[Eeglablist] ICA for muscle artefacts from overt responses?

[Wout Duthoo]

Hi,

 

I ran an EEG experiment in which vocal responses were recorded, so that
strong muscle artefacts are visible in the EEG signal.  

 

In general: is it a good idea to run an ICA, identify components related to
these muscle artefacts and then correct for these (in addition to correcting
for eye blinks)? Or would it be better not to correct for these motor
artefacts, given that they will probably average out when calculating the
grand average?

 

Thanks in advance!

 

Wout
