Introduction

Braingate is an electrode chip which can be implemented in the

brain. When it is implemented in brain, the electrical signal

exchanged by neurons within the brain. Those signals are sent to

the brain and it executes body movement. All the signalling process

is handled by special software. The signal sends to the computer

and then the computer is controlled by patient.

What is Braingate Technology ?

History

After 10 years of study and research,

Cyberkinetics, a biotech company in

Foxboro, Massachusetts, has developed

Braingate in 2

Dr. John Donaghue, Rhode Island, and

chief scientific officer of Cyberkinetics, lead

the team to research and develop this brain

implant system in 2003

Following year of animal experimentation,

early working implants in human now exist,

designed to restore damaged hearing, sight

and movement

With recent advances in technology and

knowledge, pioneering researches could

now conceivably attempt to produce BCIs

that augment human function rather simply

NeuroChip

A chip in the braingate system uses 100 hair thin

electrodes

It sense electromagnetic signature of Neutrons

Principle

With intact brain function, brain signals are

generated even through they are not sent to the

arms, hands and legs

The signals are interpreted and transmitted into

cursor movements

Working

Braingate Neural Interface device consist of sensor, a

cable and pedestal and a cart. It is proprietary brain

computer interface

The sensor is implanted in brain’s percental gyrus

A tiny wire connects the chip to a small pedestal

A cable connects the pedestal to a computer

The sensor senses the electrical signals & passes to

the pedestal

Pedestal passes this signal to the computer

Computer translates the signal into communication

Chip Implimentation in Brain

There will be two surgeries, one to implant the Braingate and one to remove it. Before surgery, there willbe several precautionary measures in order to prevent infection; patients will have daily baths withantimicrobial soap and take antibiotics.

In addition, MRI scans will be done to find the best place on the brain for the sensor. Under sterilecondition and general anesthesia, Doctor will drill a small hole into the skull and implant the sensorPatients will receive post-surgical care including a CT scan, some blood tests, and wound care in thehospital for 1 to 5 days after surgery.

After surgery, one of the study doctors will see the patients at least once at a week for six weeks, thenmonthly and as needed.

Advantages

Designed to one day allow the user to interface with the computer

Advantages

It is a boon to a Disabled Person

Mathew Nagel is the First person to use the

Braingate technology to restore functionality loss

of his limbs due to paralysis.

Advantages

Faster than what is possible with the hands of a non- disabled

person

Disadvantages

Has not been approved by FDA

Has been approved for pre-market clinical

trials

No estimate on cost

Applications

Multi device patient ambulation system

Biological interface system with patient training

apparatus

Biological interface system with surrogate controlled

device

Limb and digit movement system

Mental typewriter

WITH A BRAIN GATE YOU CAN

Turn on or off the lights of a room

Check and read E-mails

Play games in computer

Use PC

Watch and control Television

Control a robotic arm

Conclusion

The invention of Braingate is such a

Revolution in medical field. The

remarkable breakthrough offers hope

that people who are paralyzed will

one day be able to independently

operate artificial limbs, computers or

wheelchairs
