An online course, “The Addicted Brain” offered by Coursera in collaboration with Emory University is starting in the month of June. This course is all about addiction to drugs and other behaviors. It also describes what happens in the brain and how this information will help in overcoming addictions.

The course will cover several aspects of addiction such as drugs, internet, gambling and other behaviors. Questions that will be addressed include:
-What is addiction?
-How do we study it and what have we learned?
-What makes a drug or activity addicting and what are its problems and toxicities?
-What happens in the brain when someone becomes addicted?
-Who can be an addict, and what are the vulnerability and risk factors?
-How do we treat addicts?
-How does government policy affect addicts?
-A current book will be recommended and various websites will be referred to so that the students can find reliable up-to-date information in the future.
