TED Talk: Andres Lozano on Parkinson’s, Depression and the Switch That Might Turn Them Off

During a TED Talk, Andres Lozano, chair of the University of Toronto’s Department of Neurosurgery, shares the fascinating ways in which deep brain stimulation can correct the effects of Parkinson’s and Alzheimer’s disease. From the video’s description: 

“Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down — like a radio dial or thermostat — to correct dysfunction. Andres Lozano offers a dramatic look at emerging techniques, in which a woman with Parkinson’s instantly stops shaking and brain areas eroded by Alzheimer’s are brought back to life.”
