You also need to look at the time course to decide whether it's an artifact or not.

Hi all,
I am doing a MELODIC analysis on 88 subjects with a high pass filter 100s and low pass filter 2.5s. Some of the components tend show a wispy pattern, with alternating activation/deactivation, as shown in the attachment. Does anyone have experience with interpreting this kind of activation? I thought it might be related to pulsation
artefacts?
Thanks, Jasper
