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.

Humans synchronize with one another to foster successful interactions. Here, we use a multimodal data fusion approach the aim of elucidating neurobiological mechanisms by which interpersonal neural synchronization (INS) occurs. Our meta-analysis 22 functional magnetic resonance imaging and 69 near-infrared spectroscopy hyperscanning experiments (740 3721 subjects) revealed robust brain regional correlates INS in right temporoparietal junction left ventral prefrontal cortex.

Visualizing the invisible tie: Linking parent–child neural synchrony to parents’ and children's attachment representations

Interpersonal motor synchrony in autism: a systematic review and meta-analysis

Frontiers in Psychiatry, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 19, 2024

Introduction Interpersonal motor synchrony (IMS) is the spontaneous, voluntary, or instructed coordination of movements between interacting partners. Throughout life cycle, it shapes social exchanges and interplays with intra- inter-individual characteristics that may diverge in Autism Spectrum Disorder (ASD). Here we perform a systematic review meta-analysis to summarize extant literature quantify evidence about reduced IMS dyads including at least one participant diagnosis ASD. Methods Empirical from sixteen experimental studies was systematically reviewed, encompassing spontaneous paradigms as well paucity measures used assess IMS. Of these, thirteen (n = 512 dyads) contributed an situ neurotypical partner (TD) for ASD control groups, which could be meta-analyses. Results Reduced synchronization ASD-TD emerged both meta-analyses, although small large effect sizes (i.e., Hedge’s g) favor group are consistent data (Hedge’s g .85, p < 0.001, 95% CI[.35, 1.35], PI[-.89, 2.60]). Discussion Uncertainty discussed relative type task, measures, age range considered each study. We further discuss sharing similar experiences world might help synchronize another. Future should not only whether consistently observed how this exchanges, but also explore ASD-ASD during interpersonal exchanges.
