Brain implant system
Designed for patients
with Amyotrophic Lateral
Sclerosis(ALS) or spinal
chord injury
The computer chip monitors
brain activity and converts it
to computer commands.
Page 3
Developed by bio-tech company
CYBERKINETICS in 2003.
At Brown University in conjunction
with Department of Neuroscience.

Aid paralyzed person to :
Control the electrical wheelchair
Communicate via e-mail and internet-
based-phone system
Operate television etc.
Page 5
An electrode chip is implemented in the brain
Electrical signals are exchanged
Signal are processed
Signal is sent to the computer
“Computer is CONTROLLED by the patient”

Human brain is capable of
processing instantaneously
large amount of information
An electrical data transmits
from brain to computer
Brain can be connected to
internet , robot or to a bionic
arm.

The computers translate brain activity
Computer create the communication
output using :-
Custom Decoding Softwares
Uses adaptive algorithms
Pattern-matching techniques
The algorithms are written in C,
JAVA and MATLAB.

In Fox borough , a 25-
year-old quadriplegic sits
in a wheelchair
In classification of EEG
signal.
In multimedia
communication.
As a brain controlled
switch.

Very expensive.
Information transform rate -
20 bits/min.
Difficulty in learning and
adaptation.
Algorithm used are not very
strong.

A completely implantable wireless device making Brain
Gate safer and less visible.
Future developments of brain-chip implants.
Within 10 years, it will be possible to "download” memory
implants for skill enhancement.
"Chipped” people will communicate with each other, using
just their thoughts – from anywhere on Earth.

According to the Cyber kinetics website, two patients have been implanted with the Brain Gate system.
In early test sessions, the patient can carry on a conversation
The results are spectacular and almost unbelievable.
Brain Gate can help paralyzed people move
