How it works
Apply an input current injection to the LIF neuron using switches.
This gets added to a membrane potential which is decayed over time. If the membrane potential exceeds the threshold then trigger a spike.
How to test
After reset, the membrane potential will be set to 0.
Then change the inputs to change the current. A higher current should trigger a higher firing rate.
