Based on Cyber Kinetics Platform Technology.

Principle is intact brain function, brain

signals are generated .

Page 3: Brain gate  ppt prem (5010)

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

Page 7: Brain gate  ppt prem (5010)

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.

Page 10: Brain gate  ppt prem (5010)

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.
