Brain zapping helps US Navy Seals learn faster

The Navy wants soldiers who can concentrate better and learn faster, and it's looking at a controversial piece of tech to do that: transcranial electrical stimulation. It has been testing a passive brain-stimulating device from Halo Neuroscience with "a small group of volunteers" from Seal Team Six, the group that killed Osama Bin Laden, and other units, according to Military.com. "Early results show promising signs," said spokesman Capt. The $749 Halo Neuroscience headset (below) looks a lot like regular headphones, and does actually play music. However, it also has silicon spikes on the band called "neuroprimers" that contact a wearer's head.
