Figure 13: A: Simulated responses to the 5-ms-interval pulse train. Simulation was made on the 4-receptor version model (1) or full version model (2). Relative input magnitude was superimposed onto the membrane potential (as blue trace) for ease of comparison between timings of the input and discharges. B: PSTH of discharges in vivo that were evoked by the 5-ms-interval pulse train.
