A neuron at rest is like a charged battery. It maintains a , typically around
: Voltage-gated sodium channels snap open, allowing Na+cap N a raised to the positive power to flood into the cell, making it more positive. Electrophysiology of the Neuron
). This triggers an , a rapid spike in electrical activity that travels down the axon. A neuron at rest is like a charged battery
: The voltage briefly dips below the resting level before stabilizing. Electrophysiology of the Neuron
: Sodium channels close and potassium channels open, allowing K+cap K raised to the positive power to exit and bringing the voltage back down.
