Hi, Clément-
Re. #1: Oh, right. If I could keep my attention span longer than 5s (or 5ms?), I would have remembered tha-- oh, look, a squirrel!
Re. #3: Hmm, that is interesting about your mALFF experience. I wonder if using "scale" during the lemur processing would have done something similar there, so that something like ALFF might have been more meaningful? I am not certain.
I don't know that you there is necessarily a connection between high mALFF and higher neuronal activity. Since the BOLD signal is a secondary response to neuronal activity, as well as being heavily composed of other factors such as vasculature and blood flow -- with a potential sprinkling of artificial stuff like subject motion, EPI distortion and scanner artifacts -- I think it would be hard to assume that kind of relationship between the two things. That would require some detailed study on its own.
