Your school probably has science classes like biology and chemistry and maybe even ecology, but does it offer a class specifically on neuroscience?

Neuroscience is a branch of biology that focuses on the body’s nervous system—which includes the spinal cord, nerves, neurons (nerve cells) and, of course, the all-important brain.

Work in the neuroscience field is varied and exciting. Neuroscientists might study how messages travel from one area of the brain to the other, or they might focus on how the brain is involved in behavior and decision-making.

Still others might work to find causes of and cures for diseases and medical problems like stroke, Parkinson’s disease, depression, Alzheimer’s disease, schizophrenia, and addiction.

At NIDA, research focuses heavily on neuroscience, considering that drug addiction is a brain disease. Without neuroscientists and the research they do, we would be unaware of some pretty important things—like how the brain isn’t fully developed until a person is well into their 20s and how drugs like marijuana affect the teen brain differently than an adult brain.

So much about the brain is still unknown. That makes neuroscience a particularly exciting field. If you are interested in help shed light on the mysteries of the brain, consider exploring neuroscience as a career. Check out the advice NIDA scientists offered to SBB for teens interested in a future career in science.
