In the absence of agreement that everyone should use the same simulator, a tool to make it easier to share models between groups was needed, and PyNN was born. Within FACETS, PyNN is being used for simulations of large-scale models of primary visual cortex and of generic cortical circuits with synaptic plasticity.
