Brain activity and connectivity during poetry composition: Toward a multidimensional model of the creative process

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychology

Background:

• Creativity is a complex trait studied through creative process phases, product quality, and expertise.
• Previous neuroimaging studies have examined these aspects in isolation.
• A comprehensive understanding requires simultaneous examination of interacting creative features.

Purpose of the Study:

• To investigate creativity by simultaneously assessing process, product, and expertise during poetry composition.
• To identify distinct neural activation and connectivity patterns associated with different creative phases and expertise levels.

Main Methods:

• Neuroimaging (fMRI) was used to examine brain activity during poetry generation and revision.
• Participants included experts and novices in poetry composition.
• Poetry quality was assessed by an independent panel, and connectivity patterns were analyzed.

Main Results:

• Distinct activation patterns were observed for generation (attenuated cognitive control) and revision (re-engaged cognitive control) phases.
• Experts exhibited stronger deactivation in dorsolateral prefrontal and parietal executive systems (DLPFC/IPS) during generation.
• Poetry quality correlated with divergent connectivity patterns in experts and novices, centered on MPFC and DLPFC/IPS.

Conclusions:

• A unified neurocognitive model of creativity involves dynamic interactions between medial prefrontal cortex (motivation) and DLPFC/IPS (cognitive control).
• Experts may leverage enhanced cognitive control suspension for superior creative output.
• Shared cognitive resources are available to both experts and novices, with expertise influencing connectivity and quality.
