【 摘 要 】

The neuroscience of creativity seeks to disentangle the complex brain processes that underpin the generation of novel ideas. Neuroimaging studies of functional connectivity, particularly functional magnetic resonance imaging (fMRI), have revealed individual differences in brain network organization associated with creative ability; however, much of the extant research is limited to laboratory-based divergent thinking measures. To overcome these limitations, we compare functional brain connectivity in a cohort of creative experts (n = 27) and controls (n = 26) and examine links with creative behavior. First, we replicate prior findings showing reduced connectivity in visual cortex related to higher creative performance. Second, we examine whether this result is driven by integrated or segregated connectivity. Third, we examine associations between functional connectivity and vivid distal simulation separately in creative experts and controls. In accordance with past work, our results show reduced connectivity to the primary visual cortex in creative experts at rest. Additionally, we observe a negative association between distal simulation vividness and connectivity to the lateral visual cortex in creative experts. Taken together, these results highlight connectivity profiles of highly creative people and suggest that creative thinking may be related to, though not fully redundant with, the ability to vividly imagine the future. Author Summary This study sought to uncover the neurocognitive basis of creativity by comparing brain connectivity in a cohort of creative experts and controls. Using graph theory methods, we replicate past work showing reduced connectivity to the primary visual cortex in highly creative people. Additionally, we observed a negative association between vividness of distal future simulation and connectivity to the lateral visual cortex in creative experts. Taken together, these findings highlight connectivity profiles of highly creative people and suggest that creative thinking may be related to the ability to vividly imagine events in the distant future.
