BRAIN GATE TECHNOLOGY
[attachment=66087]
INTRODUCION
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.
BRAIN COMPUTER INTERFACE
Brain-computer interface (BCI) is a
collaboration between a brain and a
device that enables signals from the
brain to direct some external activity
such as control of a cursor or
a prosthetic limb
Brain Computer Interface(BCI) is a
direct communication pathway
between the brain and an external device
PRINCIPLE
The system consists of a sensor that
is implanted on the motor cortex of the
brain (Pedestal) and a Brain Gate
Neural Interface Device that analyzes
the brain signal. The principle is that
the intact brain functions, brain signals
are generated even though they are not
sent to the arms , hands and legs .
The signals are interpreted and
translated into cursor movements ,
offering the user an alternate
”BRAIN GATE PATHWAY”.
The Neuro chip
A 4-millimeter square silicon chip studded with 100 hair-thin microelectrodes is embedded in the primary motor cortex the region of the brain responsible for controlling movement
The connector: When the user thinks “move cursor up and down”, the cortical neurons fibre in a distinctive pattern which the signal is transmitted through the pedestal plug attached to the skull
Working
The Brain Gate neural interface device is a propriety brain-computer interface that consist of an Inter neural signal sensor and External Motor Cortex 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
Software behind Brain Gate
The computers translate brain activity and create the communication output using custom decoding software.
System uses adaptive algorithms and pattern-matching techniques to facilitate communication. The algorithms are written in C, JAVA and MATLAB
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 Brain gate 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.
The idea of moving robots or prosthetic devices not by manual control, but by mere “thinking” (i.e., the brain activity of human subjects) has been a fascinated approach
