FNIRS and neurocinematics

In the overlap between Human-Computer Interaction (HCI) and Cinematics, sits an interest in physiological responses to experiences. Focusing particularly on brain data, Neurocinematics has emerged as a research field using Brain-Computer Interface …

Neurophysiological Variations in Food Decision-Making within Virtual and Real Environments

Simple lifestyle changes such as improving one's diet and getting sufficient exercise could significantly reduce the risk of developing obesity and related diseases such as diabetes, heart disease, stroke, and cancer. However, changing eating …

Evaluation of cortical neuroexcitation in urinary urgency using simultaneous near infrared spectroscopy of the brain and bladder with quantification of sensation

© 2019 SPIE Background: Overactivity of the bladder (OAB) affects 20% of people globally, causing urgency to void and incontinence of urine (UI)). OAB has a multi-factorial causation. Problematically current tests are invasive and provide limited …

Functional near infrared spectroscopy (fNIRS) in pigmented subjects: a maneuver to confirm sufficient transcutaneous photon transmission for measurement of hemodynamic change in the anterior cortex

© 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 research of the spectrophotometric method for the objective control of the auditory sense

One of the important tendencies of current clinical audiology is objectivization of hearing assessment. The presence of sensory perception is determined by neuronal activation of a certain area of the cerebral cortex caused by appropriate stimuli. It …

A comparison of mental and visual load resulting from semi-automated and conventional forest forwarding: An experimental machine simulation study

The purpose of the present study was to extend the knowledge of functional linkages between visual and mental load, performance, and prefrontal cortex (PFC) activity, during forestry forwarding work. Eleven healthy participants, range 21–51 years …

The effect of short time computer work on muscle oxygenation in presence of delayed onset muscle soreness

We aimed at investigating the effect of a short time low load repetitive task on the local muscle oxygenation kinetics in presence of delayed onset muscle soreness. Computer work was investigated as a model of low load repetitive task. Nine healthy …

Offspring of Mothers with Diabetes have Reduced Muscle Oxidative Capacity Measured by Near Infrared Spectroscopy

Optimization measurement of muscle oxygen saturation under isometric studies using FNIRS

Development of functional near infrared spectroscopy (fNIRS) technologies has advanced quantification signal using multiple wavelength and detector to investigate hemodynamic response in human muscle. These non-invasive technologies have been widely …

Is wireless functional near-infrared spectroscopy (fNIRS) 3D neuroimaging feasible to map human navigation in the real-world?

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 …

Towards NIRS-based hand movement recognition

This work reports on preliminary results about on hand movement recognition with Near InfraRed Spectroscopy (NIRS) and surface ElectroMyoGraphy (sEMG). Either basing on physical contact (touchscreens, data-gloves, etc.), vision techniques (Microsoft …

The effect of mental fatigue on sustained attention: an fNIRS study

Sustained attention is the ability to keep focused and vigilance for long time in external stimulation, which was crucial in safe-critical human-machine system. While the ability of sustained attention will decline because of mental fatigue, even …

The investigation of brain-computer interface for motor imagery and execution using functional near-infrared spectroscopy

Functional near-infrared spectroscopy (fNIRS), which can measure cortex hemoglobin activity, has been widely adopted in brain-computer interface (BCI). To explore the feasibility of recognizing motor imagery (MI) and motor execution (ME) in the same …

Investigating deep learning for fNIRS based BCI

Functional Near infrared Spectroscopy (fNIRS) is a relatively young modality for measuring brain activity which has recently shown promising results for building Brain Computer Interfaces (BCI). Due to its infancy, there are still no standard …

Optical diagnosis of acute scrotum in children

© 2015 SPIE.Background: Acute scrotum is a urologic condition defined by scrotal pain, swelling, and redness of acute onset. Prompt diagnosis and treatment are necessary to preserve testicular viability. The history and clinical symptoms reported are …

Optical diagnosis of testicular torsion: feasibility and methodology

Background: Torsion of the testis compromises blood flow through the spermatic cord; testicular ischemia results which if not diagnosed promptly and corrected surgically irrevocably damages the testis. Current diagnostic modalities aimed at …

Classification of mental tasks in the prefrontal cortex using fNIRS

Functional near infrared spectroscopy (fNIRS) is rapidly gaining interest in both the Neuroscience, as well as the Brain-Computer-Interface (BCI) community. Despite these efforts, most single-trial analysis of fNIRS data is focused on motor-imagery, …
