Simulation of interval discrimination with altered time-dependent properties. In these simulations the target intervals were 50, 100, 200, 300, and 400 msec (dashed lines).A, Control results with the same parameters used in Figure 6. B, Flattened slow IPSPs and PPD. In these simulations GABAB-dependent properties were flat 20 msec after activation, whereas PPF of EPSPs remained normal.C, Flattened PPF. D, No PPF and no GABAB-dependent properties.
