[Eeglablist] acceptable electrode impedance

[장진원]

Dear all,

The guideline usually recommends to use <10k ohm for electrodes in eeg
study. As far as I know, this is important to preclude artifacts and
noise. But there are many published studies with >50k ohm.

Is it acceptable to use high-impedace electrodes if all signals look good
by an eye? Maybe these "good" signals might not mean real good
representations of cortical sources.

Best,
