+**Appunti**:
+
+The reason the pump isn't the "timer" for the refractory period is scale.
+
+A single action potential only changes the internal sodium concentration by a fraction of 1% (approx. 0.0001 mM).
+
+The neuron does not need to "pump out" that sodium to fire again. It has enough "buffer" to fire hundreds or even thousands of times before the internal sodium concentration becomes a problem.
+
+Peer Correction: If the neuron had to wait for the pump to reset the concentration before every spike, our brains would run at about 1 Hz (1 spike per second) instead of 100–500 Hz. The pump is the "slow recharger," not the "instant reset."
