Figure 12: A: Simulated responses to the 15-ms-interval pulse train. Simulation was made on the 4-receptor version model (1) or full version model (2); the latter differs from the former in that thalamocortical synaptic connections are endowed with short-term plasticity (depicted as decline of input magnitude). B: PSTH of discharges in vivo that were evoked by the 15-ms-interval pulse train.
