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.
3. 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 ?
4. 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
5. NeuroChip
A chip in the braingate system uses 100 hair thin
electrodes
It sense electromagnetic signature of Neutrons
6. 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
7. 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
output
9. Chip Implimentation in Brain
There will be two surgeries, one to implant the Braingate and one to remove it. Before surgery, there will
be several precautionary measures in order to prevent infection; patients will have daily baths with
antimicrobial soap and take antibiotics.
In addition, MRI scans will be done to find the best place on the brain for the sensor. Under sterile
condition and general anesthesia, Doctor will drill a small hole into the skull and implant the sensor
Patients will receive post-surgical care including a CT scan, some blood tests, and wound care in the
hospital 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, then
monthly and as needed.
11. 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.
13. Disadvantages
Has not been approved by FDA
Has been approved for pre-market clinical
trials
No estimate on cost
14. 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
15. 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
16. 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
