The following script is to determine is a channel (or voxel) survives the FDR corrected threshold. Assume you have 48 channels and you already calculated the (uncorrected) p-value of each channel. You put it into an array called p. Now you want to kn
Finger tapping is probably the most used task in brain imaging studies (fMRI and NIRS). The task is simple and elicits robust brain signal in the motor cortex. We always use it to test new devices or develop a new method. If you want to control your

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
When I was a graduate student at Baylor College of Medicine, I found myself often in an embarrassing situation — I felt completely lost when my fellow graduate students heatedly discussed a paper in our field but I never heard of this publicati
我在Baylor College of Medicine读研究生的时候经常遇到一种尴尬局面，就是同学们在热烈讨论本领域某篇文献的时候，我一脸茫然 — 因为我压根就不知道这篇文章。回头Pub
