Projection of a NIRS channel on a brain surface

When analyzing the data in our concurrent NIRS-fMRI study, we are particularly interested in how the NIRS signals were correlated to the fMRI signal. To answer the question we need to create an ROI (region of interest) in brain which is directly unde
