Human creative thinking is unique and capable of generating novel valuable ideas. Recent research has clarified the contribution different brain networks (default mode network, DN; executive control network; salience network) to thinking. However, effects stimulation on during performance have not been clarified. The present study was designed examine changes in functional connectivity (FC) effective (EC) large-scale ensuing performance, induced by transcranial direct current (tDCS). Fourteen healthy male students underwent two tDCS sessions, one with actual sham stimulation, separate days. Participants (anode over left dorsolateral prefrontal cortex, DLPFC; cathode right inferior parietal lobule, IPL) for 20 min. Before after session, electroencephalography signals were acquired from 32 electrodes whole head task. On FC analysis, delta band between posterior cingulate cortex IPL significantly increased only real stimulation. We also found that change flexibility score correlated in: (i) mPFC lateral temporal (LTC) (ii) alpha LTC. EC decreased flow within DN (from LTC observed. Our results reveal could affect networks, particularly DN, modulate key generation flexible

Abstract Novelty and appropriateness are two fundamental components of creativity. However, the way in which novelty separated at behavioral neural levels remains poorly understood. In present study, we aim to distinguish bases creative idea generation. alignment with established theories thinking, respectively, emphasize semantic association executive control, results indicate that relies more on associative abilities, while functions. Next, employing a connectome predictive modeling (CPM) approach resting-state fMRI data, define functional network-based models—dominated by interactions within default network limbic network—that predict (i.e., cross-brain prediction). Furthermore, generalizability specificity connectivity patterns verified additional task fMRI. Finally, patterns, respectively mediate relationship between association/executive control novelty/appropriateness. These findings provide global distinctions

Abstract The cerebellum plays a crucial role in functions, including sensory‐motor coordination, cognition, and emotional processing. Compared to the neocortex, human exhibits protracted developmental trajectory. This delayed timeline may lead increased sensitivity of external influences, potentially extending vulnerability period for neurological disorders. Abnormal cerebellar development individuals with autism has been confirmed, these atypical changes affect neocortex. However, due heterogeneity spectrum disorder (ASD), regional cerebellocerebral structural relationship remain unknown. To address issues, we utilized imaging methods optimized cerebrum on 817 aged 5–18 years ABIDE II dataset. After FDR correction, significant differences between groups were found right crus II/VIIB vermis VI‐VII. Structural covariance analysis revealed enhanced parahippocampal gyrus, pars opercularis, transverse temporal gyrus hemisphere after correction. Furthermore, some regions varied across sexes. A increase specific subcortical structures was also observed ASD. Our study patterns autism, which suggested that underlying pathological processes ASD might concurrently brain regions. provided insight into potential pathways as therapeutic targets

What drives us to search for creative ideas, and why does it feel good find one? While previous studies demonstrated the positive influence of motivation on abilities, how reward subjective values play a role in creativity remains unknown.

On the dark side of creativity, creative ideation is intentionally used to damage others. This first electroencephalogram (EEG) study on malevolent creativity investigated task-related power (TRP) changes in alpha band while n = 89 participants (52 women, 37 men) generated original ideas for revenge psychometric Malevolent Creativity Test. TRP were assessed different stages idea generation process and linked performance indicators creativity. revealed three crucial findings: 1) yielded topographically distinct increases similar conventional ideation. 2) Time-related activity during reflected early prefrontal mid-stage temporal individuals with higher performance. performance-related, time-sensitive pattern may reflect conceptual expansion from prosocial antisocial perspectives, subsequent inhibition dominant semantic associations favor novel ideas. 3) The observed, right-lateralized over entire phase denote an additional emotional load Our highlights seminal role EEG oscillations as a biomarker also when processes operate context.

Storytelling has been pivotal for the transmission of knowledge and cultural norms across human history. A crucial process underlying generation narratives is exertion cognitive control on semantic representations stored in memory, a phenomenon referred as control. Despite extensive literature investigating neural mechanisms generative language tasks, little effort done towards storytelling under naturalistic conditions. Here, we probed participants to generate stories response set instructions which triggered narrative that was either appropriate (ordinary), novel (random), or balanced (creative), while recording functional magnetic resonance imaging (fMRI) signal. By leveraging deep models, demonstrated how ideally level during story generation. At level, creative were differentiated by multivariate pattern activity frontal cortices compared ordinary ones fronto- temporo-parietal with respect randomly generated stories. Crucially, similar brain regions also encoding features distinguished behaviourally. Moreover, decomposed dynamics into connectome harmonic modes found specific spatial frequency patterns modulation Finally, different coupling within between default mode, salience networks when contrasting their controls. Together, our findings highlight regulation exploration ideation contribute deeper understanding underpinning role storytelling.
