Electrophysiology Of The Neuron (2027)

A neuron at rest is like a charged battery. It maintains a , typically around

: The voltage briefly dips below the resting level before stabilizing. Electrophysiology of the Neuron

: 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. A neuron at rest is like a charged battery

. This negative charge inside the cell is created by an imbalance of ions—specifically sodium ( Na+cap N a raised to the positive power ) and potassium ( K+cap K raised to the positive power )—regulated by specialized pumps and channels. The Action Potential: The "All-or-Nothing" Signal making it more positive.

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