Among available brain stimulation techniques, transcranial direct-current stimulation (tDCS) is a fairly simple non-invasive method for cortical stimulation.
A recent study, conducted by researchers at the University of New Mexico, seems to support the cognitive-enhancing effect of the technique.
Learning and performance in a shooting video game was increased two-fold following 30-min tDCS as compared to control, even after one-hour delay.
Other studies found beneficial tDCS effects on working and visual memory.
Capitalizing on the enthusiasm generated by these studies, the website GoFlow is planning to offer a DIY kit for tDCS with a price tag of $99!
Understandably, the kit is very bare-bone, and includes only a battery, a few scalp electrodes, resistor, and a potentiometer.
I would venture to guess that the kit would attract avid brain-hacking enthusiasts and perhaps some students desperately trying to memorize the material before the exam.
For the rest of us, let’s wait for a more mature product to hit the shelves.
