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.

Abstract Our daily interactions with the world are shaped by sensory expectations informed context and prior experiences, which in turn influence how we allocate our attention. Prominent predictive coding models suggest that expectancy attention interact but disagree on precise mechanisms. One possibility is Ventral Attention Network (VAN), may play a role facilitating attentional reorienting when violated. To test this, employed an auditory-visual trial-by-trial cueing paradigm three experiments integrating EEG fMRI to investigate VAN’s violations of cross-modal expectancy. Behavioral results showed faster responses expected targets, confirming efficacy cue-induced orienting target modality. analyses revealed differences early (∼100 ms latency) event-related potentials (ERPs) both auditory visual stimuli were Unexpected elicited significantly larger early-latency negative ERPs, across modalities.

Functional connectivity further greater coupling between VAN regions cortices, modality-specific pathways involving superior temporal gyrus (STG) for fusiform (FG) targets. These findings demonstrate recruit reorient resolve conflict. By coordinating top-down control bottom-up input, supports adaptive unexpected stimuli.

Background: The Autism Spectrum Disorder (ASD) characteristic of difficulties in social communication and interaction has been previously associated with elevated anxiety the degree mental effort required to understand respond cues. These associations have implications for health autistic youth, but they are usually based on correlational statistics between measures demands that collected formal psychological testing settings. Another index found correlate anxious arousal is gamma wave activity, which measured via EEG. Methods: To compare data from both these indicators anxiety, a two-stage study was conducted using (1) standardized test (2) vivo EEG low-demand setting. Results: As well as significant cognition scales, there were also meaningful relationships activity. Conclusions: Because activity represents highest level cognitive complexity brain an hypervigilance under threatening conditions, findings suggest even low-level demand settings may initiate high-level anxiety-related behaviour youth.

Background/Objectives: Advancements in biomedical imaging technologies over the past few decades have made it increasingly possible to measure long-term effects of exercise on central nervous system. This study aims compare brain morphology and functional connectivity wrestlers handball players, exploring sport-specific neural adaptations. Methods: Here, we examined 26 elite male athletes (13 13 players) using anatomical resting-state magnetic resonance (fMRI) measurements. Connectivity maps are derived seed-based correlation analysis fMRI, while voxel-based morphometry (VBM) is employed identify differences. Additionally, cortical thickness global volumetric values segmented images determine distinctions between players non-parametric statistical tests. Results: Wrestlers exhibited greater grey matter volume (GMV) right middle temporal gyrus, left frontal posterior cingulate gyrus (uncorr., p < 0.001). On other hand, showed increased superior parahippocampal anterior orbital gyrus–medial region (P(FWE) 0.05). In addition, several regions. Conclusions: The GMV, thickness, observed highlight presence While this research provides valuable insights into neuroplastic various athletic disciplines, further studies involving additional sports control groups needed for a more comprehensive understanding.

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.

Abstract Humor has been considered an effective emotion regulation strategy, and some behavioral studies have examined its superior effects on negative regulation. However, neural mechanisms remain unknown. Our functional magnetic resonance imaging study directly compared the bases of humorous coping (reappraisal) ordinary reappraisal following exposure to pictures. The results suggested that was more in downregulating emotions upregulating positive both short long term. We also found 2 cooperative pathways involved with stimuli by means humor: “hippocampal–thalamic–frontal pathway” “amygdala–cerebellar pathway.” former is associated restructuring mental representations situations accompanied insightful (“Aha!”) experience, while latter emotional release expression laughter (“Haha!”). Furthermore, degree hippocampal connectivity thalamus frontal cortex positively correlated changes emotion, this result implied could be strongly related depth cognitive reconstruction. These findings highlight regulating humor involves emotions.
