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 …

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 …

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. …

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 …

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 …

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'. …

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 …

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 …

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 …

Dementia cognitive decline vascular cognitive impairment functional near infrared spectroscopy (fNIRS) A B S T R A C T The commonest causes of dementia are Alzheimer's disease and vascular cognitive impairment. Although these conditions have been …

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 …

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 …

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 …

This mini-review is aimed at briefly summarizing the present status of functional near-infrared spectroscopy (fNIRS) and predicting where the technique should go in the next decade. This mini-review quotes 33 articles on the different fNIRS basics …

© 2019 SPIE Background: A requisite for fNIRS studies of cortical blood flow is that sufficient photons are transmitted transcutaneously for the fluctuations in cerebral hemoglobin oxygenation that occur during neuronal activation to be detected. …

The development of novel miniaturized wireless and wearable functional near-infrared spectroscopy (fNIRS) devices has paved the way for new functional brain imaging that could revolutionize the cognitive research fields. Over the past few decades, …

The past few decades have seen a rapid increase in the use of functional near-infrared spectroscopy (fNIRS) in cognitive neuroscience. This fast growth is due to the several advances that fNIRS offers over the other neuroimaging modalities such as …

Real-time maps (with temporal and spatial resolution: 1–10 Hz and $∼$1 cm, respectively) of cortical activation can be obtained by functional near-infrared spectroscopy (fNIRS), which noninvasively measures cortical hemodynamic changes (as oxygenated …
