Interval discrimination with different levels of noise. Each plot shows the response of five outputs units, after training each output unit to one of five target intervals: 50, 100, 150, 200, and 250 msec (dashed lines). Novel stimuli representing intervals from 25 to 300 msec were used to test interval discrimination and generalization. Simulations were performed with three different levels of noise injected continuously into all the Ex and Inh units of the network. The rms of the voltage of the Ex unit wasA, 0 mV; B, 1.4 mV; and C,4 mV.
