Before revision: We design a high efficient exponential time differencing method (ETD) for simulating pulse-coupled Hodgkin-Huxley (HH) neuronal networks. The ETD method is attractive because it can solve the stiff problem when a HH neuron fires a spike and allows a large time step to raise efficiency .
After revision: We design a high efficient exponential time differencing method (ETD) method allows using a large time step to raise efficiency .
