Nuisance Regressors WM, CSF, Global Signal in gPPI Analysis?

1

Hi everyone,

I know that there is a debate around using global signal regressors in resting-state connectivity analysis. But how about using those in GLMs used for task-based (g)PPI analyses? I can’t seem to find any information on that.

Thanks for your input!

I, too, am interested in peoples’ thoughts about this! So I’m hoping, almost a year later, that someone will be thinking about this…
