Voltage-Sensitive Ion Channels

Voltage-sensitive ion channels are a class of transmembrane proteins that open or close in response to changes in the electrical potential across the cellular membrane, essential for neuronal signaling.

Action Potential

An action potential is a temporary reversal in the electrical charge across a cell's plasma membrane, responsible for the propagation of nerve impulses.

Optogenetics
