In this episode of A New Prescription, Dr. Leonard and Andrew Zwelling talk with Duke professor Dr. Cameron McIntyre about deep brain stimulation (DBS) — how it works, its success in treating conditions like Parkinson’s, epilepsy, and OCD, and new research into depression and PTSD. They also explore the future of brain-machine interfaces, the ethics of neural enhancement, and what this technology could mean for human health and free will.
