Can you find any pattern in the two signals, green and blue? The blue signal is the brain wave (measured by NIRS) of a person when he is pressing some buttons (the timing of button pressing is shown i
Wavelet transform coherence (WTC) is a method for analyzing the coherence and phase lag between two time series as a function of both time and frequency (Chang and Glover 2010). Here I played with it
SVM is mostly commonly used for binary classifications. But one branch of SVM, SVM regression or SVR, is able to fit a continuous function to data. This is particularly useful when the predicted varia
Note: The following article is a guest post by Vanessa Reindl from University Hospital RWTH Aachen, Germany. She made our original hyperscanning game more interesting for children studies. She is very generous for sharing her experience as well as th
xjView is a viewing program to visualize fMRI images. It can also be used to visualize fNIRS data if you convert the fNIRS activation data to a brain image. Today, we released version 10.0. The main updates are: The AAL version is updated to AAL3v1 I

Today I downloaded SPM 12 latest version, and when I tried to start it complained: Error using narginchk (line 10) too many input arguments This error is caused by the conflict of multiple narginchk functions. To find out where they are, type >>
Let’s be frank. Compared to fMRI, NIRS has a number of intrinsic weaknesses. The signal to noise ratio is lower, the spatial resolution is (10x) lower, it can’t measure the deep brain, and it only covers a portio
