[Eeglablist] A question on ERS / ERD

[Marco Montalto]

Dear List,

Does anyone know whether the power values obtained in EEGLAB that by default are scaled to log(dB) i.e. (10*log(microvolt^2)), are usable for computing ERS / ERD using the method of Pfurtscheller, which is: (A - R) / R X 100 (where A is the power in the frequency band of interest in the period after the event and R is the power in the preceding baseline or reference period)?

Thanks and regards,
Marco
