Washington State University helped confirm that brain activity links to sleep. They have never known how till now. They have Findley figured out how it is linked to the brain. It is just a cascade of chemical transmitters and proteins which causes you to sleep. This says you you have to go to sleep if your brain tells you to.

I think this is very helpful to us to control sleep disorders. 50 to 70 million Americans in this country have sleep disorders. This can help the US to make a medicine to protect against sleep disorders and even mishaps where sleep involved car crashes happen. Motor vehicle drivers pay a total of $48 billion a year for sleep involved car crashes. This is a great accomplishment for the US to find this out, this invention could help pull the US economy back to order.
