Hyperscanning is a form of neuroimaging experiment where the brains two or more participants are imaged simultaneously whilst they interact. Within domain social neuroscience, hyperscanning increasingly used to measure inter-brain coupling (IBC) and explore how brain responses change in tandem during interaction. In addition cognitive research, some have suggested that quantification interplay between interacting can be as biomarker for variety mechanisms aswell investigate mental health developmental conditions including schizophrenia, anxiety autism. However, many different methods been quantify this lead questions about comparability across studies reduce research reproducibility. Here, we review quantifying IBC, suggest ways moving forward. Following PRISMA guidelines, reviewed 215 studies, four imaging modalities: functional near-infrared spectroscopy (fNIRS), magnetic resonance (fMRI), electroencephalography (EEG) magnetoencephalography (MEG). Overall, identified total 27 compute IBC. The most common modality fNIRS, by 119 89 which adopted wavelet coherence.

Whether and how shared intentionality (SI) influences the establishment of a novel interpersonal communication system is poorly understood. To investigate this issue, we designed coordinating symbolic game (CSCG) applied behavioral, functional near-infrared spectroscopy (fNIRS)-based hyperscanning, hyper-transcranial alternating current stimulation (hyper-tACS) methods. Here show that SI strong contributor to communicative accuracy. Moreover, SI, accuracy, neural synchronization (INS) in right superior temporal gyrus (rSTG) are higher when dyads successfully establish system. Furthermore, accuracy by increasing INS. Additionally, using time series long short-term memory network analyses, find INS can predict at early formation stage Importantly, partially mediates relationship between only In contrast, established, no longer contribute Finally, hyper-tACS experiment confirms has causal effect on These findings suggest behavioral mechanism, subserved INS, underlies

Introduction Interpersonal synchronization involves the alignment of behavioral, affective, physiological, and brain states during social interactions. It facilitates empathy, emotion regulation, prosocial commitment. Mental disorders characterized by interaction dysfunction, such as Autism Spectrum Disorder (ASD), Reactive Attachment (RAD), Social Anxiety (SAD), often exhibit atypical with others across multiple levels. With introduction “second-person” neuroscience perspective, our understanding interpersonal neural (INS) has improved, however, so far, it hardly impacted development novel therapeutic interventions. Methods To evaluate potential INS-based treatments for mental disorders, we performed two systematic literature searches identifying studies that directly target INS through neurofeedback (12 publications; 9 independent studies) or stimulation techniques (7 studies), following PRISMA guidelines. In addition, narratively review indirect manipulations biofeedback, hormonal We discuss ASD, RAD, SAD using a database search assess acceptability (4 neurostimulation in patients dysfunction. Results Although behavioral approaches, engaging eye contact cooperative actions, have been shown to be associated increased INS, little is known about long-term consequences Few proof-of-concept utilized techniques, like transcranial direct current neurofeedback, showing feasibility preliminary evidence interventions can boost synchrony connectedness. Yet, optimal protocols parameters are still undefined. For SAD, far no randomized controlled trial proven efficacy intervention although general methods seem well accepted these patient groups.

What interpersonal neural pathway in real-world settings determining successful information propagation naturalistic two-person persuasion scenarios? Hereby, we extended prior research on a dyadic paradigm (NDP) using dual-fNIRS protocol simultaneously measured the activity from persuader-receiver dyads while they engaged modified “Arctic Survival Task.” Investigating whether coupling between persuaders receivers underpinning of persuading predict outcomes (i.e., receiver’s compliance). Broadly, indicated that persuasive arguments increase significantly compared non-persuasive left superior temporal gyrus-superior frontal gyrus gyrus-inferior gyrus. G-causality indices further revealed directionality flows persuader receiver. Critically, could better predictor relative traditional self-report measures. Eventually, dynamics incorporating video recording marked micro-level processes response messages possibly reflecting time might occurs. The initial case with targeted views is valuable as first step encouraging compliance.

Intergroup relationships have been posited to influence individuals’ interpersonal interactions significantly. Using electroencephalography hyperscanning, this study aimed establish whether intergroup cooperation underlying neural mechanisms. According results, in-group Coop-index is better than out-group, whereas out-group Comp-index stronger in-group. The functional connectivity between frontal-central region right temporoparietal junction β band was cooperation. left α competition. In both competition, exhibited higher interbrain synchronization prefrontal cortex parietal θ band, as well compared out-group. intrabrain phase-locking value bands can effectively predict performance tasks. Interbrain be predicted a task. This offers neuroscientific evidence for favoritism bias at an level.
