Neuropsychology is a branch of psychology that focuses on the structure and function of the brain as they relate to specific psychological processes and behaviours. This field of psychology aims to understand how behavior and cognition are influenced by brain functioning and is concerned with the diagnosis and treatment of behavioral and cognitive effects of neurological disorders.

In this way, neuropsychology is similar to other fields of psychology and to psychiatry. However, unlike the other fields of psychology, the work in neuropsychology is almost always done in a laboratory environment, with the use of various animals. This is because of the way in which the human brain is studied: by monitoring the electrical activity of individual cells (or groups of cells) in the brain. This field of psychology is known as neuropsychology.

The field of neuropsychology has been expanding for many years and is now a widely used tool in the treatment of various neurological disorders.
