Electrophysiology Of The Neuron Here

: Sodium channels close and potassium channels open, allowing K+cap K raised to the positive power to exit and bringing the voltage back down.

When a neuron receives enough stimulation, it reaches a critical "threshold" (around Electrophysiology of the Neuron

). This triggers an , a rapid spike in electrical activity that travels down the axon. : Sodium channels close and potassium channels open,
