The spike trains for various RMS amplitude of the stochastic biphasic pulse trains. Noise (red traces) added to a subthreshold signal (black traces) and the spike trains (raster above each trace). From top to bottom: the RMS amplitudes of noise are 6, 18, 30 μA and a w , b w and b T are fixed at 0.01, 0.1 and 0.45. The power norm C 1 that correspond to each stimulus are 0.11, 0.53, 0.13 respectively
