Abstract: Brain Gate was developed by the bio-tech company Cyberkinetics in 2003 in Conjunction with the department of h:euroscience Brown University. The device was designed to help those who have lost control of their limbs or other body function. The computer chip u-hich is implanted into the brain, monitors brain activity in the patient and convert the intension of the user into computer hands. Currently the chip used 100 hair-thin electrodes that hear neurons firing in specific area of the brain. For e.g.: the area that control the arm movement .the acti\-it\- is translated into eclectically charged signals and are then set and decoded using a proLmm thus mo\.in,o the arm. According to the Cyberkinetics website, 2 patients have been implanted ivith the Brain Gate. The Brain GateTM System is based on Cyber kinetics' platform technology to sense, transmit, analyze and apply the language of neurons. The S>.stem consists of a sensor that is implanted on the motor cortex of the brain and a device that anal~.zesb rain signals. The principle of operation behind the Brain GateTM System is that nrith intact brain function, 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 GateTM pathway" to control a computer with thought, just as individuals who have the ability to move their hands use a mouse
