Neural correlates of creative writing: an fMRI study

Area of Science:

• Neuroscience
• Cognitive Psychology
• Creative Writing Studies

Background:

• The neural underpinnings of creative writing and their correlation with creative performance remain largely unexplored.
• Understanding the brain processes involved in spontaneous story generation is crucial for cognitive and literary research.

Purpose of the Study:

• To investigate cerebral activations during the creative writing process using functional magnetic resonance imaging (fMRI).
• To explore the neural correlates of creative performance in healthy participants.
• To differentiate brain activity between brainstorming, creative writing, reading, and copying tasks.

Main Methods:

• fMRI was employed on 28 healthy participants undertaking creative writing, brainstorming, reading, and copying tasks.
• Individual verbal creativity was assessed using a standardized verbal creativity test.
• Creative output quality was evaluated through qualitative ratings.

Main Results:

• Brainstorming activated a parieto-frontal-temporal network involved in cognitive, linguistic, and creative functions, alongside visual and imaginative processing.
• Creative writing engaged motor and visual areas for handwriting, plus cognitive and linguistic regions.
• Creative writing minus copying revealed right-lateralized activation in hippocampi, temporal poles (BA 38), and posterior cingulate cortex, associated with memory retrieval and semantic integration.
• Correlation analysis linked creative performance to activation in the left inferior frontal gyrus (BA 45) and left temporal pole (BA 38).

Conclusions:

• Creative writing involves a complex interplay of cognitive, linguistic, and motor brain functions.
• Verbal creativity during creative writing is associated with enhanced verbal and semantic memory retrieval and semantic integration.
• Specific brain regions, including the inferior frontal gyrus and temporal pole, are critical for creative verbal output.
