INTRODUCTION Brain Chip Technology is a technology that involves brain

implants.

Brain Chip Technology implements the brain computer interface.

Brain Gate is a brain implant system or a device that was designed to help those who have lost control of their limbs, or other bodily functions.

INVASIVE

Invasive BCIs are implanted directly into the grey matter of the brain during neurosurgery.

Invasive devices produce the highest quality signals of BCI devices but are prone to scar- tissue build-up.

7

SEMI AND NON-INVASIVE

Electrocorticography (ECoG)

Electroencephalography

fMRI = Functional Magnetic Resonance Imaging

Magnetoencephalography (MEG)

ANIMAL BCI RESEARCH

During 2000, open loop BCI was implemented.

PROJECTS OF BCI

Brain gateHonda asimo controlGaming controlBionic eye

10

BRAIN GATE

The sensor, which is implanted into the brain, monitors brain activity in the patient and converts the intention of the user into computer commands.

11

HONDA ASIMO CONTROL

Researchers have developed an interface for Honda's Asimo robot that allows individuals to control it simply by thinking.

12

GAMING CONTROL

Gaming control using a

wearable and wireless EEG-

based brain-computer

interface device with novel

dry foam-based sensors.

13

BIONIC EYE

A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness

14

ADVANTAGES

Allow paralyzed people to control prosthetic limbs with their mind.

Allow gamers to control video games with their minds.

Allow a mute person to have their thoughts displayed and spoken by a computer.

Mental Typewriter.

15

DISADVANTAGES

Research is still in beginning stages

The current technology is crude

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

16

CONCLUSION

Brain Chip Technology is a technology which involves communication based on neural activity generated by the brain.

It gives paralyzed patients greater ability to interact with their environments.

The Brain Gate Neural Interface creates a direct link between a person's brain and a computer, translating neural activity into action.
