Brain chips are hybrid devices that allow for the transfer of information between computer chips and brain cells. They consist of electrodes implanted in the brain that detect electrical signals, which are then transmitted to an external computer via a connector and converter. This allows severely disabled individuals to control external devices with their thoughts by translating brain signals into commands. While promising for communication assistance, brain chips face challenges from scar tissue formation and limitations in the number of detectable brain signals. Further research is still needed to fully realize their potential.

2. • 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’s consist of both biological and electronic terms.
• The study on neural implants i.e brain chip was started early in 1970
by a yale professor named Jose Manuel Rodriguez Delgado.
INTRODUCTION

3. WHAT ARE BRAIN CHIP’S?
• Brain Chip’s are hybrid entities where Chip’s
and nerve cells establish a Close physical
interaction allowing the transfer of
information in one or both directions.
• Brain Chip’s provide fast and reliable
Connection between the brain Of severely
disabled person and computer.

4. HARDWARE COMPONENTS

.The connector
.The convertor
.Computer

5. THE CHIP
• A four millimeter Square silicon Chip
studded with 100 hair-thin ,micro electrodes
is embedded in brain’s primary motor cortex.
• The sensor detects tiny electical signals
generated when a user imagines.

6. THE CONNECTOR
• The signal from the brain is transmitted
through the pedestal plug attached to
the skull.

7. THE CONVERTOR
• The convertor converts the brain signals
into wireless data for the purpose
of action.
• The signal travels to an amplifier where
it is converted to an optic data and
and bounded by fibre-optic cable to a
Computer.

8. THE COMPUTER
• A brain-computer interface uses electro
physiological signals to control remote
devices.
• The electrodes pick up the brain’s
electrical activity (at the microvolt
level) and carry it into amplifiers.
• These amplifiers amplify the signal
approximately 1000 times and then pass
the signal via an analog to digital
convertor to a computer for processing.

9. WORKING
• The nerve cells in our brain are receiving,
interpreting and responding to the bombardment
of Information.
• They produce impulses as electric signals.
• These electric signals are received by the chip
and this chip convert these signals to human
understandable language by means of
Computer.

10. SOFTWARE BEHIND BRAIN CHIP
• Software behind braingate system uses algorithms and Pattern
matching techniques to facilitate communication.
• The algorithms are written in C, JAVA and MATLAB.
• Signal processing software algorithms analyses the electrical
activity of neurons and translates it into control signals for use in
various computer – based applications.

11. ADVANTAGES
• Allow paralyzed people to control prosthetic limbs with their mind.
• Allow gamers to control video games with their minds.
• Allow a mental person to have their displayed and spoken by a
computer.
• Mental type writer.

12. DISADVANTAGES
• Research is in still beginning stages.
• Electrodes outside of the skull can detect very few electric sigals
from the brain.
• Electrodes placed inside the skull create scar tissue in the brain.

13. CONCLUSION
• Brain chip technology is a technolog which involves communication
based on neural activity generated by brain .
• It gives paralyzed patient greater ability to interact with their
environments.
• The brain gate neural interface creates direct link Between person’s
brain and a computer ,translating neural activity into action.
