ABSTRACT
Behavior, including pathological behavior, has its origins in brain functioning. Many of our current treatments for pathological behavior are biological in nature; for example, we use drugs that alter neurotransmitter systems. Increasingly, noninvasive imaging techniques are used to study and diagnose brain abnormalities associated with some forms of psychopathology. Understanding psychopathology must ultimately include an understanding of its biological bases. Th is chapter will introduce some issues that are important in understanding the biology of psychopathology.
