Dr. Mike Weisend is a senior research scientist at the Wright State Research Institute in Beavercreek, Ohio. He’s a neuroscientist who worked on developing something called neuroimaging-guided transcranial direct current stimulation, or tDCS.
Basically, it’s a device that uses electricity to stimulate your brain in all the right places.
tDCS works by passing a small current using twenty-two electrodes placed on your body (with at least one on your head). The idea here is that, because your brain runs on electricity passing the electrical current through, the tDCS should change the way the brain works, allowing you to affect behavior.
What Dr. Weisend and his team did in particular was to (literally and figuratively) enhance that process.
