Axons
When an electrical impulse takes a trip down a nerve cell's axon, it releases a tiny chemical messenger called a neurotransmitter.

They might assist reduce a few of the devastating symptoms related to schizophrenia, such as hearing voices, hallucinations and not logical thinking, and being dubious of others.
They do this by blocking the dopamine receptors on nerve cells-- think of 2 populations of mind cells expressing locks, one with D1 and the other with D2 receptors-- to make sure that the floating dopamine can not bind to these nerve cells and cause their activity. Rather, it gets reuptaken back right into the presynaptic vesicles and neutralised or ruined by a chemical called monoamine oxidase.
