Brain Music: Putting the Brain's Soundtrack to Work

http://www.sciencedaily.com/releases/2009/04/090424114646.htm

This article discusses the fact that brain waves can be "recorded" as musical notes and played back to the person, causing them to relax or become more focused. The music that is recorded is different for each persons brain. The compositions can be especially useful for first response federal agents, police, and fire fighters to combat the stress that inherently comes with their jobs. A group of first response fire fighters will be the first group to be tested as part of this project. If the project is a success we may soon see this become mainstream, which would help people be more productive at work and help people who have trouble sleeping or have jobs that require varying sleep patterns.
