The analysis of Burst activity is calculated in several steps. First, the second derivative of the power in 9 frequency bands was calculated. In this time series, peaks in power are defined by the points in time in which the value of the second derivative turns from positive to negative. After the peak power detection, bursts were identified by the evaluation of two criteria. The first criterion evaluates the duration of the full-width half-maximum (FWHM) around a peak in the power within a frequency band of interest. When the FWHM is larger than 2* and smaller than 10* the average cycle duration of the center frequency within a frequency band of interest, the first criterion is met. The second criterion evaluates the difference between the power at the start of the burst period and the peak power of the burst period. When this
difference exceeds the median band power + 1* the standard deviation, the second criterion is met.
