Dear experts,
i am conducting a functional connectivity analysis and would like some
advice on setting up my model and contrasting it. i have extracted time
series for my seed, the whole brain, a ventricular seed and a deep white
matter seed (splenium
of cc). if i want to examine the functional connectivity of my ROI after
removing the variance accounted for by the nuisance variables mentioned
above, do i just enter all of these as regressors into a multiple
regression equation and then contrast the ROI seed with 1 and leave the
others as zeros?
any help would be greatly appreciated,
nick bradfield
