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

man to control a computer using his Thoughts.  The system is to help those who have lost control of their limbs, or other bodily functions, such as patients with spinal cord injury to operate various gadgets such as TV, computer ,lights, fan etc.  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 in 2003 in conjunction with the Department of Neuroscience at Brown University.

WORKING PRINCIPLE  The principle of brain gate neural interface system is that which

intact with brain function, neural signals generated are interpreted by the systems and a cursor is shown to the user on a computer screen that provides an alternate “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.  The sensor consists of a tiny chip containing 100

microscopic electrodes that detect brain cell electrical activity.  The chip is implanted on the surface of brain in the

motor cortex area that controls movement.

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 M*Power 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.
