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.

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

Social Cognitive and Affective Neuroscience, Год журнала: 2024, Номер 19(1)

Опубликована: Янв. 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, Год журнала: 2023, Номер 13(1)

Опубликована: Март 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.

Exploring the impact of manual and automatic EEG pre-processing methods on interpersonal neural synchrony measures in parent-infant hyperscanning studies

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.

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. This suggests might be one earliest developing most accessible forms interpersonal communication, providing a platform studying communicative behavior. However, little has examined truly contexts. The current work aims to facilitate development experimental approaches rely dynamic naturalistic social interactions. We first review two longstanding lines examine musical interactions by focusing either caregiver infant. These include defining acoustic non-acoustic features characterize infant-directed (ID) music, as well behavioral neurophysiological examining infants' processing timing pitch. Next, we recent studies looking at holistically. focuses how interact achieve co-regulation, mutual engagement, increase affiliation prosocial conclude discussing methodological, technological, analytical advances empower comprehensive study communication childhood.

Parent–infant EEG is a novel hyperscanning paradigm to measure social interaction simultaneously in the brains of parents and infants. The number studies using parent–infant dual-EEG as theoretical framework brain-to-brain synchrony during rapidly growing, while methodology for measuring not yet uniform. While adult quickly improving, open databases, tutorials, methodological validations with infants are largely missing. In this practical guide, we provide step-by-step manual on how implement run paradigms neurodevelopmental laboratory naturalistic settings (e.g., free interactions). Next, highlight insights variety choices that can be made (pre)processing data, including recommendations interpersonal neural coupling metrics interpretations results. Moreover, an exemplar dataset two mother–infant dyads interactions (“free play”) may serve practice material.

Music tempo modulates emotional states as revealed through EEG insights

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 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.
