Magnitude of detrended impedance signal at 4 kHz |Z _Detrend|_{4 kHz} of D. discoideum (3,750 cells mm⁻² added in Sorenseńs buffer) as shown in Figure 1 C. Cells were seeded at t = 0 min on a circular gold electrode ( = 250 µm). Boxes highlight magnification of the impedance signal. Data were smoothed by subtracting a moving average algorithm (box size: 800 points) to remove long-term trends.
