[Eeglablist] whether or not subtracting baseline while calulating coherence

[wu xiang]

hi all:

I wonder about that whether or not the baseline coherence should be
subtracted while calulating coherence.

For baseline may be different in different conditions and subjects, it
was subtracted during ERP analysis. Also, the spectra-power of baseline
was subtracted while calculating spectra-power, such as the
baseline-nomalized ERSP in EEGLAB. However, why the coherence of
baseline was not subtracted in most papers (I can not find a paper where
the coherence of baseline was subtracted)?

Would someone recommend some papers where the coherence of baseline was
subtracted to me for reference? (It's important to me)

Thanks very much
