Abstract
Brain gate is an electrode chip which can be implemented in the brain.
When it is implemented in brain, the electrical signal exchanged by neurons
within the brain.
Those signals are sent to the brain and it executes body movement. All the
signaling process is handled by special software. The signal sends to the
computer and then the computer is controlled by patient.
Objective of Brain Gate
The goal of the Brain Gate program is to develop a fast and reliable
connection between the brain of a severely disabled person and a personal
computer . The ‘Brain Gate’ device can provide paralysed or motor-impaired
patients a mode of communication through the translation of thought into
direct computer control.
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, functions, brain signals signals are generated 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” to control
a computer with thought, just as individuals who
have the ability to move their hands.
CONCLUSION
According to the Cyberkinetics website, two patients have been implanted with
the Brain Gate system.
Using the system, called Brain Gate, the patient can read e-mail, play video
games, turn lights on or off and change channels or adjust the volume of a
television set.
The results are spectacular and almost unbelievable.
Brain Gate can help paralyzed people move by controlling their own electric
wheelchairs, communicate by using e-mail and Internet-based phone systems,
and be independent by controlling items such as televisions etc.
Finally BRAIN GATE has proved to be a boon for paralyzed patient
