Example STN during the different stimulation sets.

<p><b>A</b>, <b>B</b>, <b>C</b>, and <b>D</b> are raw waveforms and spectrograms from the baseline epoch, 130 Hz/2V DBS epoch, 60 Hz/2V DBS epoch, and 130 Hz/1.35V DBS epoch, respectively. Spectrograms are displayed with 99% window overlap. <b>E</b>: Relative PSD traces of the four epochs. Black = baseline; red = 130 Hz/2V; blue = 60 Hz/2V; green = 130 Hz/1.35V. Colored dashed lines represent 95% confidence intervals for each spectrum.</p

Peak detection for all fourteen sides.

<p><b>A</b>—<b>N</b> are absolute PSDs from all fourteen recordings. Black = baseline; red = 60 Hz/2V; dashed = 130 Hz/2V. Arrows indicate where peaks were detected by the algorithm, and the color of an arrow corresponds to its PSD spectrum. Black asterisks on <b>J</b> (one for 60 Hz/2V) and <b>K</b> (two, one for 60 Hz/2V and one for baseline) indicate peaks chosen visually.</p

Change (Δ) in Mean Power with Respect to Baseline.

<p>The total power delivered during 60 Hz/2V DBS was equivalent to that delivered during 130 Hz/1.35V DBS. However, their effects on baseline spectral power were significantly different from each other in both the alpha (P < 0.001) and beta (P = 0.006) bands.</p><p>Change (Δ) in Mean Power with Respect to Baseline.</p
