Extended Data Fig. 2: Noise and gain characterization across banks and recording sites.
From: Large-scale high-density brain-wide neural recording in nonhuman primates

a, Distribution of measured noise (mean +/− SD) for 384 recording channels across probe banks 0-11. b, Correlation of noise measured on the same readout channel for all recording channels recording from bank 3 (abscissa) and bank 7 (ordinate). Correlation between all pairs of banks is similar. c, Distribution of difference of noise recorded from one readout site and other sites that can be connected to the same readout channel. For the probe tested, a total of three sites had measured noise > channel mean + 2 uV. d, Measured peak-to-peak amplitude of a 1 mV, 3 kHz sine wave (mean +/− SD) as a function of position along the probe. Additional methodological details provided in the Materials and Methods Summary.
