CONTENT Introduction Development Working Principle Types of Brain Computer Interface(BCI) Applications Advantages Disadvantages Future Scope Conclusion

INTRODUCTION It is a mind-to-movement system that allows a

quadriplegic person to control a computer using his Thoughts.

It monitors brain activity in the patient and converts the intention of the user into computer commands

This can be used to control a robot arm or a cursor on a screen

DEVELOPMENT Company and Scientist:

Brain Gate is a brain implant system developed by the bio-tech company Cyber kinetics with the Department of Neuroscience at Brown University.

Nicholas Halsopulas

WORKING PRINCIPLE

The principle of brain gate neural interface system is that

which intact with brain function is known as “Brain

Gate pathway".

The user can use that cursor to

control the computer, just as a mouse is used.

TYPES OF BRAIN COMPUTER INTERFACE(BCI)

One way BCI Computers either accept commands from the

brain or send signals to it Two way BCI Allow brains and external devices to exchange

information in both directions.

WORKING

The Brain Gate neural interface device is a

propriety brain-computer interface that consist of

an Inter neural signal sensor and External

Processors.

WORKING (CONT…) External Processors convert neural signals into

an output signal under the users own control.

The computers translate brain activity and

create the communication output using custom

decoding software.

APPLICATIONS In classification of

EEG(Electroencephalography)signal. In multimedia communication. Actuated control of mobile robot by human

EEG. As a brain controlled switch for asynchronous

control. In evaluating the machine learning algorithms.

ADVANTAGES Controlling remote devices Making and receiving telephone calls Accessing the internet. Turn on or off the lights Control robotic arm Watch and control television Use the pc Locking or unlocking doors Motorized wheelchair

DISADVANTAGES Expensive Risky Surgery Not Wireless yet Difficulty in adaptation and learning. Limitation in information transform rate. The latest technology is 20 bits/min.

FUTURE SCOPE Current new advances include a second-

generation interface software controller that will enable users to perform a wide variety of daily activities without assistances of technician.

Smaller ,wireless device . The user will have an improved control of

respiratory system, limb with muscle stimulation or robotics.

CONCLUSION The invention of Braingate is such a revolution

in medical field. The remarkable breakthrough offers hope that people who are paralyzed will one day be able to independently operate artificial limbs, computers or wheelchairs.
