Dear all,
Is it correct that until now the physiological monitoring data is not
made use of in the preprocessing of the rfMRI data? I would like to
correct for cardiac and respiratory signals and wondered how to best do
that. I can see that FIX-denoising probably takes care of this type of
noise but I am particularly interested in looking at the brain stem and
in my experience, including physiological regressors in the
preprocessing makes a big difference there.
Would you recommend using the spatially (minimally) pre-processed rfMRI
data, performing the high-pass filtering on it myself and then
incorporating the physiological regressors at that stage, or is there a
better stage at which to do it? Also, is there a standard procedure for
regressing out the physiological regressors that you can recommend?
Many thanks in advance!
Kind regards,
Miriam
