The transition to technologically-assisted communication has permeated all facets of human social life; yet, its impact on the brain is still unknown and effects may be particularly intense during periods developmental transitions. Applying a two-brain perspective, current preregistered study utilized hyperscanning EEG measure brain-to-brain synchrony in 62 mother-child pairs at adolescence (child age; M = 12.26, range 10-14) live face-to-face interaction versus remote communication. elicited 9 significant cross-brain links between densely inter-connected frontal temporal areas beta [14-30 Hz]. Mother's right region connected with child's left frontal, temporal, central regions, suggesting regulatory role organizing dynamics. In contrast, only 1 cross-brain-cross-hemisphere link, attenuating robust right-to-right-brain connectivity moments that communicates socio-affective signals. Furthermore, while level behavior was comparable two interactions, brain-behavior associations emerged exchange.

Our findings indicate co-presence underpinned by specific neurobiological processes should studied depth.

Mother–Infant Brain-to-Brain Synchrony Patterns Reflect Caregiving Profiles

Biobehavioral synchrony, the coordination of physiological and behavioral signals between mother infant during social contact, tunes child's brain to world. Probing this mechanism from a two-brain perspective, we examine associations patterns mother-infant inter-brain synchrony two well-studied maternal orientations-sensitivity intrusiveness-which have repeatedly been shown predict positive negative socio-emotional outcomes, respectively. Using dual-electroencephalogram (EEG) recordings, measure connectivity 60 mothers their 5- 12-month-old infants face-to-face interaction. Thirty connections show significantly higher correlations real interaction compared surrogate data. Brain-behavior indicate that sensitivity linked with greater neural whereas intrusiveness is associated lower coordination. Post hoc analysis reveals mother-right-frontal-infant-left-temporal connection particularly sensitive mother's style, while mother-left-frontal-infant-right-temporal indexes intrusive style. Our results support perspective by which mature brains externally regulate immature living suggest one pathway exert long-term effect may relate provision coordinated inputs its period maturation.

Generation WhatsApp: inter-brain synchrony during face-to-face and texting communication

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Feb. 1, 2024

Abstract Texting has become one of the most prevalent ways to interact socially, particularly among youth; however, effects text messaging on social brain functioning are unknown. Guided by biobehavioral synchrony frame, this pre-registered study utilized hyperscanning EEG evaluate interbrain during face-to-face versus texting interactions. Participants included 65 mother-adolescent dyads observed conversation compared from different rooms. Results indicate that both and communication elicit significant neural surrogate data, demonstrating for first time brain-to-brain texting. Direct comparison between two interactions highlighted 8 fronto-temporal links were significantly stronger in interaction Our findings suggest partners co-create a network inter-brain connections live exchanges. The degree improvement partners' right-frontal-right-frontal connectivity correlated with greater behavioral synchrony, suggesting well-researched connection may be specific communication. while technology-based allows humans synchronize afar, remain superior mode interpersonal connection. We conclude discussing potential benefits drawbacks pervasive use texting, youth.

Infants’ brain responses to social interaction predict future language growth

Current Biology, Journal Year: 2024, Volume and Issue: 34(8), P. 1731 - 1738.e3

Published: April 1, 2024

In face-to-face interactions with infants, human adults exhibit a species-specific communicative signal. Adults present distinctive "social ensemble": they use infant-directed speech (parentese), respond contingently to infants' actions and vocalizations, react positively through mutual eye-gaze smiling. Studies suggest that this social ensemble is essential for initial language learning. Our hypothesis the attracts attentional systems sensorimotor prepare infants vocally, both of which advance Using infant magnetoencephalography (MEG), we measure 5-month-old neural responses during live verbal (F2F) interaction an adult (social condition) control (nonsocial in turns away from speak another person. longitudinal design, tested whether brain these conditions at 5 months age predicted their growth five future time points.

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.

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.

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.
