D) the role of genetics in controlling behavior.

Positron-Emission Tomography

An imaging technique that uses radioactive substances to visualize and measure changes in metabolic processes, and hence, the functioning of organs and tissues.

Brain Activation

The process by which regions of the brain become more active, typically in response to a specific stimulus or task.

Genetics

The biological study of genes, heredity, and the variation of organisms, determining characteristics of living organisms.
