Brain's Creative Bridge Uncovered in Rostral Prefrontal Cortex
A new study links creativity to a functional gradient in the rostral prefrontal cortex that bridges the default mode network (DMN) and the executive control network (ECN). The greater the separation (gradient amplitude) between DMN and ECN, the higher a person’s creative ability; in behavioral variant frontotemporal dementia this gradient compresses, reducing everyday problem-solving creativity yet sometimes sparking artistic activity due to loss of control. The rostral PFC thus acts as a tunable bridge enabling both spontaneous idea generation and deliberate idea refinement.
