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
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
This is a guest post by Ning Liu from Stanford University. – A basic block design includes two conditions: task condition and control condition. The two conditions present alternatively, thus is also called ‘AB block’ (Fig. 1A). This design assumes t
This is a guest post by Ning Liu from Stanford University. — For someone who has no imaging background and just began to use fNIRS, s/he might be surprised to find out that the imaging study design is so different with study designs in other fi
If you are a newcomer in the NIRS field, you may wonder who are the experts in this field. You might know a few already – for example your boss. But who else are there and where they are? We developed “Find Experts” app to quickly f
From 2000 and 2010, the number of PubMed citations had grown from half million to 1 million. Today we see ~3,000 new papers everyday! Year Number 2016 1258608 2015 1253004 2014 1201621 2013 1146180 2012 1085504 2011 1017939 2010 940347 2009 875631 20
Near infrared spectroscopy (NIRS) is an increasingly popular technology in brain imaging research. Compared to fMRI, NIRS can be used for more naturalistic experiments, including face to face communication, natural body movements, sports, infants, an
In this version, we modified the templates for 3-D render view and use a high-resolution template. It also includes a few scalp view. You may pick up your favorite display for your paper (or presentation). Please go to the download page to download.
