Measuring visual cortical oxygenation in diabetes using functional near-infrared spectroscopy [PDF]

open access: yes, 2018
Aims: Diabetes mellitus affects about 6% of the world’s population, and the chronic complications of the disease may result in macro- and micro-vascular changes.

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa [PDF]

open access: yes, 2011
Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in

Improved physiological noise regression in fNIRS: a multimodal extension of the General Linear Model using temporally embedded Canonical Correlation Analysis [PDF]

open access: yes, 2020
For the robust estimation of evoked brain activity from functional Near-Infrared Spectroscopy (fNIRS) signals, it is crucial to reduce nuisance signals from systemic physiology and motion.

Using Functional Near Infrared Spectroscopy (fNIRS) to study dynamic stereoscopic depth perception [PDF]

open access: yes, 2016
The parietal cortex has been widely implicated in the processing of depth perception by many neuroimaging studies, yet functional near infrared spectroscopy (fNIRS) has been an under-utilised tool to examine the relationship of oxy- ([HbO]) and de ...

Functional differentiation within the monkey cortex as revealed by near-infrared spectroscopy [PDF]

open access: yes, 2008
The role of prefrontal cortex in working memory (WM) is well established. However, questions remain regarding the topography and “domain-specific differentiation” of different types of information processing in the cortex.

A Systematic Comparison of Motion Artifact Correction Techniques for Functional Near-Infrared Spectroscopy

open access: yesFrontiers in Neuroscience, 2012
Near-infrared spectroscopy (NIRS) is susceptible to signal artifacts caused by relative motion between NIRS optical fibers and the scalp. These artifacts can be very damaging to the utility of functional NIRS, particularly in challenging subject groups ...

Contribution of speckle noise in near-infrared spectroscopy measurements [PDF]

open access: yes, 2019
Near-infrared spectroscopy (NIRS) is widely used in biomedical optics with applications ranging from basic science, such as in functional neuroimaging, to clinical, as in pulse oximetry.

Design and synthesis of aromatic molecules for probing electric-fields at the nanoscale [PDF]

open access: yes, 2015
We propose using halogenated organic dyes as nanoprobes for electric field and show their greatly enhanced Stark coefficients using density functional theory (DFT) calculations.
