Sleeping Noises

Who doesn't want to improve their memory and quality of sleep?

I just read an interesting article about improving sleep and memory.  It seems that introducing clicking noises while a person is in deep sleep, seems to show a significant increase in enhancing a person's memory.

The noises must be in sync with your brain so I guess the next big thing will be inventing headphones that "Click" while you sleep.  We will have a new generation of headphone clicking Einsteins.  But I hafta ask, how do these scientist come up with this stuff to try.  What was the motivation, a college prank?
