Below is sample hyperscanning data from one subject (myself). For detailed information please refer to http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3254802 Name Email
This is a guest post by Andrew Gundran and Paul Mazaika, both working with NIRS in Stanford University. They did an interesting experiment comparing the light power between NIRSport and Octamon. We ran experiments to compare the emission signal stren
Back in 2010 we ran a simultaneous fMRI-NIRS experiment (see publication here). At that time we borrowed a 10m long optical fibers from Hitachi (Thank them!). The participants had to wear a NIRS cap (with probes) while lying in a fMRI scanner. And th
It’s often said that dark hair is bad for NIRS experiment because it absorbs more light. I heard this on day one when I started using NIRS back in 2008. I never got a chance to do a systematic experiment to compare hair colors and their effect
When you shop a new NIRS device, you want to compare all the different options in the market. One of the questions you may ask is: has anybody else been using the same device and how many? To this end, we compiled the number of publications citing so
I have a friend who has been using fMRI for more than 10 years and now a professor. He heard NIRS might be a good technology to measure human brain but knew little about it. So what is the difference between NIRS and fMRI? This is probably a common q
In concurrent NIRS-MRI experiments, you often need to know exactly where the NIRS probes are in the MRI iamges. In this case, a fiducial marker becomes important. In our 2011 publication titled “A quantitative comparison of NIRS and fMRI across

Back in 2009 we published a paper titled “Functional near infrared spectroscopy (NIRS) signal improvement based on negative correlation between oxygenated and deoxygenated hemoglobin dynamics“. In a nutshell, we found the oxy- and deoxy-H
