Single-frequency impedance measurements recorded for NHP2’s DBS electrodes, including the rejuvenated channels (dark markers) and adjacent unrejuvenated channels within each segmented ring (open markers), showing the changes in post-rejuvenation impedance over 11days. Impedance change is depicted as a difference between the pre-rejuvenation value measured at 1 kHz and each subsequent value. Note that both DBS leads showed lowered impedance lasting approximately 4 days, followed by a return to impedance values exceeding the original measurement.
