Definitions:

Action Potential

A rapid rise and subsequent fall in membrane potential across a cellular membrane, crucial for the propagation of electrical signals in nerve and muscle cells.

Local Potentials

Electrical changes in neurons that are confined to a small region, serving as the initial response to stimuli, potentially leading to action potentials.

Membrane Potential

The voltage difference across a cell's plasma membrane due to the differential distribution of ions.

Hyperpolarized

Hyperpolarized refers to a state where a cell's membrane potential is more negative than its normal resting potential, often making the cell less active.
