BRAIN GATE TECHNOLOGY is a boon for ppl met with accidents leading to spinal cord failure,,,,, THIS technology brings ray of hope and sunshine in their life
2. Brain Gate Technology developed by Bio-tech company Cyber
kinetics in 2008 in conjunction with the department of
Neuroscience at Brown University.
Development
Nicholas Halso
3. NEED OF BRAIN GATE TECHNOLOGY
• 300,000 Americans are spinal cord injured.
• 52% of spinal cord injured individuals are
considered Partial paralysis and 48% Total
Paralysis
• Approximately 15,000 new injuries occur each
year.
• 82% are male.
• 56% of injuries occur between the ages of 16
and 30
5. The brain-machine interface analyzes
slight changes in the brain's blood
flow and translates brain motion into
electric signals.
6. Brain-Computer Interface
• A brain–computer interface (BCI) is a direct
communication pathway between a brain and
an external device computer interface (BCI).
• It’s also known as direct neural interface or a
brain–machine interface.
• Brain computer interface takes place as a result
of EEG

7. Brain Signals & Electroencephalogram
(EEG)
• EEG is a recording of the electrical activity of the brain directly from
the scalp produced by the firing of neurons within the brain.
• No EEG signal pattern is duplicated for any two distinct actions
How EEG Works ?
• Recordes patterns by placing small metal discs called electrodes on
the scalp in certain positions
• Each electrode is labeled with a letter and a number to indicate its
position.

8. How the Signal is Produced
• EEG machines use differential
amplifiers to produce each
channel or trace of activity.
• The EEG signal itself is in the
waveform so it is required that
an analogue to digital signal
converter be employed to
produce the signal as a series of
numeric values each
representing voltage values of
each channel at a certain time
instance.

10. A TINY CHIP HOLDING 100
MICROSCOPIC ELECTRODES
• The Braingate Neural Interface device consists of a tiny chip
containing 100 microscopic electrodes that is surgically
implanted in the brain's motor cortex. The whole apparatus is
the size of a baby aspirin. The chip can read signals from the
motor cortex, send that information to a computer via
connected wires, and translate it to control the movement of
a computer cursor or a robotic arm. According to Dr. John
Donaghue of Cyberkinetics, there is practically no training
required to use Brain Gate because the signals read by a chip
implanted, for example, in the area of the motor cortex for
arm movement, are the same signals that would be sent to
the real arm.
12. WORKING
• The sensor of the size of a contact lens is implanted in
brain’s MOTOR CORTEX which control hand and arm
movements. A tiny wire connects the chip to a small
pedestal secured in the scull. A cable connects the
pedestal to a computer. The brain's 100bn neurons fire
between 20 and 200 times a second .The sensor
implanted in the brain senses these electrical signals
and passes signals to the computer through the cable.
The computer translates the signals into a
communication output, allowing a person to move a
cursor on a computer screen merely by thinking about
it.
13. Brain Gate Sensor Implantation
and Post-Op Recovery as Planned
• Surgery as planned
• Post-op recovery unremarkable
• Wound healing around pedestal
• complete
Array
on Cortex
Insertion
2 months post implant
21. A boon to the paralyzed
• Mathew-Nagel the first person to use the brain-
computer
• interface to restore functionality lost due to
paralysis…
22. Biggest reward
• On 7th november 2009 toyota launched it’s
wheel chair that works on thought
• It has a reaction time of 123 milliseconds
23. Wachowski brothers' movie trilogy "The Matrix," humans dive into a
virtual world by connecting their brains directly to a computer……
24. CONCLUSION
• The invention of Brain gate is such a
revolution in medical field.
WITH A BRAIN GATE YOU CAN:
Turn on or off the lights on your room
Check and read E-mails
Play games in computer
Use your PC
Watch and control your Television
Control a robotic arm
