Emotional valence modulates the topology of the parent-infant inter-brain network

NeuroImage, Journal Year: 2019, Volume and Issue: 207, P. 116341 - 116341

Emotional communication between parents and children is crucial during early life, yet little known about its neural underpinnings. Here, we adopt a dual connectivity approach to assess how positive negative emotions modulate the interpersonal network infants their mothers naturalistic interaction. Fifteen were asked model toward pairs of objects social interaction with (mean age 10.3 months) whilst activity both was concurrently measured using electroencephalography (EEG). Intra-brain inter-brain in 6-9 Hz range (i.e. infant Alpha band) maternal expression computed directed (partial coherence, PDC) non-directed (phase-locking value, PLV) metrics. Graph theoretical measures used quantify differences topology as function emotional valence. We found that indices (Density, Strength Divisibility) consistently revealed strong effects valence on parent-child network. Parents showed stronger integration processes demonstrations than emotions. Further, metrics (PDC) indicated mother directional influences states. These results suggest parent-infant modulated by quality tone dyadic interactions, graph may be successfully applied examine these changes topology.

Dance on the Brain: Enhancing Intra- and Inter-Brain Synchrony

Frontiers in Human Neuroscience, Journal Year: 2021, Volume and Issue: 14

Dance has traditionally been viewed from a Eurocentric perspective as mode of self-expression that involves the human body moving through space, performed for purposes art, and by an audience. In this Hypothesis Theory article, we synthesize findings anthropology, sociology, psychology, dance pedagogy, neuroscience to propose The Synchronicity Dance, which states humans enhance both intra- inter-brain synchrony. We outline neurocentric definition dance, suggests neurobehavioral processes in seven distinct areas including sensory, motor, cognitive, social, emotional, rhythmic, creative. explore several avenues.

Proximity and touch are associated with neural but not physiological synchrony in naturalistic mother-infant interactions

NeuroImage, Journal Year: 2021, Volume and Issue: 244, P. 118599 - 118599

Caregiver touch plays a vital role in infants' growth and development, but its as communicative signal human parent-infant interactions is surprisingly poorly understood. Here, we assessed whether proximity caregiver-infant dyads are related to neural physiological synchrony. We simultaneously measured brain activity respiratory sinus arrhythmia of 4-6-month-old infants their mothers (N=69 dyads) distal proximal joint watching conditions well an interactive face-to-face condition.

Interpersonal Neural Synchrony During Father–Child Problem Solving: An fNIRS Hyperscanning Study

Child Development, Journal Year: 2021, Volume and Issue: 92(4)

Published: Jan. 10, 2021

Interpersonal neural synchrony (INS) has been previously evidenced in mother-child interactions, yet findings concerning father-child interaction are wanting. The current experiment examined whether fathers and their 5- to 6-year-old children (N = 66) synchronize brain activity during a naturalistic interaction, addressed paternal child factors related INS. Compared individual problem solving rest, dyads showed increased INS bilateral dorsolateral prefrontal cortex left temporo-parietal junction cooperative solving. Furthermore, the father's attitude toward his role as parent was positively cooperation condition. These results highlight implication of parenting processes for first time.

Multimodal hyperscanning reveals that synchrony of body and mind are distinct in mother-child dyads

NeuroImage, Journal Year: 2022, Volume and Issue: 251, P. 118982 - 118982

Published: Feb. 8, 2022

Hyperscanning studies have begun to unravel the brain mechanisms underlying social interaction, indicating a functional role for interpersonal neural synchronization (INS), yet that drive INS are poorly understood. The current study, thus, addresses whether is functionally-distinct from synchrony in other systems - specifically autonomic nervous system and motor behavior. To test this, we used concurrent near-infrared spectroscopy electrocardiography recordings, while N = 34 mother-child stranger-child dyads engaged cooperative competitive tasks. Only domain was higher compared observed. Further, were positively related during competition but not cooperation. These results suggest different behavioral biological may reflect distinct processes. Furthermore, they show increased unlikely be explained solely by shared arousal similarities, supporting recent theories postulate close relationships.

The use of functional near-infrared spectroscopy (fNIRS) hyperscanning during naturalistic interactions in parent–child dyads has substantially advanced our understanding the neurobiological underpinnings human social interaction. However, despite rise developmental studies over last years, analysis procedures have not yet been standardized and are often individually developed by each research team. This article offers a guide on fNIRS data MATLAB R. We provide an example dataset 20 assessed cooperative versus individual problem-solving task, with brain signal acquired using 16 channels located bilateral frontal temporo-parietal areas. toolboxes Homer2 SPM for to preprocess suggest procedure.

Quantification of inter-brain coupling: A review of current methods used in haemodynamic and electrophysiological hyperscanning studies

NeuroImage, Journal Year: 2023, Volume and Issue: 280, P. 120354 - 120354

Published: Sept. 4, 2023

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.
