Chronic recording stability. a, b, For an hour-long block of data background, the RMS of the time series from on the microwire in dorsal raphe (a) and one accelerometer channel (b) are computed over 5 s long overlapping windows (overlap = 1 s). c, The RMS background of the microwire channel remains flat with respect to the accelerometer activity during the hour. The maximal range of the background noise (∼7 µV) is much smaller than the amplitude of the action potentials recorded on that channel (c, right).
