I’m researching the “BrainGate” here which is a Neural- interface system on an embedded chip in the brain planted in the cerebral cortex that “allows human thought to be detected and read as complex electrical or neural patterns.”  I came across this article in the Irish Times that brought up the subject of the “BrainGate” which got me into researching it: http://www.irishtimes.com/newspaper/sciencetoday/2012/1108/1224326303333.html where it states…(Excerpt)…

“Getting a cup of coffee using mind control 

Last May, scientists from America’s Brown University in collaboration with the US Department of Veterans Affairs successfully tested a small chip, known as the BrainGate device, to allow a paralysed woman to control a robot by thought alone.

The chip is implanted inside the skull and sits on the surface of the brain near the cerebral cortex. It is capable of detecting and transmitting neural signals generated deep within the cortex.The woman was able to operate a robotic arm by active mind control to bring a beaker to her lips. (A video of the system in action is available at iti.ms/XjHi6O.)

The chip is essentially a neural- interface system that allows human thought to be detected and read as complex electrical or neural patterns. The chip interprets these patterns and converts the signals into orders that can be transmitted to the electronic control systems of assistive technologies, such as communications systems or robots.

Pilots in fighter jets use electronic “slave systems” that allow cameras within the cockpit to direct precision guided munitions on to large numbers of targets. The BrainGate technology would allow “drone” pilots the ability to actively control the slave systems of combat UAVs remotely.”

From there I did a search and found a “BrainGate” Timeline here:

BrainGate has reached many milestones over the last nine years. Below, some highlights. (Return to news release.)

2000

Six Brown University scientists plan to explore the function of the human brain using tiny electronics — nanotechnology — with a $4.25-million grant from the U.S. Department of Defense.

2001

Cyberkinetics Neurotechnology Systems Inc. launches under a licensing agreement with the Brown University Research Foundation, based on research and technology developed in part in the lab of neuroscientist John Donoghue, director of the Brown University Brain Science Program.

2002

Researchers at Brown University show that signals from the brain, which normally control hand movement, can be decoded and used as the sole input to control a computer cursor. Their report appears in the March 14 issue of Nature.

2004

The BrainGate™ Neural Interface System receives an investigational device exemption from the U.S. Food and Drug Administration, which allows Cyberkinetics to begin testing the device in patients.

2004

Brown and the Providence VA Medical Center receive a five-year, $4.75-million grant to form the Brown-VA Center for Restorative and Regenerative Medicine. The new venture is focused on rebuilding, restoring, and regenerating function for veterans after limb loss.

2005

Brown and Cyberkinetics sign a research and licensing agreement, allowing access for eligible neuroscience researchers at Brown to human clinical data gathered during testing of the BrainGate™ Neural Interface System.

2006

A team led by Brown and Massachusetts General Hospital researchers publish early pilot clinical trial results that show the BrainGate brain sensor allowed a person with tetraplegia (paralysis of both arms and both legs) to open a prosthetic hand, control a robotic limb and move a computer cursor — using thoughts alone. The work was featured on the cover of Nature.

2007

Brown and research partners at Cyberkinetics and the Cleveland Functional Electrical Stimulation Center agree to develop new brain implants that record or stimulate neural activity which may be used in patients with paralysis, epilepsy and other central nervous system injuries and disorders.

2009

The U.S. Food and Drug Administration provides an investigational device exemption to begin a new BrainGate trial. Dubbed BrainGate2, the trial will be run at the Massachusetts General Hospital, with Brown, MGH and the VA Medical Center all playing vital roles in the research.
