Categorization and discrimination of human and non-human primate affective vocalizations: Investigation of frontal cortex activity through fNIRS
Previous research has highlighted the involvement of frontal regions in human participants while they engaged in the explicit decoding, such as categorization (A vs B) and discrimination (A vs non-A), of affective signals. Given its adaptive value …
Sex Differences in Sustained Attention Performance and Neuromuscular Fatigue During an Intense Cognitive-Motor Dual Task in Normoxia and Hypoxia
Purpose: As females have been shown to exhibit greater resistance to fatigue in muscles but lower hypoxia-induced cerebral oxygen saturation during whole-body exercise, this study was conducted to assess their responses to intense cognitive-motor …
The effect of transcranial pulse current stimulation on the accumulation of exercise-induced fatigue in college students after moderate intensity exercise evidence from central and peripheral sources
Objective: To investigate the intervention effect of cranial pulse current stimulator (tPCS) on fatigue accumulation after moderate-intensity exercise by using blood analysis and functional near-infrared spectroscopy, and to analyze the type and …
Effects of Internal and External Cues on Brain Activity and Gait in Parkinson’s Disease: Findings From BARC-PD
Background Internal and external cueing strategies are often applied to alleviate gait deficits in Parkinson’s disease (PD). However, it remains unclear which type of cueing strategy is most effective at different disease stages. The underlying …
A biological phenotype of suicide attempt in adolescents with nonsuicidal self-injury: a machine-based learning approach
Suicide attempts (SA) are a common risk in adolescents with non-suicidal self-injury (NSSI). In the present study, we investigated whether a set of biological markers contributed (above clinical features) to the distinction of adolescents with NSSI …
Acute effects of inspiratory muscle warm-up on muscle oxygenation, perceived exertion and prefrontal cortical activation
Background: Knee osteoarthritis (KOA) is a chronic degenerative disease characterized primarily by pain and joint dysfunction, especially during level and stair walking. Although traditionally classified as a peripheral joint disease, emerging …
Psychophysiological research in real-world environments: methodological perspectives from the SLU Multisensory Outdoor Laboratory
Growing evidence demonstrates the importance of environmental quality for human health and wellbeing. Environmental psychology can inform planning and design of future environments, but previous research often used simulated settings, limiting …
Public Safety Personnel Readiness Prediction: A Hybrid Model of Neurophysiological and Psychometric Data
Personnel selection and agent readiness are critical priorities for defense organizations, particularly in ensuring staff are adequately prepared for high-stakes environments such as public safety and military operations. Readiness assessments …
Verbal arm swing instructions alter arm-leg interlimb coordination but not prefrontal cortex hemodynamics in people with Parkinson's disease
Verbal instructions related to the arm swing amplitude and velocity change step gait behavior in people with Parkinson's disease (PwPD) and neurotypical individuals. However, how verbal instructions related to upper limb act on interlimb coordination …
A MATLAB-based tool for converting fNIRS time-series data to Homer3-compatible formats
Functional Near-Infrared Spectroscopy (fNIRS) is increasingly used in cognitive neuroscience and clinical research, yet preprocessing raw time-series data remains challenging. We introduce a lightweight MATLAB tool to automate the conversion of fNIRS …
Nigrostriatal dopaminergic integrity in relation to prefrontal cortex activity and gait performance during dual-task walking in older adults
Greater walking automaticity facilitates maintenance of gait speed without prefrontal cortex (PFC) resources. Brain aging may cause shifts to more attentional gait with greater engagement of the PFC. Nigrostriatal dopaminergic integrity likely …
Understanding the Unexplored: A Review on the Gap in Human Factors Characterization for Industry 5.0
The integration of neurophysiological techniques into Industry 5.0 represents a transformative approach to assessing human factors in real-world operational settings. This study presents a systematic review of existing literature to evaluate the …
Improving locomotor performance with motor imagery and tDCS in young adults
The study aimed to assess the feasibility and potential efficacy of a non-motor intervention utilizing motor imagery (MI) and transcranial direct current stimulation (tDCS) to enhance motor function. The research involved a double-blind, randomized, …
Pleasant Touch: behavioural and hemodynamic responses to a protocol for systematic assessment of tactile stimulation.
Pleasant touch is a form of tactile stimulation mediated by tactile C afferent fibres. It involves the encoding of the emotional value associated with tactile stimulation and subserves important social functions. Although pleasant touch has gathered …
The effect of distraction and feedback on prefrontal cortex activity and balance in middle-aged adults: A functional near-infrared spectroscopy pilot study
Maintaining balance while simultaneously performing other tasks is common during everyday activities. However, this dual-tasking (DT) divides attention and increases cognitive demand, which can be detrimental to stability in older adults. It is …
Thoracic load carriage impairs the acute physiological response to hypoxia in healthy males
To assess the impact of thoracic load carriage on the physiological response to exercise in hypoxia. Healthy males (n = 12) completed 3 trials consisting of 45 min walking in the following conditions: (1) unloaded normoxia (UN; FIO2:20.93%); (2) …
Advanced Machine Learning Approaches for Classifying Parkinson's Disease Using fNIRS Data from Gait Analysis
This study investigates the use of machine learning to differentiate between Parkinson's patients and healthy individuals using functional near infrared spectroscopy (fNIRS) signals collected during walking. fNIRS data, which monitor brain activity, …
