[Eeglablist] An issue with preprocessing procedure

[Lihan Wang]

Dear All,

 

     I've been trying to make ERD/ERS calculations of  some preprocessed EEG
data. However, preprocessing has been strictly implemented according to
standard ERP preprocessing procedure, which includes baseline correction and
re-reference. 

     After reviewing the literatures applying ERP analysis and ERD/ERS
analysis separately, I've found out that baseline correction and
re-reference procedures, which are always specified in analysis sections of
ERP researches,  are rarely referred in the ERD/ERS research. 

     I'm wondering whether standard ERP preprocessing procedure is working
well with EEG analysis? Especially, whether the baseline procedure which has
changed EEG amplitude of each epoch/trial will have an influence on ERD/ERS
calculation.

 

Thanks

Best regards

 

Selina Wang
