Simulations demonstrate converging accuracy for the quasi-active versus reduced system. We used the neuron of Figure 2B with the nonuniform channel model of Table 3. The discretized neuron had 1121 compartments, leading to a 6726-dimensional system. For each reduced system size k, we performed 10 simulations of 50 ms each with 35 random alpha-function synaptic inputs for which ĝ _bs ∈ [0, 2].
