Incredible stories that had to be shared.

You're about to witness a miracle, revealing a secret locked away in our brains. Astonishing surgery that's transformed lives forever, changed human wrecks into happy human beings. They call it deep brain stimulation and it really has to be seen to be believed. It's an intricate operation, performed while the patient is actually conscious, guiding the surgeon on his way. Breathtaking stuff that's already been successful for patients with Parkinson's disease, Tourette's Syndrome and even depression.
