Abstract Social interaction is of fundamental importance to humans. Prior research has highlighted the link between interbrain synchrony and positive outcomes in human social interaction. Neurofeedback an established method train one’s brain activity might offer a possibility increase synchrony. Consequently, it would be advantageous determine feasibility creating neurofeedback system for enhancing benefit In this study, we investigated whether most widely employed metric synchrony, namely wavelet transform coherence, can assessed accurately near real-time using functional near-infrared spectroscopy (fNIRS), which recognized its mobility ecological suitability interactive research. To end, have undertaken comprehensive approach encompassing simulations re-evaluation two human-interaction datasets. Our findings indicate potential stable measurement coherence integration durations about one minute. This align well with methodology intermittent procedure. investigation lays technical foundation fNIRS-based measure real-time. advancement crucial future development training tailored enhance potentially

A dual-brain therapeutic approach using noninvasive brain stimulation based on two-person neuroscience: A perspective review

Mathematical Biosciences & Engineering, Год журнала: 2024, Номер 21(4), С. 5118 - 5137

<abstract> <p>Our actions and decisions in everyday life are heavily influenced by social interactions, which dynamic feedback loops involving actions, reactions, internal cognitive processes between individual agents. Social interactions induce interpersonal synchrony, occurs at different biobehavioral levels comprises behavioral, physiological, neurological activities. Hyperscanning—a neuroimaging technique that simultaneously measures the activity of multiple brain regions—has provided a powerful second-person neuroscience tool for investigating phase alignment neural during interactive behavior. Neural synchronization, revealed hyperscanning, is phenomenon called inter-brain synchrony- process purportedly facilitates prompting appropriate anticipation responses to each other's behaviors ongoing shared interactions. In this review, I explored therapeutic dual-brain approach using noninvasive stimulation target synchrony based on modulate interaction. Artificially inducing brains potential adjunct physiotherapy, psychotherapy, pain treatment- strongly interaction therapist patient. Dual-brain approaches personalize parameters must consider temporal, spatial, oscillatory factors. Multiple data fusion analysis, assessment plasticity, closed-loop system, brain-to-brain interface can support personalized stimulation.</p> </abstract>

Purpose: : The objective is to suggest time as an important variable consider in the network model, specifically when discussing causality. Methods: There a consideration of context functional connectivity because importance observing feature inside neuroscience context. Using set comprised three rats Local Field Potentials, model was constructed from data using Bayesian Network method, considering and not taking into account delay communication among brain areas recorded this study. To end, there appliance Delayed Mutual Information method identify lag between Potentials K2 Score compare models. Results: depicted probabilistic relationship rat´s areas. captured areas, after its on posed better results. Conclusion: main contribution study incorporate minor delays achieved by applying before application. That supports neurophysiology dynamics essential suggested methodology support analysis
