SpikingNeuralNetworks is a really good start on this. The thing I found missing when I briefly played with it was easily composing networks. I have a heap of code that binds LightGraphs to a metadata structure that is more suitable for this sort of thing. It’s littered with notes and untested right now though. I was hoping to have something out weeks ago (nothing official but just to get some conversation going) but some events New York state have disrupted … everything.
Edit: by “more suitable for this sort of thing” I just mean composing networks not the actual neuron attributes that SpikingNeuralNetowrks does.
