The document discusses Brain Gate technology, which involves implanting an electrode chip into the brain that can detect electrical signals from neurons. These signals are then sent to a computer and translated into commands via specialized software, allowing paralyzed patients to control external devices with their thoughts. Key points include that Brain Gate was developed in 2008 to provide communication for paralyzed patients, animal research demonstrated brain signal detection in rats and monkeys, and it works by translating detected brain activity into computer outputs.

3. INTRODUCTION
• Brain gate is an electrode chip which
can be implemented in the brain.
What is Brain gate
Technology?

4. INTRODUCTION(cont.)
 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.

5. OBJECTIVE
 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 paralysed or
motor-impaired patients a mode of communication
through the translation of thought into direct computer
control.

6. DEVELOPMENT
 Brain Gate Technology by Bio-tech Company Cyber Kinetics in 2008 in
conjunction with the development of Neuroscience at Brown University.
Nicholas Halso

7. BRAIN COMPUTER INTERFACE
 A Brain computer interface called as direct
neural interface or brain machine interface is a
direct communication pathway between
human or animal brain and an external device.
 “BCIs” usually connects the brain(or nervous
system) with a computer system

8. BCI Technology(cont.)
 Based on the communicative pathway BCI
is classified as follows
One way BCIs
Two way BCIs

9. BCI Technology(cont.)
 One way BCI:Computers either accept commands from the brain or send
signals to it(for example, to restore vision)but not both.
 Two way BCI:Brains and external devices can exchange information in
both directions but have yet to be successfully implanted in animals or
humans.
 Brain Computer interface is of three types based on its features and are
 Invasive BCI
 Partially Invasive BCI
 Non Invasive BCI

10. ANIMAL RESEARCH

11. RESEARCH ON ANIMALS
 At first ,rats were implanted with BCI.
 Signals recorded from the cerebral
cortex of rat to operate BCI to
carry out the movement.

12. RESEARCH ON ANIMALS
 Researchers at the University of
Pittsburgh had demonstrate on a
monkey that can feed itself with a robotic
arm simply by using signals from its
brain to carryout the movement.

13. A BOON TO THE PARALYZED -BRAIN
GATE NEURAL INTERFACE SYSTEM:
 Mathew-Nagel the first
person to use the brain-
computer interface to
restore functionality lost
due to paralysis…..

14. WORKING

15. WORKING
 The Brain Gate neural interface device is a
propriety brain-computer interface that consist
of an Inter neural signal sensor and
External processors.
 The sensor consists of a tiny chip containing
100 microscopic electrodes that detect brain
cell electrical activity.
 The chip is implanted on the surface of brain
in the motor cortex area that controls
movement.
 The computers translate brain activity and
create the communication output using
custom decoding software.

16. ADVANTAGES
 Controlling remote devices.
 Making and receiving telephone calls
 Accessing the internet.
 Turn on or off the lights.
 Control robotic arm.
 Watch and control television
 Use the pc
 Locking or unlocking doors
 Motorized wheelchair

17. DISADVANTAGES
 Expensive
 Risky Surgery
 Not wireless yet
 Difficulty in adaptation and learning
 Limitation in information transform rate.
 The latest technology is 20 bits/min.

18. Conclusion
 The invention of Brain gate is such a revolution in medical field . The
remarkable break through offers hope that people who are paralyzed will
one day be able to independently operate artificial limbs ,computers or
wheelchairs.
 The idea of moving robots not by manual control , but by mere “thinking”
(i.e., the brain activity of human subjects) has been a fascinated approach.
