Scientists say they have figured out how an experimental drug called ketamine is able to relieve major depression in hours instead of weeks.

Researchers from Yale and the National Institute of Mental Health say ketamine seems to cause a burst of new connections to form between nerve cells in parts of the brain involved in emotion and mood.
