paralyzed Person?

Can we enhance our strength?

Empower skills of

soldiers?

How this works?

Know your BRAIN !!

Nervous system sends ‘electric signals’ for sensation and perception.

Brain Computer Interface (BCI)

Direct communication pathway between an enhanced or wired brain and an external device.

They offers an alternative to natural communication and control

Principle:

The generated brain signals are interpreted using a computer software which converts and transmits the information to the implanted artificial organs.

Cursor movements

HARDWARE COMPONENTS

1 Brain Chip

2 Connector

3 Converter

4 Computer

BRAIN IMPLANT• Enhance capability

of human organs and senses

• Role in future genetic engineering fields and neuro sciencesuper human

artificial intelligence

Interface• Electroencephalograph (EEG) attached to the scalp.

• The electrodes can read brain signals.

• To get a higher resolution signal, scientists

can implant electrodes directly into the

gray matter of the brain itself, or on the

surface of the brain, beneath the skull.

Navigate Internet.

Play Computer Games.

Turn Lights On and Off.

Control Television. Control Robotic

Arm.

Applications:

1. Allow paralyzed people to control prosthetic limbs with their mind.

2. Allow gamers to control video games with their minds.

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

Uses

4. It acts as sensors that may soon assist failing memory, but even provide fluency in a new language

5. For lie detecting test

6. Mental Typewriter.

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).

Disadvantages: 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

 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.

Conclusion 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.

Future of genetic and nuero-engineering
