M37.4 CONNECT THE MECHANISM
Follow voltage, leakage, threshold, and reset
A leaky bucket that empties itself with a click every time it overflows. That's most of what a spiking neuron model does, and it explains why pressing harder makes a nerve fire faster, not louder.

Lesson overview
A leaky bucket that empties itself with a click every time it overflows. That's most of what a spiking neuron model does, and it explains why pressing harder makes a nerve fire faster, not louder.
What you’ll explore
- Leaky integrate-and-fire models accumulate input in a membrane state that decays, emits a spike at a threshold, and resets; rate and timing codes use different properties of spike trains.
