The document provides an overview of brain-computer interfaces (BCI). It discusses the history of BCI beginning with Hans Berger's discovery of EEG in 1924. The document describes how BCI works and the different types including invasive, partially invasive, and non-invasive. It outlines applications for BCI including communication for disabled people and device control. Both advantages like enabling independent living and disadvantages like high cost and slow speed are mentioned.

3. Introduction :
A Brain computer Interface (BCI) is
a Direct communication pathway between a
Human or animal brain( or Brain cell
culture) and an External Device.
Sometimes called a Direct Neural
Interface or a Brain Machine Interface
(BMI).
Goal:
Enabling People (especially disabled) to
communicate and control device by mere thinking.

4. History of BCI :
 The History of BCI starts with
HANS BERGER’S discovery of the
electrical activity of the Human
brain and the development of
ElectroEncephaloGraphy (EEG).
 In 1924 Berger was the first to
record human brain activity by
means of EEG.

5. History of BCI :
Jacques vidal started BCI
Research in year 1970 at university
of California Los Angles.
In 2003,BCI was commercially
developed by CyperKinetics Bio-
Tech company.
In 2013,Duke university
successfully connected direct brain
to brain Interface of the two rats.

6. How the BCI works..?

7. Types of BCI :
 Invasive BCI
 Partially Invasive BCI
 Non-Invasive BCI

8. Invasive BCI :
Invasive BCI are implanted
directly into the grey matter
of the brain during
Neurosurgery.
 It built the scar tissue.

9. Partially Invasive
BCI :
Partially Invasive BCI are
implanted inside the skull
but rest outside the brain
rather than within the grey
matter.
 Low risk for Scar tissue.
Cathy Hutchinson

10. Non-Invasive BCI :
Non-Invasive BCI do not
involve Neurosurgery.
 Easy to wear

11. Application :
Disabled people to communicate
Device Control
Safe and Security
Gaming & Entertainment

12. Advantage :
BCI made easier life for the Physically
(or)mentally disabled peoples.
It has significant role to play in future genetic
Engineering field & Neuroscience.
Transmit auditory data to the mind of deaf
person,allowing them to use.
Allow the paralysed patient to control
prosthetic limb with their mind.

13. Disadvantage :
 High Cost
Slow speed
Require extensive training
Virus attack may occur & causing ill effect to
Brain.

14. Conclusion :
 Open Gate for Disable peoples.
BCI for totally paralyzed person.
A Potential therapeutic tool.
Enable People to communicate and
control appliance with use of brain signal.
