Studying the effects of naturally occurring chemicals in the brain, drugs and therapy on our behavior, researchers are equipping the medical profession with a better understanding of the chemical processes of the brain and assessing whether it’s possible to manipulate them to treat addiction and mental illness.

Attempting to understand a mental illness or addiction and ameliorate its effects often starts with brain chemistry. Magnetic resonance imaging (MRI), positron emission tomography (PET), and simple observation of humans and animals let researchers better understand why, for instance, a person might be more susceptible to becoming a heavy smoker (that is, more likely to become addicted to nicotine).
