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. Based on results literature survey, first report summary statistics field, followed brief overview each signal obtained from hyperscanning. We then discuss rationale, assumptions suitability method modalities Finally, issues surrounding interpretation method.

Mobile fNIRS for exploring inter-brain synchrony across generations and time

Frontiers in Neuroergonomics, Journal Year: 2024, Volume and Issue: 4

Published: Jan. 2, 2024

While still relatively rare, longitudinal hyperscanning studies are exceptionally valuable for documenting changes in inter-brain synchrony, which may turn underpin how behaviors develop and evolve social settings. The generalizability ecological validity of this experimental approach hinges on the selected imaging technique being mobile–a requirement met by functional near-infrared spectroscopy (fNIRS). fNIRS has most frequently been used to examine development synchrony behavior child-parent dyads. In position paper, we contend that dedicating attention intergenerational stands benefit fields cognitive neuroscience more broadly. We argue is particularly relevant understanding neural mechanisms underpinning dynamics, potentially benchmarking progress psychological interventions, many situated contexts. line with our position, highlight areas research stand be enhanced mobile devices, describe challenges arise from measuring across generations real world, offer potential solutions.

Interpersonal neural synchrony and mental disorders: unlocking potential pathways for clinical interventions

Frontiers in Neuroscience, Journal Year: 2024, Volume and Issue: 18

Published: March 11, 2024

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.

Attachment dimensions, guilt, shame, and self-esteem influence offline online interactions. In addition, these psychological variables are involved in the amount of time an individual uses Internet. Few studies have examined associations between self-esteem, attachment dimensions related to friendships romance contexts, how differ low high Internet Users (IU). The present study explored relationships assessed differences IU on variables. 213 participants completed self-report questionnaires. correlated positively with corresponding across contexts.

Getting closer to social interactions using electroencephalography in developmental cognitive neuroscience

Developmental Cognitive Neuroscience, Journal Year: 2024, Volume and Issue: 67, P. 101391 - 101391

Published: May 14, 2024

The field of developmental cognitive neuroscience is advancing rapidly, with large-scale, population-wide, longitudinal studies emerging as a key means unraveling the complexity developing brain and processes in children. While numerous neuroscientific techniques like functional magnetic resonance imaging (fMRI), near-infrared spectroscopy (fNIRS), magnetoencephalography (MEG), transcranial stimulation (TMS) have proved advantageous such investigations, this perspective proposes renewed focus on electroencephalography (EEG), leveraging underexplored possibilities EEG. In addition to its temporal precision, low costs, ease application, EEG distinguishes itself ability capture neural activity linked social interactions increasingly ecologically valid settings. Specifically, can be measured during lab, hyperscanning used study two (or more) people simultaneously, mobile measure real-life This paper summarizes research these three areas, making persuasive argument for inclusion into toolkit neuroscientists.
