fMRI Tips, Tutorials, Code, Examples
Previously I said I was developing a ROI analysis program (https://www.alivelearn.net/?p=1421). Here it is: Download main program (beta version) at https://www.alivelearn.net/xjview/xjviewpro/xjviewpro.p Download sample input excel file: https://www.
Quite often you need to convert the coordinates of some voxels in MNI space to regular matrix coordinates. Below is a script to do so: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% mni2cor %%%%%%%%%%%%%%%
This is a manuscript Chao and myself prepared for a “commentary”. We think NIRS based hyperscanning has a great potential on the shift from one-person neuroscience to 2-people neuroscience. —- Toward an Ecologically Valid Second-per
The vast majority of studies on the relationship between human brain and behavior try to answer the “where” question: Where in the brain are the regions that are responsible for a particular task? For example, where is the finger movement
Both are on NIRS (Near Infrared Spectroscopy). The first one is on how to detect NIRS activity earlier using multivariate (SVM) method; the 2nd one is a comprehensive comparison between NIRS and fMRI. Cui, Bray, Reiss (2010) Speeded Near Infrared Spe
I saw at least two web pages saying that the reference slice can be chosen during slice timing correction. For example, http://www.fil.ion.ucl.ac.uk/spm/doc/manual/spatial.htm. I disagree. Let’s take the first volume as example. Assume TR=2 and

Both E-prime and MatLab are popular tools for presenting stimuli for fMRI, NIRS and behavioral experiments. Here are a comparison between them. E-Prime MatLab + psychophysics toolbox price ~$1000 MatLab cost, $50-500 easy to use easy moderate need co
