How do you create a neural model in Nengo?

I am trying to simulate a network of GLM neurons in Nengo and it seems that this is not an available neural model in Nengo. I tried to search how I could implement a neural model in Nengo however, I came up empty handed. Instead, I found this paper on how to do it for plasticity rules:

Would anyone be able to guide me as to how do this for a neural model? Can I extend a Nengo interface and override functions to implement a neural model? If not, is there any alternatives?

You can find an example here showing how to implement a new neuron model in Nengo:
