NIRS Effect of Physiology on Mapping Resting State Networks + fNIRS

NIRS Effect of Physiology on Mapping Resting State Networks + fNIRS

In this webinar, Androu Abdalmalak and Sergio Novi discussed their recent publication titled " Effects of Systemic Physiology on Mapping Resting-State Networks Using Functional Near-Infrared Spectroscopy". This work investigates the effects of systemic physiological noise on extracting resting-state networks with fNIRS. In the first part of this webinar, Androu explained the importance of extracting meaningful resting-state networks at the single-subject level, particularly as it pertains to their ongoing research aimed at using fNIRS to predict outcomes in patients with acute brain injuries. 

NIRS-fNIRS The Neuroergonomics of Exercise and Neuromuscular Fatigue

NIRS-fNIRS The Neuroergonomics of Exercise and Neuromuscular Fatigue

The cortex and motor areas of the brain are responsible for voluntary muscle control, and determination of the “safe limit” of exercise performance. Moreover, neuromuscular performance in older adults is exacerbated under stress and is characterized by shorter endurance time, greater perceived effort, lower force steadiness, and higher electromyographic activity. But the neural mechanisms of exercise under stress are not well understood. In this talk, Oshin explored the neural correlates of exercise and how stress influences these correlates. For this, they used effective connectivity, which quantifies the influence of one brain region over the other, to understand how the prefrontal and motor areas of the brain influence each other during exercise performance under stress.

NIRS-fNIRS Image Reconstruction in fNIRS

NIRS-fNIRS Image Reconstruction in fNIRS

In this webinar, Dr. Ted Huppert talked about how to perform image reconstruction and use digitization information in the Brain AnalzyIR toolbox. Image reconstruction is one of the most important topics in neuroimaging. It gives more information about where the measured signal is coming from and helps with the correct interpretation of the dataset. Dr. Ted Huppert is an Associate Professor of Electrical and Computer Engineering at the University of Pittsburgh. He has authored over 80 publications on fNIRS applications and method developments and is the creator of the AnalyzeIR NIRS-toolbox.

NIRS-fNIRS Physiological Considerations During Multimodal fNIRS

NIRS-fNIRS Physiological Considerations During Multimodal fNIRS

In this talk, Joel Burma of the Cerebrovascular Concussion Laboratory/Experimental Imaging Centre at the University of Calgary, talks about using fNIRS multimodal imaging. The concurrent use of physiological sensors in fNIRS experiments has grown in recent years. In this open webinar Joel discusses pitfalls, methodological advancements, and future directions for multimodal research using fNIRS + physiological measurements.

NIRS-fNIRS Image Reconstruction High Density fNIRS

NIRS-fNIRS Image Reconstruction High Density fNIRS

We are pleased to welcome Dr. David Boas to share with us his expert knowledge on the topic of High-Density fNIRS (HD-fNIRS / DOT). HD-fNIRS is a methodology that employs high-density arrays with short, medium and long channels. Overlapping measurements with multiple source-detector distances can improve spatial resolution, depth and lateral specificity, and can enable the tomographic (image) reconstruction of cerebral activation. In this two part webinar series, we will go the full circle of HD fNIRS: From practically setting up, conducting, and analyzing HD-fNIRS experiments using Dr. Boas' open source fNIRS analysis toolboxes AtlasViewer and Homer3 together with NIRx' NIRSport2 systems and Aurora/NIRSite software.

NIRS-fNIRS Positioning Optodes fNIRS in Infants - from Data Collection to Preprocessing
NIRS-fNIRS Positioning Optodes fNIRS in Infants - from Data Collection to Preprocessing
The talk covers different aspects related to infant studies; in particular, it will start with an overview of approaches for the design of the optode array, with examples from literature as well as a couple practical examples of tools that can be used to this end. Relatedly, it will discuss strategies for anatomical localization of the designed array. Following, the talk, Dr. Gemignani will focus on the data pre-processing stage, including the assessment of raw data quality as well as best approaches to design a routine that optimally suits the study characteristics (e.g., number of trials) while accurately recovering the HRF (Gemignani and Gervain 2021).
