Monkeys Control Robotic Arm With Brain Implants

'Scientists in North Carolina have built a brain implant that lets
monkeys control a robotic arm with their thoughts, marking the first
time that mental intentions have been harnessed to move a mechanical
object.'

'The ability to make machines that respond to thoughts rests on some
fundamental properties of the nervous system. The brains of monkeys
plan every movement the body carries out fractions of seconds before
the movements actually occur. Motor plans are in the form of electrical
patterns which arise from cells that fire at the same time, from
various parts of the brain. The plans are sent to spinal cord neurons
that have direct access to muscles. Only then are movements carried
out.' .. 'To link brains and machines, researchers place electrodes
directly into parts of the brain that produce motor plans. They
extract raw electrical signals that can be translated mathematically
into signals that computers and robots understand.' ... 'There is
preliminary evidence that humans produce the same sorts of motor
signals as monkeys in planning movements.'

'Dr. Tony Tether, Director Defense Advanced Research Projects Agency
(DARPA) DARPATech 2002 Welcoming Speech...' .... 'When I say bio
revolution, I really mean just that. I have reviewed over the past year
hundreds of projects, both ongoing and proposed. However, there is one
project that has struck me the most. DARPA has a monkey at Duke
University, where probes were implanted into its brain. The unique
factor of these probes is that they were not rejected. They have been
in the monkey for over a year now without any harmful effect. The
monkey was given a joystick and taught that to receive a treat, the
monkey had to move the joystick. The signals from the implant were
transmitted to a mechanical arm also grasping a joystick. The
mechanical arm was taught to move in the same manner as the monkey's
arm. So, when the light came on, the monkey moved the joystick in order
to get the treat. The signals were then sent over the Internet, of
course, to MIT where the mechanical arm was located and the mechanical
arm moved its joystick.' .. 'Now that is terrific, but that is not the
chilling part. We took the joystick away from the monkey at Duke. The
light came on. Who knows what the monkey really thought, but it knew
what it had to do. But it had no joystick. However, the mechanical arm
at MIT moved the joystick just like it did before. It was thought at
first that the motor signal was being transmitted to MIT, but it turned
out that the probes had tapped into the monkey's thoughts for moving
the joystick. In other words, the monkey thought about moving the
joystick, and the joystick at MIT moved.' .. 'This has tremendous
possibilities. I don't know how long this is going to take, perhaps 25
years or more. But it will happen. The genie is out of the bottle on
this possibility, and the nation that first gains this capability will
dominate.' .. 'Imagine 25 years from now where old guys like me put on
a pair of glasses or a helmet and open our eyes. Somewhere there will
be a robot that will open its eyes and we will be able to see what the
robot sees. We will be able to remotely look down on a cave and think
to ourselves, "Let's go down there and kick some butt." And the robots
will respond, controlled by our thoughts. It's coming. Imagine a
warrior—with the intellect of a human and the immortality of a
machine—controlled by our thoughts.' .. 'DARPA has started a major
program in this area. DARPA is the only place you can have such a
program, and talk about it! This is a great time to be in R&D.' ...
'Who are these future warfighters? Do we know them? You bet we do; they
are our children.' .. 'The theme of DARPATech 2002 is "Transforming
Fantasy." Our fantasies today will be their reality in the future. And
that's the most motivating factor of all.'
