Fig 1. Spectral profiles (average) during resting, upright standing, and gait.

Fig 1

Average spectral power of the STN local field potential during resting (blue line), standing (pink line) and gait (green line) for the two hemispheres, with less (–) and more (+) striatal dopamine innervation. Results are corrected for the nominal noise floor level of the device (150nV/rtHz, [32,33]), all values above 0dB/Hz are reliable. Shaded areas represent the confidence intervals (5–95%) of the group mean. The peak at 32 Hz is a known artefact of the Activa PC+S® system tied to clock settings or due to a triggered check of the battery status.
