Effects of posture maintenance and movement on LFP PSD amplitude. LFP recorded in P6 from a montage including a contact used for chronic stimulation (TC) on the right side. High-beta-LFP (arrow, 23Hz) PSD amplitude decreased during posture/action (red line) comparing to the rest condition (black line). Horizontal black bars on the x axis correspond to a statistical difference with p = 0.0001. PSD power spectrum density. LFP recorded 3 and 12 months after surgery were pooled for this analysis.
