4. INTRODUCTION
• The Brain chip technology is associated with a brain computer
interface chip, computer and brain.
• The Brain chip is so called because it is implantable computer chip
in brain.
• Brain Chip consists of both biological and electronics terms.
• Brain chips can enhance memory of human beings, help paralyzed
patients and are intended for military purposes.

5. WHAT IS A BRAIN CHIP ?
o A chip in the Braingate system is of 100 hair thin electrodes.
o It senses electromagnetic signature of Neutrons.
o The Brain chip provides fast and reliable connection between the brain of a
severely disabled person and personal computer

6.  The history of brain-computer interfaces (BCI) is very
old.
 BCI combines technologies from computer science,
electrical engineering, neurosurgery and biomedical
engineering .
 1875: Richard Canton first discovered electrical signals
on surface of animal brain.
HISTORY

7.  1950s: Jose Delgado, a neurosurgeon at Yale University,
invents the stimoceiver, an electrode device that can be
controlled wirelessly by FM radio. He tests it in the brain
of a bull and is able to make the animal charge and
change direction by the pushing of different buttons.
 June 2004: The first human, Matthew Nagle, is implanted
with a brain-computer interface.

8. The first patient, Matthew Nagle, a 25
year old man with a severe spinal cord
injury, has been paralyzed from the neck
down since 2001. Nagle is unable to move
his arms and legs after he was stabbed in
the neck.
First Experimented on ……

9.  With intact brain function, brain signals are generated even though they
are not sent to the arms, hands and legs.
 The signals are interpreted and transmitted into cursor movements.
Principle

10. HARDWARE COMPONENTS
THE CHIP
THE CONNECTOR
THE CONVERTER AND
THE COMPUTER

11. 1. The chip
• A Four millimeter square silicon chip studded with 100 hair-thin, micro
electrodes is embedded in brain’s primary motor cortex.
• The sensors detects tiny electrical signals generated when a user imagines.

12. 2. The Connector
The signal from the brain is
transmitted through the pedestal plug
attached to the skull.
3. The Converter
The signal travels to an amplifier where it is
converted to optical data and bounced by
fibre-optic cable to a computer.

13. • A brain-computer interface uses electrophysiological signals to control remote
devices.
• The Brain Computer Interface which are invasive is prerefrable.
• The electrodes pick up the brain’s electrical activity (at the microvolt level) and
carry it into amplifiers.
• These amplifiers amplify the signal approximately ten thousand times and then
pass the signal via an analog to digital converter to a computer for processing.
• The computer processes the EEG signal and uses it in order to accomplish tasks
such as communication and environmental control.
4. The Computer

14. BASIC BLOCK DIAGRAM OF A BCI SYSTEM INCORPORATING SIGNAL DETECTION,
PROCESSING AND DEPLOYMENT

16. ACHIEVEMENTS IN THIS FIELD
Brain “pace makers”
They are implantable neurons that would perform the function of a part of brain
that has been damaged by stroke or epilepsy...

17. RETINOMORPHIC CHIP
• Retinomorphic chip is a silicon device similar to the human eye, picks out the kinds
of features and facial patterns that we use to recognize people and read their
emotional state…

18. REMOTE CONTROLLED RAT
• Movement signals are transmitted from computer to the brain of rat
through a radio receiver strapped to its back.
• Military purposes and human rescue operations.

19. Applications:
• Navigate Internet.
• Play Computer Games.
• Turn Lights On and Off.
• Control Television.
• Control Robotic Arm.

20. For Mind Control.
 For depression.
 For seizures.
 For epilepsy.
 For Parkinson's.
 For hearing.
 For vision.
USED…..

21. • Biomedical Instrumentation,
• Micro electronics, signal processing,
• Artificial Neural Networks and Robotics which has
overwhelming developments.
• Hope these systems will be effectively implemented for many
Biomedical applications.
THIS TECHNOLOGY IS WELL SUPPORTED BY THE LATEST FIELDS OF

22. Benefits of Brain Chips
• It will increase the dynamic ranging of senses.
• It will give light to blind and give paralyzed
patients full mental control of limbs.
• No genetic modifications in the next generation.
• Rescue missions (remote controlled rat).

23. • Research is still in the beginning stages.
• The current technology is crude.
• Ethical issues may prevent its development.
• Electrodes outside of the skull can detect very few electric signals from the
brain.
• Electrodes placed inside the skull create scar tissue in the brain.
DISADVANTAGES:

24. DRAWBACKS
• Cost.
• Safety(non toxic materials).
• Losing Identity.
• Normal range people seen as subnormal.
• Risk for surgeons.

25. FUTURE OF BRAIN CHIPS
• It will enhance memory.
• It might enable “cyberthink”- invisible communication.
• Enable consistent and constant access to information
where and when needed.
• It will increase the dynamic range of senses, enabling,
for example, seeing IR, UV, and chemical spectra.

26.  The BrainGate helps the patients who cannot perform even simple
actions without the help of another person.
 Such paitents are able to do things like checking e-mails, turn the TV on
or off, and control a prosthetic arm with just their thoughts.
 BrainChip technology does not promise miracles.For instance, say that a
paralysed man will one day walk using an artificial leg by his thoughts
alone.
CONCLUSION

27. CONCLUSION
• Brain implants enhance capability of human organs and
senses.
• It has a significant role to play in future genetic
engineering fields and neuroscience.
• The implants may enhance your capabilities, but they
will expire when you do.
