Multimodal functional near-infrared spectroscopy–functional magnetic resonance imaging (fNIRS–fMRI) studies have been highly beneficial for both the fNIRS and fMRI field as, for example, they shed light on the underlying mechanism of each method.

PURPOSE: Motion estimation is an essential step in functional Magnetic Resonance Imaging (fMRI) preprocessing. Usually, fMRI processing software packages (e.g. FSL and AFNI) automatically estimate motion parameters in order to counteract the effects

Systemic low-frequency oscillations (sLFOs) are non-neuronal oscillations at 0.01–0.15 Hz. These sLFOs travel through the entire body and the brain with symmetrical (across the midline of the body) and highly predictable delays, where they can be o

Cardiac signal contamination has long confounded the analysis of blood-oxygenation-level-dependent (BOLD) functional magnetic resonance imaging (fMRI). Cardiac pulsation results in significant BOLD signal changes, especially in and around blood vesse

A “carpet plot” is a 2-dimensional plot (time vs. voxel) of scaled fMRI voxel intensity values. Low frequency oscillations (LFOs) can be successfully identified from BOLD fMRI and used to study characteristics of neuronal and physiological activi

Concussion, or mild traumatic brain injury (mTBI), accounts for ∼80% of all TBIs across North America. The majority of mTBI patients recover within days to weeks; however, 14–36% of the time, acute mTBI symptoms persist for months or even years a

It is widely known that blood oxygenation level dependent (BOLD) contrast in functional magnetic resonance imaging (fMRI) is an indirect measure for neuronal activations through neurovascular coupling. The BOLD signal is also influenced by many non-n

Purpose Functional MRI (fMRI) blood–oxygen level–dependent (BOLD) signals result not only from neuronal activation, but also from nonneuronal physiological processes. These changes, especially in the low-frequency domain (0.01–0.2 Hz), can sign

With the rapid increase in new fNIRS users employing commercial software, there is a concern that many studies are biased by suboptimal processing methods. The purpose of this study is to provide a visual reference showing the effects of different pr

Functional magnetic resonance imaging (fMRI) is a popular brain imaging modality with a wide range of use in clinical research. A major problem with fMRI signals is the presence of systemic physiological fluctuations in the low frequency range (
