About the Course

What happens in the body when a person smokes a cigarette? After several weeks of smoking? When a person takes antidepressant or antipsychotic medication? A drug for pain, migraine, or epilepsy? A recreational drug? Neuroscientists are beginning to understand these processes. You’ll learn how drugs enter the brain, how they act on receptors and ion channels, and how “molecular relay races” lead to changes in nerve cells and neural circuits that far outlast the drugs themselves. “Drugs and the Brain” also describes how scientists are gathering the knowledge required for the next steps in preventing or alleviating Parkinson’s, Alzheimer’s, schizophrenia, and drug abuse.

Recommended Background

Neuroscience, the most interdisciplinary science of the 21st century, receives inputs from many other fields of science, medicine, clinical practice, and technology. Previous exposure to one or more of the subjects listed in "Suggested Readings" will provide a good vantage point, as we introduce material from these subjects.

Suggested Readings

We recommend (but do not require) that students read Molecular Neuropharmacology: A Foundation for Clinical Neuroscience (Second Edition)
by Eric Nestler, Steven Hyman, and Robert Malenka.

The instructors and students provide additional appropriate links to reading on molecular biology, genomics, physiology, pharmacology, cell biology, biophysics, organic chemistry, psychiatry, neurology, and electrical circuits.

Course Format

The class consists of lecture videos, 8 - 15 minutes in length. These contain 2-3 integrated quiz questions per video. There are standalone quizzes each week.  Total lecture time is ~ 14 hours.


  • How does "drugs and the Brain 2014" compare with the 2012-13 version?
Compared with the 2012-13 version, the 2014 version of Drugs and the Brain has two additional weeks of material, covering pharmacokinetics, opioid addiction, drugs for migraine, epilepsy, and anxiety.

  • Will I learn enough to prescribe / advise / diagnose / change my friends’ medication? My own medication?
The instructor is not an MD and cannot prescribe. Don’t change any medication you now receive as a result of this course.

  • Statements of Accomplishment?
The instructor and Coursera will issue such a statement.
