Neuroscientist Studies Ex-Grateful Dead Drummer’s Brain

SAN FRANCISCO (September 9, 2013)--Former Grateful Dead drummer Mickey Hart is sporting some sophisticated headwear when he’s on stage during his latest tour.

The cap is fitted with electrodes that capture his brain activity and direct the movements of a light show while he's jamming on stage.

The sensor-studded headwear is an outgrowth of collaboration between Hart, a Sonoma County resident who turns 70 on Wednesday, and a University of California, San Francisco neuroscientist who studies cognitive decline and prevention.

Hart has been interested in the subject since the late 1980s, when he watched his grandmother grapple with Alzheimer's disease.

He has invested time and money exploring the therapeutic potential of rhythm.

He wore the electroencephalogram cap while making his new album, "Superorganism," and tried to capture the feedback it gave him in sound.
