Increased interbrain synchronization and neural efficiency of the frontal cortex to enhance human coordinative behavior: A combined hyper-tES and fNIRS study

NeuroImage, Journal Year: 2023, Volume and Issue: 282, P. 120385 - 120385

Published: Oct. 12, 2023

Coordination is crucial for individuals to achieve common goals; however, the causal relationship between coordination behavior and neural activity has not yet been explored. Interbrain synchronization (IBS) efficiency in cortical areas associated with mirror neuron system (MNS) are considered two potential brain mechanisms. In present study, we attempted clarify how mechanisms facilitate using hypertranscranial electrical stimulation (hyper-tES). A total of 124 healthy young adults were randomly divided into three groups (the hyper-tACS, hyper-tDCS sham groups) underwent modulation right inferior frontal gyrus (IFG) during functional near-infrared spectroscopy (fNIRS). Increased IBS PFC or IFG (related MNS) was accompanied by greater behavior; had longer-lasting effects on behavior. Our findings highlight importance cortex suggest interventions improve different temporal windows.

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.

The study of the brain mechanisms underpinning social behavior is currently undergoing a paradigm shift, moving its focus from single individuals to real-time interaction among groups individuals. Although this development opens unprecedented opportunities how interpersonal activity shapes behaviors through learning, there have been few direct connections rich field learning science. Our article examines rapidly developing neuroscience (and could be) contributing our understanding learning. To end, we first review recent research extracting indices brain-to-brain coupling (BtBC) in context and, particular, We then discuss studying communicative during can aid interpretation BtBC and inform such behaviors. collectively predict outcomes, suggest several causative mechanistic models.

Three heads are better than one: cooperative learning brains wire together when a consensus is reached

Cerebral Cortex, Journal Year: 2022, Volume and Issue: 33(4), P. 1155 - 1169

Published: March 9, 2022

Abstract Theories of human learning converge on the view that individuals working together learn better than do those independently. Little is known, however, about neural mechanisms through cooperation. We addressed this research gap by leveraging functional near-infrared spectroscopy to record brain activity triad members in a group simultaneously. Triads were instructed analyze an ancient Chinese poem either cooperatively or Four main findings emerged. First, we observed significant within-group synchronization (GNS) left superior temporal cortex, supramarginal gyrus, and postcentral gyrus during cooperative compared with independent learning. Second, enhancement GNS triads was amplified when consensus reached (vs. elaboration argument) Third, predictive outcome at early stage (156–170 s after initiated). Fourth, social factors such as closeness (e.g. how much learners liked one other) reflected co-varied engagement. These results provide neuroscientific support for Piaget’s theory cognitive development favor notion successful cooperation involves dynamic consensus-building, which captured patterns shared across group.

Inter-brain synchronization occurs without physical co-presence during cooperative online gaming

Published: July 8, 2022

Inter-brain synchronization during social interaction has been linked with several positive phenomena, including closeness, cooperation, prosociality, and team performance. However, the temporal dynamics of inter-brain collaboration are not yet fully understood. Furthermore, increasingly happening online, dependence phase oscillatory activity on physical presence is an important but understudied question. In this study, physically isolated participants performed a collaborative coordination task in form cooperative multiplayer game. We measured EEG from 42 subjects working together as pairs task.

Analytical pipeline optimisation in developmental fNIRS hyperscanning data: Neural coherence between four- to six-year-olds collaborating with their mothers

Imaging Neuroscience, Journal Year: 2025, Volume and Issue: 3

Published: Jan. 1, 2025

Abstract Much of a child’s early learning takes place during social interactions with others. Neural synchrony, the temporal alignment individuals’ functional brain activity, is neural mechanism that may support successful interaction, but its biological origins and sensitivity to environmental factors remain unknown. This study measures coherence between 4- 6-year-old children their mothers using wearable near-infrared spectroscopy (“fNIRS”) in collaborative problem-solving hyperscanning paradigm. Best practices fNIRS data processing are incorporated optimise quantification extricate environmental- task-related effects. Results suggest physiological noise extracerebral layer artificially inflated strength both oxygenated (“HbO2”) deoxygenated (“HbR”) haemoglobin. Coherence remained stronger than individual problem solving chromophores after reduction. Phase-scrambled pseudodyad analyses supported interpretation collaboration relates dynamics interaction rather task- or environmental-related components.
