A method is provided for determining a threshold (81, 82) for spike (12) detection in an electrophysiological signal (11). The method comprises a step of determining an estimated envelope (31) of the electrophysiological signal (11), a step of, based on the estimated envelope (31), determining an estimated Gaussian noise, a step of determining a distribution (51) of instantaneous amplitudes of the estimated Gaussian noise, a step of determining a mode (61) of the distribution (51) of instantaneous amplitudes, and determining the threshold (81, 82) based on the mode (61) of the distribution (51) of instantaneous amplitudes.
