[Eeglablist] Using ICA to remove skin potentials?

[Stephen Politzer-Ahles]

Hello,

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.

Thank you,
Steve Politzer-Ahles
