Before revision:  The model is able to simulate the summation of presynaptic action potentials in qualitative agreement with biological neurons. We also explore the response of postsynaptic neurons  to two well known noise driven processes: stochastic and coherence resonance.
After revision:  The model is able to simulate the summation of excitatory inputs from synapses and illustrate its use by characterizing some functional properties of postsynaptic neurons. In this regard, we study the response of postsynaptic neurons to two well known noise driven processes: stochastic and coherence resonance.
