Mickey Hart monitored… for science!
From ABC News
The rhythm of Hart’s drum isn’t the same as the rhythm of his brain, but there is a connection between the two… different sections of the brain activate and deactivate at the same time, resulting in a rhythmic pulse of activity throughout a brain region.
But when we age, that rhythm starts to shift. “The rhythmic connection between different brain areas can change, or the frequency of the rhythm itself could change.”
