Sodium channels are proteins in cell membranes that allow sodium ions to flow into or out of cells, playing vital roles in the generation and transmission of electrical signals in neurons and muscle cells.

Hyperpolarization

An increase in a cell's membrane potential, making the cell more negative and less likely to fire an action potential.

Voltage Fluctuations

Variations in the electrical potential difference that can affect the performance of electronic circuits and power systems.
