A new research article published by the University of Washington reveals some amazing, but potentially unnerving, technological advances. Researchers were able to create a brain-to-brain interface that literally allowed one subject to THINK about an action and another to actually ACT on that thought. The experimenters essentially used a visuomotor task in which two subjects cooperated to achieve a goal in a computer game communicating solely through direct brain-to-brain interaction. One subject literally thought about completing the task while the other conducted the task, successfully. The researchers previously found a method for subjects to essentially link brain signals to actions. The scientists were able to record brain signals using an electroencephalography (EEG) and link such signals with transcranial magnetic stimulation (TMS), which delivers information to the brain. In the latest experiment, researchers were able to record the thoughts, using an EEG, of one subject and link those thoughts to the other subject using TMS, which caused the impending action of the second subject. "In the experiment, each sender was placed in front of a computer game that involved firing a cannon and intercepting rockets to protect a city. The senders, however, were unable to physically interact with the game. They could only defend the city by thinking about moving their hands to fire the cannons and intercept the rockets. Meanwhile, the corresponding receivers sat in a distant, dark room with no ability to see the game and their right hands positioned over touchpads that controlled the game. The senders were hooked to EEG machines that read brain activity, and their partners wore caps equipped with technology to stimulate the part of the brain that controls hand movements. When the senders thought about moving their hands to shoot the cannon, their partners’ brains received the message to do so via signals sent from their partners’ brains to theirs over the Internet. [Accuracy among the pairs varied from 25 to 83 percent, but the researchers found that most misses were caused by senders failing to accurately execute the “fire” command, not by failure on the receivers’ ends."](http://betabeat.com/2014/11/its-now-possible-for-one-persons-brain-to-control-another-personss-movements/) [Read the original research article here.](http://www.plosone.org/article/fetchObject.action?uri=info:doi/10.1371/journal.pone.0111332&representation=PDF)
