Objective. Spontaneous fluctuations of cerebral hemodynamics measured by functional magnetic resonance imaging (fMRI) are widely used to study the network organization brain. The temporal correlations among ultra-slow, <0.1 Hz across brain regions interpreted as connectivity maps and for diagnostics neurological disorders. However, despite interest narrowed in ultra-slow fluctuations, hemodynamic activity that exists beyond frequency range could contribute connectivity, which remains unclear.Approach. In present study, we have brain-wide human participants with near-infrared spectroscopy (fNIRS) a whole-head, cap-based high-density montage at sampling rate 6.25 Hz. addition, acquired resting state fMRI scans same group cross-modal evaluation maps. Then fNIRS data were deliberately down-sampled typical ∼0.5 resulted differential subject k-means clustering.Main results. Our diffuse optical topographical analysis revealed default mode (DMN) spontaneous deoxygenated oxygenated hemoglobin changes, remarkably resemble derived from participants. Moreover, shown aliased activities signals altered patterns, resulting hemodynamics.Significance.The results first time demonstrated broadly accessible modality can image resting-state posterior midline, prefrontal parietal structures DMN brain, consistent pattern fMRI.

Electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS) stand as state-of-the-art techniques for non-invasive neuroimaging. On a unimodal basis, EEG has poor spatial resolution while presenting high temporal resolution. In contrast, fNIRS offers better resolution, though it is constrained by its One important merit shared the that both modalities have favorable portability could be integrated into compatible experimental setup, providing compelling ground development of multimodal fNIRS-EEG integration analysis approach. Despite growing number studies using concurrent designs reported in recent years, methodological reference past remains unclear. To fill this knowledge gap, review critically summarizes status methods currently used studies, an up-to-date overview guideline future projects to conduct studies. A literature search was conducted PubMed Web Science through 31 August 2021. After screening qualification assessment, 92 involving data recordings analyses were included final review. Specifically, three categories analyses, including EEG-informed fNIRS-informed parallel identified explained with detailed description. Finally, we highlighted current challenges potential directions research.

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).

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. During measurement, only between happened through on-screen movement racing car, controlled by button presses both distinct roles, either controlling speed or direction car. Pairs were found to have elevated neural coupling alpha, beta, gamma frequency bands, compared performance matched false pairs. Higher synchrony was associated better momentary within dyads higher alpha mean across dyads.
