Could a Nine-Volt Battery Be Better than Coffee? – Casey Research

What if the mind-state attained by world-class athletes and brilliant physicists – the flow – were available to everyone, at minimal cost and without breaking any law? Would people go for it?

We’re about to find out. The hottest new topic in brain research these days involves a technique called “transcranial direct current stimulation,” or tDCS for short.The setup couldn’t be simpler: Clamp a set of electrodes to the head, pass a miniscule direct electric current 2 milliamperes or less through the brain for 20-30 minutes, and presto, instant immersion in the flow state. The whole thing can be run off of a common nine-volt battery.
