According to scientists, electrical stimulation of the brain of just a few milliamps can alleviate depression, help with learning, and reduce the cravings for a cigarette, just to name a few. Since all it takes is "some resistors, current regulators, and a 9-volt battery, [...] a mix of technophiles, hackers, and self-improvement hopefuls" have started hacking their own brains.
That clearing of the head is what drew Mario Abundis, a 30-year-old software engineer based in Los Angeles, Calif., to the technology. “I firmly believe we don’t know even one percent of our potential or what we can do with a healthy mind,” he said.
Abundis uses the commercially available Foc.us headset marketed for gaming. He described the effects of tDCS as if his brain suddenly did not need to hold information in RAM to be available. Instead, “you are in such a perfect calm state. Anything you need you can go and grab from the hard drive right away,” he said.
