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.

Thank you, Alex. It is fixed.
Xu, Can the method shown in “Speeded…” apply to event related and/or randomized tasks? Thanks.
@Matthew
In principle yes, although the accuracy will drop if the signal amplitude is smaller.
