Such cycles of integration and reset occurs naturally. We observe increasing frequency of reaching current threshold (fire) with increase in input V SG . Figure 5(b) shows output frequency vs. input V in = V SG akin to Fig. 2 (c). A threshold is observed such that |V in |...

but in vivo, additional large sources of variability will occur from stochastic transmission at synapses, complex dendritic integration, neuromodulation, etc. These mechanisms, which are necessary for exact integration of single-neuron models into systems models are beyond the scope of the current study...
