Humans are highly social, typically without this ability requiring noticeable efforts. Yet, such social fluency poses challenges both for the human brain to compute and scientists study. Over last few decades, neuroscientific research of sociality has witnessed a shift in focus from single-brain analysis complex dynamics occurring across several brains, posing questions about what these mean how they relate multifaceted behavioural models. We propose term 'Relational Neuroscience' collate interdisciplinary field devoted modelling inter-brain subserving connections, spanning real-time joint experiences long-term bonds. Hyperscanning, i.e., simultaneously measuring activity multiple individuals, proven be promising technique investigate dynamics. Here, we discuss hyperscanning can help within Relational Neuroscience, considering variety subfields, including cooperative interactions dyads groups, empathy, attachment bonding, developmental neuroscience. While presenting Neuroscience light hyperscanning, our discussion also takes into account behaviour, physiology endocrinology properly interpret contexts. consider strengths but limitations caveats answer interacting people. The aim is provide an integrative framework future work build better theories contexts subfields model sociality.

The emergence of moral alignment within human groups is facilitated by interbrain synchrony

Communications Biology, Год журнала: 2025, Номер 8(1)

Abstract Humans tend to align their behaviors and beliefs with group peers. Establishing alignment between members is crucial for unity, yet the mechanisms underlying its emergence are under-explored. Here we examined extent which brains of synchronize during deliberation on moral issues, how interbrain synchrony supports in beliefs. We scanned 200 participants, who were divided into groups four, using functional Near-Infrared Spectroscopy (fNIRS) discussions dilemmas. Behavioral results show that following deliberations, aligned by adjusting private towards collective sentiment. Critically, neuroimaging reveal increased left inferior frontal gyrus (IFG) predicts degree post-deliberation. These findings indicate human tendency extends regions related mirroring semantic sequence processing work across coordination, promote shared

Analytical pipeline optimisation in developmental fNIRS hyperscanning data: Neural coherence between four- to six-year-olds collaborating with their mothers

Abstract Much of a child’s early learning takes place during social interactions with others. Neural synchrony, the temporal alignment individuals’ functional brain activity, is neural mechanism that may support successful interaction, but its biological origins and sensitivity to environmental factors remain unknown. This study measures coherence between 4- 6-year-old children their mothers using wearable near-infrared spectroscopy (“fNIRS”) in collaborative problem-solving hyperscanning paradigm. Best practices fNIRS data processing are incorporated optimise quantification extricate environmental- task-related effects. Results suggest physiological noise extracerebral layer artificially inflated strength both oxygenated (“HbO2”) deoxygenated (“HbR”) haemoglobin. Coherence remained stronger than individual problem solving chromophores after reduction. Phase-scrambled pseudodyad analyses supported interpretation collaboration relates dynamics interaction rather task- or environmental-related components.

Social interactions are a ubiquitous part of human life. They also complex and dynamic, posing challenge for traditional psychology methods. This article provides an overview dynamic systems approach to the study social that manages this complexity enables quantification interdependence between people. We discuss key empirical findings demonstrate how different forms interaction dynamics shape outcomes. Last, we highlight utility advancing theories behavior practical application. By adopting approach, researchers can gain deeper understanding patterns underlying test hypotheses about mechanisms driving connection coordination.

Inter-brain coupling during language learning contributes to learning outcomes

While knowledge and skill acquisition frequently occur in social interactions, the predominant focus of existing research remains centred on individual learning. Here, we investigate whether interaction enhances language learning, interbrain coupling changes across learning sessions. We utilized functional near-infrared spectroscopy to assess teacher-learner dyads engaging a two-session training set words their plural inflections novel language. compared group trained with mutual communication noninteractive group, which learner could see hear teacher, but teacher was unable or (one-way mirror). Results revealed that No-interaction Interaction exhibited faster reaction times for vocabulary recognition morphological first session.

Brain bases of real-time social interaction: A meta-analytic investigation of human neuroimaging studies

Introduction Social interactions play a central role in shaping brain function, but neuroscientific research on interactive social behavior has been limited by the restrictions of imaging environments. Although growing body neuroimaging situates participants real-time contexts, questions remain about systems critical for understanding interaction. This study addresses three primary questions: 1) Is there common network regions that underlies diverse forms interaction? 2) Are dissociable contribute to different aspects behavior? 3) What are networks and cognitive functions associated with socially brain? Methods We implemented systematic search human literature find studies involving interaction – were engaged interacted perceived partners contrasted against non-socially control conditions. used coordinate-based meta-analysis (CBMA) 108 elucidate regions. further analyzed subsets probe engagement (versus non-human) partner, non-interactive) reciprocal initiating (participant elicits response from partner) responding (to actions). Finally, we Brainmap Neurosynth databases conduct meta-analytic coactivation modeling (MACM) functional decoding better characterize neurocognitive Results The overarching CBMA uncovered significant convergence ten areas cut across large-scale networks. Follow-up analyses suggest reward system engagement, ventral attention interaction, partially relate behaviors. MACM results 3-4 overlapping underlie interaction: default mode (temporoparietal junction, medial prefrontal cortex, precuneus, cerebellum); lateral frontoparietal processes; intermediary midcingulo-insular emotion. Discussion current data-driven investigation advance our neural Our findings myriad may be subserved traverse multiple adds support emerging theories proposing centrality function.

Hyper-brain hyper-frequency network topology dynamics when playing guitar in quartet

Ensemble music performance is a highly coordinated form of social behavior requiring not only precise motor actions but also synchronization different neural processes both within and between the brains ensemble players. In previous analyses, which were restricted to within-frequency coupling (WFC), we showed that frequencies participate in intra- inter-brain coordination, exhibiting distinct network topology dynamics underlie interactions. However, many couplings are likely operate across frequencies. Hence, obtain more complete picture hyper-brain interaction when musicians play guitar quartet, cross-frequency (CFC) has be considered as well. Furthermore, WFC CFC can used construct hyper-frequency networks (HB-HFNs) integrating all information flows oscillation frequencies, providing important details about terms (NTD). Here, reanalyzed EEG (electroencephalogram) data obtained from four guitarists playing together quartet explore changes HB-HFN their relation acoustic signals music. Our findings demonstrate low-frequency oscillations (e.g., delta, theta, alpha) an integrative or pacemaker role such complex HFN specifically related assessed by sound properties. Simulations link removal relatively robust against loss connections, especially strongest connections preserved affects brain one guitarist. We conclude HB-HFNs capture mechanisms support interpersonally action behavioral synchrony.
