This chapter discusses the brain and its functions, and how and why the “malfunctioning” of the brain can lead to schizophrenia. The brain is a complex organ that regulates a multitude of functions inside the body as part of the nervous system. In order for the entire nervous system to work properly, it needs the help of “neurotransmitters” to communicate signals from the body to the brain in order to determine how the body must respond to outside stimuli. It is in these neurotransmitters where the symptoms of schizophrenia usually develop—with dopamine and glutamate being the usual suspects. Too much of these neurotransmitters can send the wrong messages to the brain, leading a person to think and act in ways they normally wouldn’t otherwise.

Keywords:   brain, schizophrenia, nervous system, neurotransmitters, dopamine, glutamate
