Restorative lighting–color ambience and experience in underground transit spaces: Evidence from VR and fNIRS

Subways are central to underground transit environments and subtly influence passengers’ moods and mental states, yet the effects of lighting and decorative design remain underexplored. This study employed a within-subject design in which 21 …

Multimodal Psychophysiological Analysis for Team Situation Awareness in Simulated Construction Environments

As robotics technologies are increasingly integrated into construction sites, cooperation between human workers and collaborative robots needs new strategies to address effective real-time teaming dynamics. Such teaming dynamics depend on strong Team …

Prefrontal Oxygenation During Supine-to-Stand Transitions in Head-out Water Immersion as a Ground-based Microgravity Analog: An fNIRS Pilot Study

Background: Thermoneutral head-out water immersion is used as a ground-based microgravity analog, but prefrontal hemodynamic responses to postural transitions in water are poorly characterized. This pilot study tested whether immersion attenuates the …

Quantification of cognitive load and usability in 3 percutaneous posterior spine surgical workflows using functional Near-Infrared Spectroscopy (fNIRS), Surgical Task Load Index (Surg-TLX) and modified System Usability Survey

Increase complexity in surgical workflows, with the introduction of digital interfaces and navigation, has the potential risk of introducing cognitive burden to the user. Understanding the effect of different surgical workflows on the user’s mental …

Cortical and Kinematic Correlates of Feedback-Based Head Stabilization During Treadmill Walking

Human motor control relies on the integration of sensory information to ensure stable and efficient move ment. Augmented feedback (aFB) provides external cues that can enhance movement execution, yet little is known about its neural correlates during …

Long-Term Tai Chi Exercise Slows the Degeneration of Functional Specialization Within Prefrontal Cortex in Older Adults During Precision Fitting Tasks

Objectives: This study investigated whether older adults with Tai Chi (TC) exercise exhibited similar dynamic postural stability and prefrontal cortex (PFC) activation as young adults during precision fitting tasks. Methods: Gender-matched groups of …

Prefrontal cortex activation during incremental inspiratory loading in healthy participants

We aimed to investigate whether changes in prefrontal cortex (PFC) oxyhemoglobin (O2Hb) and deoxyhemoglobin (HHb) associates with inspiratory muscle effort during inspiratory threshold loading (ITL) in healthy participants. Participants performed an …

An fNIRS Investigation of Discrete and Continuous Cognitive Demands During Dual-Task Walking in Young Adults

Introduction : Dual-task studies have demonstrated that walking is attention-demanding for younger adults. However, numerous studies have attributed this to task type rather than the amount of required to accomplish the task. This study examined four …

Response of the Cerebral Cortex to Resistance and Non-resistance Exercise Under Different Trajectories: A Functional Near-Infrared Spectroscopy Study

Background: At present, the effects of upper limb movement are generally evaluated from the level of motor performance. The purpose of this study is to evaluate the response of the cerebral cortex to different upper limb movement patterns from the …

Effects of Transcranial Direct Current Stimulation on Cycling Time Trial Performance and Prefrontal Cortex Activation

Background:Transcranial direct current stimulation (tDCS) is a neuromodulatory tech-nique that delivers low levels of a constant current via scalp electrodes to specificallytargeted areas of the brain. The effects of tDCS on whole-body exercise …

Greater habitual moderate-to-vigorous physical activity is associated with better executive function and higher prefrontal oxygenation in older adults

International physical activity guidelines recommend that older adults accumulate 150 min/week of moderate-vigorous physical activity (MVPA). It is unclear whether meeting this recommendation is associated with better higher-order cognitive functions …
