Abstract It is a central tenet of attachment theory that individual differences in representations organize behavior during social interactions. Secure also facilitate behavioral synchrony, key component adaptive parent–child Yet, the dynamic neural processes underlying these interactions and potential role remain largely unknown.

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.

Unraveling emotional regulation through multimodal neuroimaging techniques

Brainbridge, Journal Year: 2024, Volume and Issue: 1(1), P. 1 - 26

Published: May 30, 2024

Neuroimaging techniques have significantly advanced our understanding of emotional regulation by elucidating the neural mechanisms involved. This review synthesizes findings across multiple modalities—functional Magnetic Resonance Imaging (fMRI), Electroencephalography (EEG), Magnetoencephalography (MEG), Positron Emission Tomography (PET), and Spectroscopy (MRS)—to highlight key insights into processing. The prefrontal cortex (PFC), amygdala, hippocampus, insula emerge as critical brain regions in regulating emotions. fMRI studies demonstrate increased PFC activity decreased amygdala responses during effective emotion regulation, indicating top-down control mechanisms. EEG MEG provide temporal dynamics responses, capturing rapid changes tasks. PET MRS reveal neurochemical basis emphasizing roles neurotransmitters like serotonin dopamine. Integration multimodal approaches, such fMRI-EEG fMRI-PET, enhances combining spatial, temporal, specificity. Challenges include methodological limitations need for diverse participant samples to improve generalizability. Future research should focus on improving spatial resolution, adopting longitudinal ecologically valid designs, fostering interdisciplinary collaborations. These advancements hold promise developing personalized interventions treatments disorders leveraging neuroimaging biomarkers underpinnings regulation.

Abstract Humans tend to align their behaviors and beliefs with group peers. Establishing alignment between members is crucial for unity, yet the mechanisms underlying its emergence are under-explored. Here we examined extent which brains of synchronize during deliberation on moral issues, how interbrain synchrony supports in beliefs. We scanned 200 participants, who were divided into groups four, using functional Near-Infrared Spectroscopy (fNIRS) discussions dilemmas. Behavioral results show that following deliberations, aligned by adjusting private towards collective sentiment. Critically, neuroimaging reveal increased left inferior frontal gyrus (IFG) predicts degree post-deliberation.

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.
