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.

Cell Membrane

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment, controlling the movement of substances in and out of cells.
