Based on Cyber Kinetics Platform Technology.
Principle is intact brain function, brain
signals are generated .
It is an electrode chip implemented in the
brain.
Implementation in brain leads to the electrical
signal exchanged by neurons within the brain.
Those signals are sent to the brain and it
executes body movement.
All the signaling process is handled by special
software.
The signal sends to the computer and then the
computer is controlled by patient.
The sensor consists of a tiny chip (smaller
than a baby aspirin) with one hundred
electrode sensors each thinner than a hair
that detect brain cell electrical activity.
One way BCI Computers either accept
commands from the brain or send signals to
it
Two way BCI Allow brains and external
devices to exchange information in both
directions
The goal of the Brain Gate program is to
develop a fast and reliable connection
between the brain of a severely disabled
person and a personal computer .
The ‘Brain Gate’ device can provide
paralyzed or motor-impaired patients a mode
of communication through the translation of
thought into direct computer control
The electrode
translates brain
activity and sends the
information to the
computer in a format
it can understand.
Brain Gate uses a sensor that is implanted
onto the motor cortex of the brain.
The device analyzes
brain signals then
interprets and
translates them into
Cursor movements.
At first, rats were implantedwith BCI .Signals recorded from the cerebral cortex of rat to operate BCI to carry out the movement.
Researchers at the University of Pittsburgh had demonstrated on a monkey that can feed itself with a robotic arm simply by using signals from its brain.
It Worked! Using only its mind the
monkey was able to control a cursor on a
computer monitor via Brain Gate.
Since there were no complications in
trials with monkeys Next Step: Humans
The first patient, Matthew Nagle, a 25-yearold man with a severe spinal cord injury, hasbeen paralyzed from the neck down since2001.
During 57 sessions, Nagle learned to opensimulated e-mail on the computer using onlyhis thoughts.
He could change the
channel and adjust the
volume on a television,
even while conversing.

It can provide paralyzed or motor-impaired
patients a mode of communication through
the translation of thought into direct computer
control.
