Fig. 6.

Postural tremor detection across subjects. A. Postural tremor was differentiated from rest by increased tremor frequency and double tremor frequency activities (indicated by the arrows) in the EMG; B. Postural tremor was associated with increased tremor frequency activities in the thalamic LFPs (indicated by the arrows). C. ROC curves of tremor detection based on thalamic LFPs (individual sides in thin blue lines and average across all sides in black). D. AUC, Sensitivity and false positive rates. Thick horizontal lines show the mean values and x show data from each individual test session. E. Activities between 4 and 7 Hz contributed most to the tremor decoding, with feature labelling the same as in Fig. 3.
