Braingate technology is a neural interface system that allows paralyzed individuals to control computers and devices through brain signals. Developed by Cyberkinetics, it involves implanting a sensor in the brain to interpret and transmit neuronal signals to a computer, facilitating actions like moving a cursor or controlling devices. While it holds great promise for restoring mobility and independence, it is still in pre-market clinical trials and has not yet received FDA approval.

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.

10. Advantages
 Designed to one day allow the user to interface with the computer

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.

12. Advantages
 Faster than what is possible with the hands of a non- disabled
person

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
