These are life is like read everything about it -- rhythm I mean I am aware of and so you Mickey Hart is best known for the rhythms he created with the grateful death. But lately he's more concerned with a different kind of with -- -- them in the brain pointing out what to. Through them central sounds like you. It's the master clock it makes everything go in his years on the road Hart says he always felt music and a special power over the brain to heal in the wake of its. But one -- that hunch became a certainty my grandmother had alzheimer's advanced alzheimer's and she couldn't speak -- spoken in over a year.

Being generated by the neurons and -- this is a live image of Mickey -- brain he's taking this year on tour with him -- live audiences can watch -- neurons Paul says he plays the drums.

By finding out what the -- are in the brain we'll be able to find out how to use music is medicine it all started by accident Hart was asked to do was speaking engagement. UCSF neuroscience professor Adam -- all -- His only with studying how to retrain the brain using video game technology. But using that technology to look at the brain that was an entirely new light this concept has -- make -- therapeutic has been around for a long time. This just really no studies that have carefully controlled. -- -- rhythmic experience and look for changes in the brain and only now our computers powerful enough to show those changes lives live recording right now from its brand now Mickey Hart is the first subject. In a new experiment seeing his own brain waves as he drums he tries to control the rhythm of his brain by changing the rhythm of the music I move into its time. And I find where -- it's doing and go with yet. And I try to win train with and stay there as long as possible and then move it slightly. In return it to the right turn into -- Hart says it's a dance one doctor is Ollie says could hold great promise for patients whose brains have lost their natural rhythm but we can help. Re organize those -- -- train that. And hopefully we can improve cognition along with that a -- of sorts with huge medicinal promised that for heart is also recreational -- to get you high.
