Hello,<br><br>I was wondering if anyone knows about (or could point me to references about) whether it's feasible and valid to use ICA to remove low-frequency artifact like skin potentials. I have a set of recordings that has lots of problems with these, and while I've found that a 0.5 Hz high-pass filter can attenuate them somewhat, I'm also aware that high-pass filtering can have some big consequences. In the past I have used ICA to remove EOG artifact and I know of others who have used it for things like alpha, heartbeat, and muscle-related artifacts, so I'm curious about whether I can use it to remove skin potentials and what kinds of distortions it might create. But before I do that I wanted to see if others use it for that, or if it sounds crazy.<br>
