To quantify evoked power, single trial EEG epochs were averaged to create event-related potentials (ERPs). ERP data were subjected to the wavelet decomposition described above, and evoked power was calculated by squaring the output. The evoked power values were 10log10 transformed and then baseline corrected by subtracting the average of the pre-stimulus baseline (−100 to 0 ms) from each time point separately for every frequency. The resulting event-related change in evoked power values (relative to baseline) are in decibels (dB).
