Histograms of waiting time \(t_{{{\text{wait}}}}\) obtained under input conditions of \(V_{1}\) (a) 200, (b) 300, and (c) 400 mV with \(V_{1} = 80\) mV. Mean and standard deviation (S.D.) of \(t_{{{\text{wait}}}}\) are also shown. Dotted red lines are fitting curves using Eq. (1). Bin sizes were (a) 4.2, (b) 2.1, and (c) 1.3 ns.
