Figure 2.
A, B, Time–frequency plot of the power spectrum for the EMG (A) and the LFP recording (B). C, wSNR of the EMG over time for the tremor frequency band is shown (as per Eq. 9). The red line depicts the 95% confidence interval, which at the same time is the threshold for tremor activity. Below, tremor activity is represented as binary data. D, WCS for the EMG and the LFP recordings.
