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.

The 20 minutes I spent hitting targets while electricity coursed through my brain were far from transcendent. I only remember feeling like I had just had an excellent cup of coffee, but without the caffeine jitters. I felt clear-headed and like myself, just sharper. Calmer. Without fear and without doubt. From there on, I just spent the time waiting for a problem to appear so that I could solve it.

It was only when they turned off the current that I grasped what had just happened. Relieved of the minefield of self-doubt that constitutes my basic personality, I was a hell of a shot. And I can’t tell you how stunning it was to suddenly understand just how much of a drag that inner cacophony is on my ability to navigate life and basic tasks.

That is why I’m now allowing Michael Weisend, who works at the Mind Research Network in Albuquerque, New Mexico, to hook my brain up to what’s essentially a 9-volt battery. He sticks the anode – the positive pole of the battery – to my temple, and the cathode to my left arm. “You’re going to feel a slight tingle,” he says, and warns me that if I remove an electrode and break the connection, the voltage passing through my brain will blind me for a good few seconds.

Weisend, who is working on a US Defense Advanced Research Projects Agency programme to accelerate learning, has been using this form of transcranial direct current stimulation (tDCS) to cut the time it takes to train snipers. From the electrodes, a 2-milliamp current will run through the part of my brain associated with object recognition – an important skill when visually combing a scene for assailants.
