Description

While working through the tutorial, I tried to run the cell where the snn.Synatic LIF Neuron is used. The cell itself works, but the plot shows, that the Neuron isn't doing, what it should do. The reset_mechanism needs to be set to "zero" and the threshold needs to be lowered, that the LIF Neuron at least uses any reset. With the default, the reset isn't working at all and the neuron just fires every timestep. Also the current isn't decaying over time.

In the following picture is visible what I mean.
lif1 = snn.Synaptic(alpha=alpha, beta=beta)

lif1 = snn.Synaptic(alpha=alpha, beta=beta, reset_mechanism="zero")
