Diagnostic machine learning applications on clinical populations using functional near infrared spectroscopy: a review

Functional near-infrared spectroscopy (fNIRS) and its interaction with machine learning (ML) is a popular research topic for the diagnostic classification of clinical disorders due to the lack of robust and objective biomarkers. This review provides …

Identification of Cognitive Workload during Surgical Tasks with Multimodal Deep Learning

The operating room (OR) is a dynamic and complex environment consisting of a multidisciplinary team working together in a high take environment to provide safe and efficient patient care. Additionally, surgeons are frequently exposed to multiple …

Multilevel Pain Assessment with Functional Near-Infrared Spectroscopy: Evaluating ΔHBO2 and ΔHHB Measures for Comprehensive Analysis

Assessing pain in non-verbal patients is challenging, often depending on clinical judgment which can be unreliable due to fluctuations in vital signs caused by underlying medical conditions. To date, there is a notable absence of objective diagnostic …

Adaptative computerized cognitive training decreases mental workload during working memory precision task. A preliminary fNIRS study.

With the growing concern for the health of ageing populations, much research continues to look at the impact of cognitive training, particularly in relation to cognitive decline. We sought to use novel techniques, including augmented reality and …

A stepwise approach for functional near infrared spectroscopy measurement during natural bladder filling

Background: Functional near infrared spectroscopy (fNIRS) is a versatile, noninvasive, and inexpensive tool that can be used to measure oxyhemoglobin (O2Hb) changes in the cortical brain caused by increasing bladder sensation during filling in …

Distinct age-related brain activity patterns in the prefrontal cortex when increasing cognitive load: A functional near-infrared spectroscopy study

Researchers have long observed distinct brain activity patterns in older adults compared with younger adults that correlate with cognitive performance. Mainly, older adults tend to show over-recruitment of bilateral brain regions during lower task …

Neuroimaging, wearable sensors, and blood-based biomarkers reveal hyperacute changes in the brain after sub-concussive impacts

Impacts in mixed martial arts (MMA) have been studied mainly in regard to the long-term effects of concussions. However, repetitive sub-concussive head impacts at the hyperacute phase (minutes after impact), are not understood. The head experiences …

At-home computerized executive-function training to improve cognition and mobility in normal-hearing adults and older hearing aid users: a multi-centre, single-blinded randomized controlled trial

Abstract Background Hearing loss predicts cognitive decline and falls risk. It has been argued that degraded hearing makes listening effortful, causing competition for higher-level cognitive resources needed for secondary cognitive or motor tasks. …

Feeling Positive? Predicting Emotional Image Similarity from Brain Signals

The present notion of visual similarity is based on features derived from image contents. This ignores the users' emotional or affective experiences toward the content, and how users feel when they search for images. Here we consider valence, a …

Abnormal Frontal Brain Activation in Patients With Asymptomatic Carotid Artery Stenosis

Background Emerging evidence suggests that asymptomatic carotid artery stenosis (ACAS) is associated with cognitive and mobility dysfunction, and that this may be secondary to cerebral hemodynamic changes. Functional near-infrared spectroscopy …

Locally contextualized psycho-physiological wellbeing effects of environmental exposures: An experimental-based evidence

Geographically-distributed urban environment contexts affect human psychological wellbeing through the real-time interactions between individuals and their surroundings. Recent field experiments have become particularly interesting in using wearable …

Affective Relevance: Inferring Emotional Responses via fNIRS Neuroimaging

Information retrieval (IR) relies on a general notion of relevance, which is used as the principal foundation for ranking and evaluation methods. However, IR does not account for more a nuanced affective experience. Here, we consider the emotional …

An fNIRS investigation of novel expressed emotion stimulations in schizophrenia

Abstract Living in high expressed emotion (EE) environments tends to increase the relapse rate in schizophrenia (SZ). At present, the neural substrates responsible for high EE in SZ remain poorly understood. Functional near-infrared spectroscopy …

C-STIM: Protocol for a randomized, single-blind, crossover study of cerebellar repetitive transcranial magnetic stimulation (rTMS) for postural instability in people with progressive supranuclear palsy (PSP)

Background Methods for modulating the cerebellum with transcranial magnetic stimulation (TMS) are well established, and preliminary data from our group and others has shown evidence of transient improvements in balance after cerebellar repetitive …

Cortical activation during fine motor movement of Parkinson’s disease patients using fNIRS (P4-11.013)

Objective: To determine if there is functional differences in activation of motor cortex measured by funciontal near-infrared spectroscopy (fNIRS) on Parkinson’s disease (PD) patients compared to healthy people. Background: PD is one of the …

Crowdsourcing Affective Annotations via fNIRS-BCI

Affective annotation refers to the process of labeling media content based on the emotions they evoke. Since such experiences are inherently subjective and depend on individual differences, the central challenge is associating digital content with …

Defecation enhances cerebral perfusion and delays fatigue in elite triathletes

Background Rectal distension increases regulatory burden to autonomic nervous system in the brain. Purpose To determine the effect of rectal defecation on endurance performance and blood supply to the prefrontal brain and sub-navel regions of elite …

Treadmill Walking Maintains Dual-task Gait Performance and Reduces Frontopolar Cortex Activation in Healthy Adults

Studies examining dual-task gait (DTG) have used varying conditions such as overground or treadmill walking, however it is not known whether brain activation patterns differ during these conditions. Therefore, this study compared oxyhaemoglobin …

Counter-stereotype intervention for construction and demolition waste recycling products: A functional near infrared spectroscopy study

The generation and stock of construction and demolition (C&D) waste is increasing, which makes the environmental and economic problems serious. In recent years, China has also launched many policies to encourage and guide C&D waste recycling. …
