How it works
Apply an input current to the LIF neurons through the switches.
This will add to the membrane potential that decays over time. If the membrane potential exceeds the threshold, then a spike is triggered.
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.
