Religion is a widespread feature of human life. Religions typically include both distinctive varieties experience and also set foundational beliefs. An additional, but often overlooked, part many religions their expression through specific actions, which we here designate religious motor behaviours. Here describe these behaviours offer taxonomy based on the conceptual schemes movement neuroscience neurology. Thus, rituals characterized by decreased output (e.g. ritualistic silence) increased ritual dances). Neurology distinguishes between movements that are experienced as voluntary or involuntary. We show this same distinction can apply to experiences, since may be either heightened sense personal control being controlled an external, divine source. then use structures investigate examples from wide range contexts. thereby categorize into different classes, focusing examples: repetitive actions; where volition altered, such automatisms; possession-like states. suggest scientific approach should predominant phenomenological presentation, accompanying subjective underlying neurocognitive mechanisms. This investigation shows rich parallels observed in neurological disorders, including those present with functional symptoms.

It is a central tenet of attachment theory that individual differences in representations organize behavior during social interactions. Secure also facilitate behavioral synchrony, key component adaptive parent-child Yet, the dynamic neural processes underlying these interactions and potential role remain largely unknown. A growing body research indicates interpersonal synchrony (INS) could be neurobiological correlate high interaction relationship quality. In this study, we examined whether are associated with parent child representations. total, 140 parents (74 mothers 66 fathers) their children (age 5-6 years; 60 girls 80 boys) engaged cooperative versus problem-solving. INS frontal temporal regions was assessed functional near-infrared spectroscopy hyperscanning.

Abstract Communication, especially conversation, is essential for human social life. Many previous studies have examined the neuroscientific underpinnings of i.e. language comprehension and speech production. However, conversation inherently involves two or more people, unless people actually interact with one another, nature cannot be truly revealed. Therefore, in this study, we used magnetoencephalographs that were connected together, simultaneously recorded brain activity while took turns speaking a word association/alphabet completion task. We compared amplitude modulation alpha- beta-band rhythms within each 62 regions under semantic (word association; less predictable) non-semantic (alphabet completion; conditions. found amplitudes significantly different between conditions wide range regions. Additionally, significant differences observed nearly same group after versus before utterance, indicating areas involved predicting partner’s next utterance. This result supports idea mentalizing, e.g. another person's speech, plays an important role suggests neural network implicated mentalizing extends over

Correlating transcriptional profiles with imaging-derived phenotypes has the potential to reveal possible molecular architectures associated cognitive functions, brain development and disorders. Competitive null models built by resampling genes self-contained spinning regions, along varying test statistics, have been used determine significance of associations. However, there no systematic evaluation their performance in imaging transcriptomics analyses. Here, we evaluated eight different statistics (mean, mean absolute value, squared max mean, median, Kolmogorov-Smirnov (KS), Weighted KS number significant correlations) both competitive models. Simulated maps (n=1,000) gene sets (n=500) were calculate probability (Psig) for each statistical test. Our results suggested that may result false positive driven co-expression within sets. Furthermore, demonstrated fail account distribution characteristics (e.g., bimodality) correlations between all available phenotypes, leading positives. These two confounding factors interacted differently resulting outcomes. Specifically, sign-sensitive (i.e., KS, KS) influenced bias models, while median sign-insensitive sensitive bimodality Additionally, KS-based produced conservative which increased risk negatives. Comprehensive supplementary analyses various configurations, including realistic scenarios, supported results. findings suggest utilizing such as statistic adopting confounder-matched coexpression-matched) an alternative standard can be a viable strategy.

Conduct disorder (CD) is among the most prevalent and burdensome disorders in early adolescence. Over past decade, there has been growing interest identifying reliable localized neurobiological markers of conduct (CD). However, recent meta-analyses have highlighted weak reliability these so-called markers, thereby limiting ability to draw firm conclusions. Using normative network mapping (598 healthy subjects), we rather sought investigate whether heterogeneous findings across studies may map unto a common brain network. A meta-analysis 38 fMRI involving adolescents with CD (932 cases, 975 controls) was first conducted showed only very spatial convergence activity alterations anterior temporal lobe (5 out studies). In turn, revealed that show consistent connectivity pattern whole brain, regional overlap reaching up 94.7% (36 This primarily driven by functional brainstem nuclei, subcortical structures (i.e., thalamus, ventral striatum), cingulate cortex posterior midcingulate), superior sulcus, visual cortices.

Social interactions induce interpersonal synchrony, occurs at different biobehavioral levels comprises behavioral, physiological, neurological activities. Hyperscanning—a neuroimaging technique that simultaneously measures the activity of multiple brain regions—has provided a powerful second-person neuroscience tool for investigating phase alignment neural during interactive behavior. Neural synchronization, revealed hyperscanning, is phenomenon called inter-brain synchrony- process purportedly facilitates prompting appropriate anticipation responses to each other's behaviors ongoing shared interactions.
