BRAIN-COMPUTER INTERFACE
Organization:• A brief introduction of BCI• Know your brain• How does BCI work?• Experiments and researches• Applications• Is it harmful?• Queries
A Brief Introduction to BCI
• BCI(Brain Computer Interface), often called Mind Machine Interface(MMI) or Direct Neural Interface(DNI).
• It is a technology to communicate human brain directly to a computer or any communication device without any physical contact.
• The history starts with Hans Berger’s discovery of electrical activity of human brain and EEG in 1924.
• The research on BCI began on 1970 at the University of California Los Angeles.
Know Your Brain
•The human brain is divided into two parts:a. Cerebral cortexb. Subcortical regions.
•Research focused on Cerebral cortex system.
•Cerebral cortex is subdivided into two hemispheres :a.Left hemisphere b.Right hemisphere
How Does BCI Works?
• The BCI works on the principle of Electroencephalography (EEG) and fNIRS (Functional near IR spectroscopy).
• There are two methods to interface brain with computer:
a. Invasive b. Non-invasive.
• Generally EEG is preferred for the experiment .
• EEG uses non-invasive method.

In 2002 Jens Naumann was successfully implanted artificial eyes
Experiments and Researches
• May 2008, Monkey operated a robotic arm by thinking in University of Pittsburgh Medical Center.
University if Washington researchers have performed first brain to brain communication
Applications1. Communication:
2. Gift for handicapped or physically disabled people:
3. Robotics:
4. Virtual Reality:
Is It Harmful?• Ethical issues.
• Invasive method can create scar tissue in the brain.
• Will make human lazy.
