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.

A practical guide to EEG hyperscanning in joint action research: from motivation to implementation

Social Cognitive and Affective Neuroscience, Journal Year: 2024, Volume and Issue: 19(1)

Published: Jan. 1, 2024

Developments in cognitive neuroscience have led to the emergence of hyperscanning, simultaneous measurement brain activity from multiple people. Hyperscanning is useful for investigating social cognition, including joint action, because its ability capture neural processes that occur within and between people as they coordinate actions toward a shared goal. Here, we provide practical guide researchers considering using hyperscanning study action seeking avoid frequently raised concerns skeptics. We focus specifically on Electroencephalography (EEG) which widely available optimally suited capturing fine-grained temporal dynamics coordination. Our guidelines cover questions are likely arise when planning project, ranging whether appropriate answering one's research considerations design, dependent variable selection, data analysis visualization. By following clear facilitate careful consideration theoretical implications design choices other methodological decisions, can mitigate interpretability issues maximize benefits paradigms.

Gaze onsets during naturalistic infant-caregiver interaction associate with ‘sender’ but not ‘receiver’ neural responses, and do not lead to changes in inter-brain synchrony

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: March 2, 2023

Temporal coordination during infant-caregiver social interaction is thought to be crucial for supporting early language acquisition and cognitive development. Despite a growing prevalence of theories suggesting that increased inter-brain synchrony associates with many key aspects interactions such as mutual gaze, little known about how this arises Here, we investigated the role gaze onsets potential driver synchrony. We extracted dual EEG activity around naturally occurring in N = 55 dyads (mean age 12 months). differentiated between two types onset, depending on each partners' role. 'Sender' were defined at time when either adult or infant made shift towards their partner was already looking them (mutual) not (non-mutual). 'Receiver' Contrary our hypothesis found that, naturalistic interaction, both non-mutual associated changes sender, but receiver's brain increases above baseline. Further, mutual, compared inter Overall, results suggest effects are strongest intra-brain level, 'sender' 'receiver' gaze.

A growing body of research shows that the universal capacity for music perception and production emerges early in development. Possibly building on this predisposition, caregivers around world often communicate with infants using songs or speech entailing song-like characteristics.

Electroencephalograph (EEG) hyperscanning allows studying Interpersonal Neural Synchrony (INS) between two or more individuals across different social conditions, including parent-infant interactions. Signal pre-processing is crucial to optimize computation of INS estimates; however, few attempts have been made at comparing the impact dyadic EEG data methods on estimates. collected 31 mother-infant dyads (8-10 months) engaged in a Face-to-Face Still-Face Procedure were pre-processed with versions same pipeline, "automated" and "manual". Cross-frequency PLV theta (3-5Hz, 4-7Hz) alpha (6-9Hz, 8-12Hz) frequency bands computed after automated manual compared through Pearson's correlations Repeated Measures ANOVAs. PLVs theta, but not alpha, band significantly higher than pre-processing. Moreover, pipeline rejected lower percentage ICs epochs pipeline. While no direct comparison existing pipelines was made, this first study assessing methodological decisions, particularly degree automatization, cross-frequency dataset dyads. Non-directional phase-based indexes such as seem be affected by automatization Future research should strive for standardization methods.

Music tempo modulates emotional states as revealed through EEG insights

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 10, 2025

Music can effectively influence human emotions, with different melodies and rhythms eliciting varying emotional responses. Among these, tempo is one of the most important parameters affecting emotions. This study explores impact music on states associated brain functional networks. A total 26 participants without any history neurological or psychiatric disorders training took part in experiment, using classical piano clips at tempi (56, 106, 156 bpm) as stimuli. The was conducted scales electroencephalogram (EEG) analysis. results showed that valence level emotions significantly increased tempo, while arousal exhibited a "V" shape relationship. EEG analysis revealed significant changes brainwave signals across frequency bands under tempi. For instance, slow induced higher Theta Alpha power frontal region, fast Beta Gamma band power. Moreover, enhanced average connectivity strength frontal, temporal, occipital regions, phase synchrony value (PLV) between parietal regions. However, improves PLV findings this elucidate effects networks related to emotion regulation, providing theoretical basis for music-assisted diagnosis treatment mood disorders. Furthermore, these suggest potential applications robotics, emotion-based human-computer interaction, intelligent control.
