This study investigated whether transcranial direct current stimulation (tDCS) targeting the inferior frontal gyrus (IFG) can alter thinking process and neural basis of creativity. Participants' performance on compound remote associates (CRA) task was analyzed considering semantic features each trial after receiving different tDCS protocols (left cathodal right anodal, L + R−; left L−R+; Sham). Moreover, we constructed compared 80 prediction models CRA for group based task-related functional connectivity. Results showed that R− improved in semantically bundled trials, while L−R+ enhanced trials with greater distance. Furthermore, alpha-band connectivity lateralization than other two groups. These findings suggest bilateral IFG alters cognitive processes during creative ideation rather enhancing or impairing an established process.

Creativity is hypothesized to arise from a mental state which balances spontaneous thought and cognitive control, corresponding functional connectivity between the brain's Default Mode (DMN) Executive Control (ECN) Networks. Here, we conduct large-scale, multi-center examination of this hypothesis. Employing meta-analytic network neuroscience approach, analyze resting-state fMRI creative task performance across 10 independent samples Austria, Canada, China, Japan, United States (N = 2433)—constituting largest most ethnically diverse creativity study date. Using time-resolved analysis, investigate relationship (i.e., divergent thinking ability) dynamic switching DMN ECN. We find that creativity, but not general intelligence, can be reliably predicted by number DMN-ECN switches. Importantly, identify an inverted-U degree balance switching, suggesting optimal requires balanced brain dynamics. Furthermore, task-fMRI validation 31) demonstrates higher during idea generation (compared control condition) replicates relationship. Therefore, provide robust evidence datasets tied capacity dynamically switch networks supporting controlled cognition. Robust

Abstract Creativity neuroscience has consistently reported increased functional connectivity between the default mode network and executive control supports creative cognition, potentially reflecting coordination of generative evaluative cognitive processes. However, evidence been purely correlational—no causal demonstrations show that network–executive interaction specifically drives performance. We sought for coupling in thinking using near-infrared spectroscopy–brain neurofeedback, which can endogenously modify through reinforcement learning. Importantly, we employed covert where participants were unaware specific brain activity being trained, allowing unbiased evaluation neural impacts. In a default-executive neurofeedback condition (n = 15), entrained medial prefrontal cortex dorsolateral cortex, hubs network, respectively. compared this with default-motor entraining supplementary motor area. Approximately 24 h later, led to during task (generating object uses), extending broader regions. Behaviorally, observed double dissociation: The default–executive idea originality, while improved go/no-go reaction times. thus provide first causally enhances

On the basis of confluence theories creativity, creative ideation depends on forging links between existing memory traces. The synergy and thought is well-established, but neural dynamics integration for creativity are understudied. Here, we extended traditional paradigm. Participants read, recalled narratives, wrote endings. Computational linguistic analysis showed that those integrating more noncentral events—those less semantically connected to other events within narrative—wrote original Analyzing fMRI data captured during narrative encoding, discovered story ending originality can be predicted by shared event representation across participants in right Brodmann area 25 (BA25) stronger hippocampal segmentation signal encoding. These results held different types (i.e., crime, romance, fantasy stories). Overall, these offer notable insights, from perspective network structure into how humans encode retrieve complex real-world experiences enhance creativity.
