Electroencephalography (EEG) is a non-invasive neuroimaging technique that measures the electrical activity of the brain through electrodes placed on the scalp. EEG can be used for various research applications, including studying brain function and activity, identifying neurological disorders, and investigating the effects of drugs or other interventions on brain activity. EEG is particularly useful for studying brain activity in real-time and identifying the timing and location of brain activity associated with specific cognitive processes or behaviors. It can also be used in clinical settings to diagnose and monitor neurological disorders such as epilepsy, sleep disorders, and traumatic brain injuries. Additionally, EEG can be used to investigate the effects of various interventions, such as cognitive training or neurofeedback, on brain activity and function.
For surfers, catching the perfect wave can induce a state of pure ecstasy known as the “stoke”. But what’s happening in the brain during this ultimate ride? Wearable Sensing created a custom dry EEG system that measures brainwaves during surfing. They partnered with Red Bull to use this technology on professional surfers to uncover the neurophysiological aspects of surfing. The dry EEG system is worn on the head like a swimming cap, and it allows for the measurement of brain activity in real-time during surfing. By studying the brainwaves of surfers during their best rides, researchers hope to understand what goes on in the brain during moments of flow and peak performance, and ultimately unlock the secrets to achieving that elusive state of “stoke”.
In this study, wearable sensors and machine learning-based algorithms were used to predict hypoxia in-flight. The group used Wearable Sensing’s dry-EEG technology to collect sensor data from 85 participants during a two-phase study. Participants wore aviation flight masks, which regulated their oxygen intake while performing cognitive tests and simulated flying tasks. EEG data was collected and analyzed using principal component analysis and machine learning algorithms, including Naïve Bayes, decision tree, random forest, and neural network algorithms, to classify the data as normal or hypoxic. The results showed high sensitivity and specificity, indicating potential for developing a real-time, in-flight hypoxia detection system.
This paper proposes a protocol for assessing stress using wearable sensing technology, including Electroencephalography (EEG), Electrocardiography (ECG), and the Perceived Stress Scale, in combination with a Virtual Reality phobia induction setting. Wearable Sensing’s dry EEG technology is used to measure brain activity and investigate functional brain connectivity associated with stress. The proposed protocol can be expanded with the incorporation of machine learning algorithms for automatic stress level classification.

abstract = {Spatial envelop design of no-fly zone (NFZ) in urban air mobility (UAM) considers various factors and constraints. This study proposed a new NFZ boundary design method taking human factors into consideration. An obstacle avoiding experiment was conducted under 4 levels of distances including 104, 78, 52 and 26 m. Psychological, physiological and behavioral data were all recorded from the experiment to reflect stress levels of the participants under different building avoiding distances. Then a multi-criteria decision making (MCDM) framework was proposed to calculate the composite stress indicator (CSI) through the fusion of the three data sources. The two-order differences of CSI values were calculated to find out the turning point of stress. The result showed that CSIs from the 4 levels of distances were computed as 0.066, 0.100, 0.324 and 1.000. The 52-m building avoiding distance witnessed the abrupt change of CSI, indicating that 52-m separation can be regarded as a safety margin for establishing stress-driven no-fly zone. This contributes to the safe separation design in urban airspace.},

abstract = {Driving is evolving from a transportation task into a rich, multisensory experience in automated vehicles. This study developed and evaluated three multisensory solutions combining music with synchronized vibrotactile stimulation for autonomous driving contexts: safe (city driving), engagement (highway cruising), and entertainment (highway entry). Eighteen healthy adult drivers experienced three context–solution pairs presented in music only (M) and music with vibration (MV) modalities with simulated autonomous driving scenarios. Participants’ responses were measured using self-assessment manikin (SAM) ratings and electroencephalography (EEG). A significant main effect of modality showed that MV led to greater pleasure than M (EEG: p < 0.05; SAM: p < 0.05), with arousal showing a similar pattern (EEG: p < 0.05; SAM: p = 0.099). Behavioral data showed different emotional profiles across the three context−solution pairs (p < 0.001 for pleasure, arousal, and dominance), whereas the EEG contrast, which subtracted the video-only condition, showed no significant pair effect. These findings demonstrate that vibrotactile enhancement provides consistent emotional benefits across diverse driving contexts. Because each musical solution was paired with a unique driving scenario, these differences cannot be attributed solely to the music intervention. Future optimization of music and vibrotactile parameters may further enhance the autonomous driving experience.},

abstract = {Mindfulness has promise for enhancing emotion regulation in autistic individuals. Electroencephalography (EEG) emerges as an ideal, objective measure of neural responses before and after mindfulness practice. In a study with 39 autistic individuals, EEG analysis assessed the impact of mindfulness in the participants in a randomized controlled clinical trial of the Emotion Awareness and Skills Enhancement (EASE) program compared to a control group. Participants completed an affective Posner Task while wearing an EEG headset during two visits. In between visits, each participant either received EASE or active control therapy. Using random forest classifiers over the Post-Visit EEG features baseline corrected by Pre-Visit, the study achieved 88.48% to 91.86% accuracy in distinguishing EASE and Control groups under distress, non-distress, and neutral conditions. Linear mixed-effects models applied across the full EEG feature set revealed significant Visit × Feedback × Group interactions in central theta and midline and occipital beta band power, with post-hoc analyses indicating these effects were primarily driven by differential neural responses to rewarding versus unfavorable feedback. The EASE group demonstrated distinct pre-to-post changes in these features relative to the Control group, suggesting intervention-related modulation of neural systems supporting adaptive responses to emotionally meaningful feedback. These findings underscore mindfulness' positive influence on emotion regulation potentially showing its effects as neural oscillations matching the results from existing literature. Subgroup analysis based on Clinical Global Impressions threshold scores identified responders and non-responders with LME analyses confirming greater intervention-related EEG changes in EASE responders compared to Control responders.Our findings provide valuable insights into potential benefits of mindfulness-based interventions for autistic people, highlighting the neurophysiological effects of such programs.

abstract = {Emotion recognition from physiological signals typically treats emotions as discrete, static states rather than dynamic processes, limiting real-world affective computing applications. This dataset contains multimodal physiological recordings from 28 participants experiencing systematically designed emotional transitions in virtual reality. Participants viewed emotion-eliciting video stimuli across three emotional quadrants with transition periods between stimuli. Four physiological modalities were recorded: EEG (7 channels, 300 Hz), ECG (4 leads, 512 Hz), EMG (2 channels, 512 Hz), and GSR (3 channels, 10 Hz). The protocol employed a balanced incomplete block design across six emotional sequences. Statistical validation shows quadrant differentiation with 70% physiologically validated and 85% self-reported emotion induction success rates on average. Individual journey analysis indicates that participants traversed between 8.84% and 58.39% of the theoretical maximum cumulative distance on the valence–arousal plane, reflecting substantial individual differences in emotional responsivity. The dataset comprises 1.84 GB of original XDF recordings, 238 video-aligned physiological segments, and self-assessment ratings. This resource enables research in dynamic emotion recognition, and individual differences in responsivity during controlled emotional transitions.

In this study two subjects played a video game in which they had complementary roles, one player serving as a Bait to distract 5 enemy fortress and the other serving as a Shooter to destroy the fortress. Twenty-one pairs of subjects were analyzed. Critical events, destruction of the fortress and deaths of each player, evoked distinguishable P300-like responses from both players. Fortress kills could be best identified by combining the two EEG signals, while deaths could be best identified by focusing on the response of the player who died. Hidden semi-Markov models (HSMMs) achieved good identification of the events by combining information about the temporal distribution of these critical events with the conditional probability of the EEG activity. These findings indicate that we can track and improve by adaptively merging or selecting the signals from different team members.

abstract = {Real-time detection of motor intent using electroencephalography (EEG) with high accuracy remains a technical challenge for neurorehabilitation. Brain–computer interface-based neurofeedback training (BCI-NFT) paradigms need to detect pre-movement EEG to activate robotics or electrical stimulation nearly simultaneously with movement to promote neuroplasticity. We present a novel detection method commonly used in time-series forecasting (e.g., stock market trends), identifying crosses in fast (short) and slow (long) moving average windows to identify negative deflections in slow movement-related cortical potentials (MRCPs) or event-related desynchronization (ERD) within −400–+100 ms of movement onset. We recorded EEG data from the Cz electrode during our cued ankle dorsiflexion BCI-NFT paradigm in four adult participants, two neurotypical and two with cerebral palsy. Simulated real-time offline analyses demonstrated an 85.9% mean true positive rate and 14.1% false positive rate of detecting motor intent at a mean −182 ms from movement onset. We further evaluated whether the detection indicated a MRCP and/or ERD, with MRCP detected in 70–80% of trials in three participants, but high ERD detection (87%) instead in the other. Preliminary results indicate that this approach offers a straightforward, accurate, and well-timed method for real-time EEG detection during neurofeedback training and as a control signal for brain–computer interfaces.

By optimizing the trade-off between detection speed and accuracy, the proposed method significantly outperforms fixed-window baselines. Experimental results demonstrate an average offline accuracy of 86.54% and an Information Transfer Rate (ITR) of 115.04 bits/min, with comparable online performance (88.15% accuracy, 114.75 bits/min ITR).

In an exploratory, placebo-controlled, within-subjects, electroencephalography (EEG), and magnetic resonance imaging (MRI) study in 28 healthy, entirely psychedelic-naive participants, anatomical and functional brain changes are detected from one-hour to one-month after a single high-dose (25 mg) of psilocybin. Increases in cognitive flexibility, psychological insight, and well-being are seen at one-month. Diffusion tensor imaging (DTI) done before and one-month after 25 mg psilocybin reveals decreased axial diffusivity bilaterally in prefrontal-subcortical tracts that correlate with decreases in brain network modularity (fMRI) over the same month. Enduring functional brain changes are largely absent, but network modularity change (numerical decrease) negatively correlates with well-being change (significant increase), in line with previous findings in depression. Increased cortical signal entropy (EEG) at 1- and 2-hours post-dosing predicts improved psychological well-being at one-month. Next-day psychological insight mediates the entropy to well-being relationship. All effects are exclusive to 25 mg psilocybin; no effects occur with a 1 mg psilocybin placebo.},

abstract = {Intro
Virtual reality (VR)–based counseling is an emerging modality for digital mental health, offering immersive environments that can be experimentally controlled to test how social cues shape responses to therapeutic content. However, limited research has examined how counselor avatar gender and scenario severity jointly influence observers’ affective outcomes and neurophysiological dynamics during vicarious exposure to VR counseling.
Methods
Fifty-one female college students (ages 18‒25) from South Korea were randomly assigned to a 2 × 2 factorial design: counselor avatar gender (male vs. female) × scenario severity (mild-stressor vs. severe-crisis). Participants observed a scripted VR counseling scenario (∼12 min analyzable exposure; ∼20 min total including setup/instructions). Pre- and post-session assessments included State-Trait Anxiety Inventory (STAI-S; total scores 20–80) and Warwick-Edinburgh Mental Well-Being Scale (WEMWBS; total scores 14–70). Relative beta power (13–30 Hz) was measured via EEG (Lovibond and Lovibond, 1995).
Results
A 2 × 2 ANOVA on post-session STAI-S total scores revealed a significant counselor gender × scenario severity interaction, F(1,47) = 8.50, p = 0.005, η2 = 0.153. Participants observing severe-crisis scenarios with female counselors reported highest anxiety (M = 72.0, SD = 9.8) versus male counselors (M = 48.8, SD = 18.8), t(22) = 3.58, p = 0.002, d = 1.50. For WEMWBS, severe-scenario participants showed greater well-being with female counselors (M = 52.1, SD = 10.6) than male (M = 40.0, SD = 12.0), t(22) = 2.68, p = 0.014, d = 1.08. EEG revealed no main effect of group (p = 0.754), but a significant Group × Channel interaction (p = 0.014) in frontal-temporal regions.
Conclusion.
Counselor-avatar gender cues and scenario severity shaped observers’ immediate affective and neurophysiological responses to simulated VR counseling in complex ways. Elevated anxiety during severe-crisis content—particularly when observing a female-coded counselor avatar—may reflect intensified engagement with distressing material rather than simple discomfort. Neurophysiological findings indicate phase-dependent changes in arousal-related processing, with condition effects appearing regionally localized rather than global. These findings may inform future research on avatar design in digital mental health environments and motivate direct comparisons between observational and interactive VR counseling paradigms.},
