In this study, we propose a method to enhance cognitive vigilance and mitigate mental stress in the workplace. We designed an experiment induce by putting participants through Stroop Color-Word Task (SCWT) under time constraint negative feedback. Then, used 16 Hz binaural beats auditory stimulation (BBs) for 10 minutes stress. Functional Near-Infrared Spectroscopy (fNIRS), salivary alpha-amylase, behavioral reactions were determine level. The level of was assessed using reaction stimuli (RT), accuracy target detection, directed functional connectivity based on partial coherence, graph theory measures, laterality index (LI). discovered that BBs mitigated substantially increasing detection 21.83% ( p <0.001) decreasing alpha amylase levels 30.28% (p<0.01). analysis LI results indicated decreased information flow from left right prefrontal cortex stress, whereas had major impact enhancing mitigating via boosting network dorsolateral ventrolateral cortex.

Magnetoencephalography (MEG) plays a pivotal role in the diagnosis of brain disorders. In this review, we have investigated potential MEG applications for analysing The signal-to-noise ratio (SNRMEG = 2.2 db, SNREEG < 1 db) and spatial resolution (SRMEG 2–3 mm, SREEG 7–10 mm) is higher than EEG, thus potentially facilitates accurate monitoring cortical activity. We found that direct electrophysiological signals reflected physiological status neurological disorders play vital disease diagnosis. Single-channel connectivity, as well network analysis, using data acquired during resting state given task has been used such epilepsy, Alzheimer’s, Parkinsonism, autism, schizophrenia. workflow its therapeutic planning are also discussed. forecast computer-aided algorithms will prominent prediction diseases future. outcome narrative review aid researchers to utilise diagnostics.

Abstract Mental fatigue (MF) can impair pilots’ performance and reactions to unforeseen events is therefore an important concept within aviation. The physiological measurement of MF, especially with EEG and, in recent years, fNIRS, has gained much attention. However, a systematic investigation comparison the measurements seldomly done. We induced MF via time on task during 90-min simulated flight collected concurrent EEG-fNIRS, self-report data from 31 participants. While their subjective increased linearly, participants were able keep stable over course experiment. showed early increase levelling parietal alpha power slower, but steady frontal theta power. No consistent trend could be observed fNIRS data. Thus, more research needed understand its possibilities limits for assessment, combination advisable compare validate results. Until then, remains better choice continuous assessment cockpit applications because high sensitivity transition alert fatigued, even before impaired.

Functional Near-Infrared Spectroscopy (fNIRS) is an innovative and promising neuroimaging modality for studying brain activity in real-world environments. While fNIRS has seen rapid advancements hardware, software, research applications since its emergence nearly 30 years ago, limitations still exist regarding all three areas, where existing practices contribute to greater bias within the neuroscience community. We spotlight through lens of different end-application users, including unique perspective a manufacturer, report challenges using this technology across several disciplines populations. Through review domains utilized, we identify address presence bias, specifically due restraints current technology, limited diversity among sample populations, societal prejudice that infiltrates today's research. Finally, provide resources minimizing application agenda future use equitable, diverse, inclusive.

A growing number of social interactions are taking place virtually on videoconferencing platforms. Here, we explore potential effects virtual observed behavior, subjective experience, and neural "single-brain" "interbrain" activity via functional near-infrared spectroscopy neuroimaging. We scanned a total 36 human dyads (72 participants, males, females) who engaged in three naturalistic tasks (i.e., problem-solving, creative-innovation, socio-emotional task) either an in-person or (Zoom) condition. also coded cooperative behavior from audio recordings. reduced conversational turn-taking during the Given that was associated with other metrics positive interaction (e.g., cooperation task performance), this measure may be indicator prosocial interaction.

Functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI) both measure the hemodynamic response, so modalities are expected to have a strong correspondence in regions of cortex adjacent scalp. To assess whether fNIRS can be used clinically manner similar fMRI, 22 healthy adult participants underwent same-day fMRI whole-head testing while they performed separate motor (finger tapping) visual (flashing checkerboard) tasks. Analyses were conducted within across subjects for each approach, significant task-related activity compared on cortical surface.
