Chapter 3—The Brain and Behavior
... Neurons send messages by creating a brief wave of electrical charge; this charge is called an action potential. The action potential abides by the all-or-none principle. Each axon branches out into numerous fibers that store those chemicals called neurotransmitters. These are chemicals that are rele ...
