a Creative Capacity Building Program (CCBP).
• To compare brain activity changes between a CCBP and a Language Capacity Building Program (LCBP).
• To examine effects on spontaneous improvization skills.

Main Methods:

• Prospective, randomized control design over five weeks.
• fMRI task assessing spontaneous improvization (Pictionary-based).
• Pre- and post-intervention assessments of brain activity and skills.

Main Results:

• CCBP participants showed reduced activity in right dorsolateral prefrontal cortex, anterior/paracingulate gyrus, supplementary motor area, and parietal regions post-training.
• Increased cerebellar-cerebral connectivity was observed in CCBP participants compared to LCBP.
• Reduced engagement of executive functioning regions and increased implicit processing were noted.

Conclusions:

• Creative capacity enhancement via improvization training is linked to altered brain network engagement.
• Reduced reliance on executive control and increased spontaneous processing characterize enhanced creative capacity.
• Findings provide insights into the neural basis of creativity and its potential for enhancement.
