US military researchers have had great success using transcranial direct current stimulation (tDCS)– in which they hook you up to what’s essentially a 9-volt battery and let the current flow through your brain. After a few years of lab testing, they’ve found that they can more than double the rate at which people learn a wide range of tasks such as object recognition, maths skills, and marksmanship.(...)After trying it myself, I have different questions. To make you understand, I am going to tell you how it felt. The experience wasn’t simply about the easy pleasure of undeserved expertise. When the nice neuroscientists put the electrodes on me, the thing that made the earth drop out from under my feet was that for the first time in my life, everything in my head finally shut the fuck up.(...)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.
Putz! Tem gente fabricando esses dispositivos por conta própria:fonte: http://brmlab.cz/project/brain_hacking/tdcs
De onde saiu esse projeto? É o "oficial" dos militares americanos ou saiu da cabeça de algum inventor maluco de garagem?
