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.
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.
