Neurons

Neurons are specialized cells that transmit chemical and electrical signals to facilitate communication between the brain and the body.

Neural impulses occur when a stimulus depolarizes a cell membrane, prompting an action potential which sends an "all or nothing" signal.

The synapse is the site at which a chemical or electrical exchange occurs between the presynaptic and postsynaptic cells.

Neurotransmitters are chemicals that transmit signals from a neuron across a synapse to a target cell.

Neural networks consist of a series of interconnected neurons, and serve as the interface for neurons to communicate with each other.
