Spike occurs in the presynaptic neuron (hence on_pre) it causes an The syntax on_pre='v_post += 0.2' means that when a In this case, the source and target are both the same, the That we are defining a synaptic model that goes from source to Next we define the synapses: Synapses(source, target. Prove this to yourself by commenting out the two lines that define the Synapses - it won’t spike at all (the driving current I is 0). I=0 and tau=100*ms which means that on its own - without the That is driven to repeatedly spike at a fairly high rate. Neuron 0 has I=2 and tau=10*ms which means Which has the same differential equation but different values for
