A fundamental property of matter that leads to electromagnetic force between objects. The charge can be positive or negative and is measured in coulombs.

Electrons

Negatively charged subatomic particles that orbit the nucleus of an atom.

Microelectrodes

Small electrodes used to record electrical activity or deliver electrical stimulation in biological tissue.

Giant Axons

Unusually large nerve fibers that facilitate rapid transmission of electrical impulses, especially notable in specific animal species.
