Lesson 1 of 5

What is neuroscience?

The study of the nervous system — and the many fields it connects.

Neuroscience is the study of the nervous system — how we think, feel, move, learn, remember, sleep, sense the world, and respond to it. It connects many fields: biology, psychology, medicine, engineering, computer science, and education. There is no single path in.

What has your brain already done today?

Select one or more — you can pick several.

Zooming out: the levels neuroscience studies

Notice that the same question can be asked at six different scales — and that neuroscience needs all of them.

One Brain, Many Lenses

Neuroscientists often approach the same question from completely different directions. Select a field to see what it brings to the investigation.

How do genes influence the development of neurons?

Three Key Takeaways

  1. 1Neuroscience is the scientific study of the nervous system — the brain, spinal cord, and the networks of nerve cells throughout the body.
  2. 2The nervous system can be studied at many levels, from molecules and cells to whole behaviors and experiences, and each level answers different questions.
  3. 3Neuroscience connects many fields — biology, psychology, medicine, computer science, and more — so there are many paths into studying the brain.
