It might be scanner artifact if it aligns with slice acquisition.

Subject: ICA interpretation
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
