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
Update 2021/2/27: If you find griddata3 not working, try to change griddata3 to griddata. I was asked where to get nirs2img script. Here it is. The download link is at the bottom of this article. nirs2img is to create an image file from the input data. Then theimage file can be viewed by a

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
TL; DR Stork's AI Paper just got a major update: (a) Write a full paper in one go; (b) Accept file uploads (e.g. Word drafts, PowerPoint figures, and Excel results files); (c) More powerful AI with clearer logic, more concise language and better
Info "While peparing this work, the authors utilized Stork to check for language grammar errors and enhance readability." Recently, Juan Kou and her team from the Institute of Brain and Psychological Sciences at Sichuan Normal Univers
TL; DR A Nature survey of over 5,000 researchers shows that most people accept using AI tools for translation, proofreading, and even writing the first draft—if disclosed. But using AI for peer review is widely frowned upon. Transparency is key. AI w
