I would like to ask something about ICA artifact cleaning:
is there an ideal number of ICA components for removing artifacts? I mean, not every artifact inside an EEG file comes from the eyes, there are some artifacts due muscular and movement contribution, so I guess ICA is also suitable for removing them,
But I guess if I remove a lot of ICA components the final signal will be weird and maybe artificial,
so is there a theoretically correct way to choose which ICA selectors shoul be removed without distort original signal or creating a false signal?
Thanks in advance!
