I am learning Nengo and was going through this simple tutorial.
It is basically a model with a single neuron trying to replicate the sine wave input.
My understanding is that the input is converted into the input current with the gain and the bias current of the ensemble, which then is used to generate the spikes. Then we connect the probe with the postsynaptic filter (or low pass filter) to measure the final output of the ensemble.
My question is that how Nengo determines the amplitude of the spikes before the synaptic filter? (i.e. The voltage of the spikes from the somma of the nueron before it reaches the neuro-transmitter). I guess there must be some kind of weights for this but I am not sure how to access them.
