Students Zap Their Brains For a Boost, For Better Or Worse (NPR):
“Last October, Matt Herich was listening to the news while he drove door to door delivering pizzas. A story came on the radio about a technology that sends an electric current through your brain to possibly make you better at some things — moving, remembering, learning. He was fascinated.
The neurotechnology is called transcranial direct current stimulation, or tDCS for short. At its simplest, the method involves a device that uses little more than a 9‑volt battery and some electrodes to send a low-intensity electrical current to a targeted area of the brain, typically via a headset…Although researchers see possibilities for tDCS in treating diseases and boosting performance, it’s still an exploratory technology, says Mark George, editor-in-chief of Brain Stimulation, a leading journal on neuromodulation. And leading experts have warned against at-home use of such devices…
When Herich finished his shift delivering pizzas, he raced home and began googling. He found a thriving community on Reddit and other online forums dedicated to discussing ways to self-administer tDCS…Herich is not alone — beyond the DIY neurostimulation community, companies are cashing in on the phenomenon, offering brain stimulation kits and ready-to-wear headsets, like Thync and Halo. While the simplest devices can be made with items found in a hardware store, the best-selling versions like ActivaDose or the Foc.us can cost more than $300.”
