The short answer is deep brain stimulation (DBS), a targeted form of electrotherapy used to treat brain disorders like Parkinson's disease and OCD. The long answer, i.e. why DBS is sometimes so remarkably effective, remains poorly understood – but researchers this week took a big step on their path to…
Studies show that mild electrical currents can accelerate a number of cognitive functions, such as learning and math. But researchers now say there are mental tradeoffs to doing so.
After just five days of non-invasive brain stimulation and a bit of cognitive training, researchers at Oxford University were able to enhance people's high-level abilities, such as mental arithmetic and manual calculations. And remarkably, the effect lasts for months.
Slate writer Will Oremus has put together a fairly revealing article about how easy it’s becoming to supercharge our brains, prompting him to wonder why there’s still so much push-back against the idea of technologically enhancing ourselves.
