Time series of electrode impedance measurements in (a) Monkey C and (b) Monkey B. The black lines represent the mean impedance across all functional electrodes, and the grey shaded area indicates the confidence intervals (CIs). The vertical red dashed lines indicate the days on which functional mapping was performed. Both animals maintained stable impedance values throughout the recording period, suggesting reliable long-term electrode‒tissue contact.
