Employing cardiac and respiratory features extracted from fNIRS signals for mental workload classification

Functional Near-Infrared Spectroscopy (fNIRS) is gaining popularity in detection and classification of cognitive and emotional states. In addition to hemodynamic responses arising from functional activity changes in the brain areas of interest, fNIRS …

fNIRS signal quality estimation by means of a machine learning algorithm trained on morphological and temporal features

Functional near infrared spectroscopy (fNIRS) is used for brain hemodynamic assessment. Cortical hemodynamics are reliably estimated when the recorded signal has a sufficient quality. This is acquired when fNIRS optodes have proper scalp coupling. A …

Short report on research trends during the COVID-19 pandemic and use of telehealth interventions and remote brain research in children with autism spectrum disorder

Following the outbreak of the COVID-19 pandemic, the delivery of face-to-face (F2F) therapeutic interventions and neuroimaging assessments for children with autism spectrum disorder has been disrupted. To resume interventions and assessments, many …

Cerebral oxygenation responses to head movement measured with near-infrared spectroscopy

Motion is disruptive to neuroimaging methods. Motion artefacts range from large amplitude and short frequency spikes to drifts in amplitude causing cofounds in the analysis or completely invalidating any analysis, leading to epoch exclusion of data. …

Fugl-Meyer hand motor imagination recognition for brain–computer interfaces using only fNIRS

As a relatively new physiological signal of brain, functional near-infrared spectroscopy (fNIRS) is being used more and more in brain–computer interface field, especially in the task of motor imagery. However, the classification accuracy based on …

Perceived Mental Workload Classification Using Intermediate Fusion Multimodal Deep Learning

A lot of research has been done on the detection of mental workload (MWL) using various bio-signals. Recently, deep learning has allowed for novel methods and results. A plethora of measurement modalities have proven to be valuable in this task, yet …

Exploring the brain activity related to missing penalty kicks: an fNIRS study

Despite having a near perfect control over a ball, professional football/soccer players often miss penalties. Psychological factors (anxiety) are often named as explanations for these misses. A commonly used terminology is 'choking under pressure'. …

Signal quality index: an algorithm for quantitative assessment of functional near infrared spectroscopy signal quality

We propose the signal quality index (SQI) algorithm as a novel tool for quantitatively assessing the functional near infrared spectroscopy (fNIRS) signal quality in a numeric scale from 1 (very low quality) to 5 (very high quality). The algorithm …

Using Functional Near-Infrared Spectroscopy to Detect a Fear of Heights Response to a Virtual Reality Environment

Over the past decades, virtual reality (VR) technology has gained significant popularity and interest, both in research as well as on the consumer market. One promising application area of VR is virtual reality exposure therapy (VRET), which treats …

Brain activation in virtual reality for attention guidance

Virtual Reality (VR) not only offers great opportunities in terms of entertainment, it is also widely applicable in the field of attention guidance, medicine and psychology. The distinction between VR and ordinary media is the 360$$^∘ $$ - also known …

Simultaneous functional near infrared spectroscopy of the brain and bladder

Background: Worldwide 2.3 billion individuals are affected by bladder disease. The current evaluative test is invasive, associated with complications and often declined. Non-invasive evaluation of bladder hemodynamics using continuouswave …

Brief Report: Classification of Autistic Traits According to Brain Activity Recoded by fNIRS Using $ε$-Complexity Coefficients

Individuals with ASD have been shown to have different pattern of functional connectivity. In this study, brain activity of participants with many and few autistic traits, was recorded using an fNIRS device, as participants preformed an interpersonal …

Role of exercise, cold, and the biological clock on energy balance in humans: The ACTIBATE study

Cold exposure has been proposed as a potential tool to face obesitysince it is able to increase energy expenditure (i.e., cold induced thermogenesis –CIT). This increase is partially mediated by brown adipose tissue (BAT). Nevertheless, little is …
