UK to Use Brain Science to Create Cyborg Super-Soldiers:

The wide-ranging document reportedly covers a lot of ground, including the ethical issues surrounding the use of neuroscience in defense. It seems to focus less on ways to impact the enemy directly, and more on the enhancement of soldiers’ fighting abilities—though neurological drugs that make enemy captives more talkative or perhaps cause enemy troops fall asleep or become disoriented also get a mention.

Of particular interest in the document: transcranial direct current stimulation, or tDCS. The idea of passing electrical signals through the skull to the brain to boost performance isn’t new to U.S. defense dreamers, as the U.S. military has already done tests on the technology (and found it helpful in improving soldiers’ abilities to detect threats). A battle helmet that can pass weak electrical pulses through the brain could sharpen a soldier’s mind, the report suggests, upping attention spans and memory as well as attention to detail.

Similarly, electroencephalogram (EEG) could work to turn the human brain into a more efficient tool, although in a somewhat backwards fashion from tDCS. Using an array of electrodes, EEG can record brainwaves through the skull, detecting things that may not be conscious but that the brain nonetheless registers. For instance, the report cites DARPA research in which subjects looking at satellite photos were monitored with EEG. Even when the subjects missed some of the targets they were looking for in the images, the brain detected them, and that was evident in their brain waves even though it was never converted to conscious thought.
