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

Brain Computer Interface (BCI)
![Page 10: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/10.jpg)
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.

BRAIN IMPLANT• Enhance capability
of human organs and senses
• Role in future genetic engineering fields and neuro sciencesuper human
artificial intelligence
![Page 18: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/18.jpg)
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
![Page 21: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/21.jpg)
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.
![Page 22: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/22.jpg)
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).
![Page 23: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/23.jpg)
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
![Page 24: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/24.jpg)
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.
![Page 25: Brain Computer Interface (BCI) - seminar PPT](https://reader035.vdocument.in/reader035/viewer/2022082202/58cfd1de1a28ab13238b46dd/html5/thumbnails/25.jpg)
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
