Definition

Electrical charge refers to the movement of electrically charged particles, such as ions, along a neuron. It is responsible for transmitting signals and information throughout the nervous system.

Related terms

Ion Channels: These are protein channels that allow ions to flow in and out of neurons, regulating the electrical charge.

Action Potential:

An action potential is a sudden change in electrical voltage that occurs when a neuron fires. It allows for the transmission of signals between neurons.

Resting Potential:

Resting potential refers to the stable, negative charge inside a neuron when it is not firing. It represents its resting state before receiving any incoming signals.
