Computational efficiency of some standard single-neuron models.

The ts to FP column is the number of time steps taken to approach the FP with a tolerance of 10−8. The ms/ts column shows the proposed scale factors for the time step of each model, assuming a spikes takes about 1 ms. The number of FLOPs for the conductance based model is estimated assuming a 4th order Runge-Kutta ODE solver with step 0.001 ms. Each model’s average CPU cycles has been performed over 5,000 realizations of 3,000 ms considering the lowest conversion factor in the table for the considered model.
