Figure 10: A: Simulated responses to the 160-ms-interval pulse train. All were based on the 4-receptorversion model with the exception that the conductance of GABAB-receptor ( g GABAB) was reduced by a factor of 0.1 (-2) or the conductance of the NMDA-receptor ( g NMDA) was reduced by a factor of 0.3 (-3). B: PSTH of discharges in vivo that were evoked by the 160-ms-interval pulse train.
