The Reward System—Drugs
Lecture no. 25 from the course: Understanding the Brain
Taught by Professor Jeanette Norden | 31 min | Categories: The Great Courses Plus Online Science Course
Psychoactive drugs that produce euphoria or a "high" do so by altering the biochemistry of the endogenous reward system. Such drugs can be both physiologically and psychologically addicting. Using cocaine and marijuana as examples, we investigate how drugs can hijack this system and even produce permanent changes in the brain.
