Chronic Electrode Performance. a-c) Signal yield of SU (a), significant evoked MU (b), and significant evoked LFP (c) over days (Blue: contralateral bone screw reference & Black dashed: common average reference). d-f) Signal quality of SU (d) SNAR, MU (e) SNFRR, and LFP (f) SNLPR over days. g-i) Signal strength of SU (g: amplitude), MU (h: amplitude), LFP (i: power). j-l) Signal Steadiness of SU SNAR of only active recording sites (j), 1 kHz impedance (k), and frequency shifts in the peak LFP power (l) over time.
