Description The local variable time-step method utilizes separate variable step integrators for individual neurons in the network. It is most suitable for medium size networks in which average synaptic input intervals to a single cell are much greater than a fixed step dt. "Independent variable timestep integration of individual neurons for network simulations" is a methods paper which demonstrates that the local variable step method has better performance than the fixed step method for networks in which only a few cells are active at a time.

The files reproduce fig 1 and 3 and provide a test framework for observing performance for the worst case Wang and Buzsaki model and the best case Ring model.
