(a) Membrane action potential (dashed) of a sensory axon [14] and its temporal derivative (solid). For each trace an individual scale was applied on the ordinate. Time basis was chosen such that the potential maximum is at . (b) Normalized absolute amplitude of the frequency spectrum of the action potential derivative in a double logarithmic plot. The maximum was observed at 1.83 kHz. The amplitude converged to zero for low and high frequencies.
