[Eeglablist] ICA for muscle artefacts from overt responses?

[Stephen Politzer-Ahles]

Hi Wout,

I'm not an expert on this topic, but I have seen something like this done
before. See, e.g., experiment 2 of Riès et al. (2011) in *Journal of
Cognitive Neuroscience*<http://www.mitpressjournals.org/doi/abs/10.1162/jocn.2010.21467>,
which uses a blind source separation algorithm. Maybe others on the list
with more experience on this might know more about it.

Best,
Steve
