According to this article at Arstechnica, Medical researchers are manipulating electrical activity in the brain with electrodes and have found that stimulating the primary motor cortex can help people learn.
The authors focused on a learning task, one they describe as similar in principle to the process we go through when we learn a new sport. …One group of subjects received a current; the controls had electrodes attached, but received no current.
By the end of day one, those who had an anode placed near the primary motor cortex were already pulling away from their peers (a cathode had no effect), and had opened up a large and significant gap by the end of day five.
Can anyone get a good deal USB powered brain altering electrodes? On second thought, there may be some liability concerns here…
