It stings a little every time I hear a story like this on the BBC about the revolutionary new invention being an implanted device to stimulate parts of the brain. This is like the third time. They treat it like it has never been done before, but in truth, it's something that has been done for decades for Parkinson's, epilepsy, and a handful of other conditions with increasingly precise targeting and triggers. Got one for my epilepsy two years ago. It reads my brain waves and sends a targeted stimulation deep in my brain to stop the seizure before it spreads.
