What is Brain Gate/Brain Machine Interface/Brain Computer Interface?
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.
Whenever a man forgotten about his past due to certain accidental matter or he had lost his part of his body, at that time this electrode chip can be implemented on his brain and active the man as well.
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
It Worked
Using only its mind the monkey was able to control a cursor on a computer monitor via Brain Gate
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
APPLICATIONS
In Foxborough, a 25-year-old quadriplegic sits in a wheelchair with wires coming out of a bottle-cap-size connector stuck in his skull. The wires run from 100 tiny sensors implanted in his brain and out to a computer. Using just his thoughts, he was playing the computer game Pong
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.
In early test sessions, the patient was able to control the TV and carry on a conversation and move his head at the same time.
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 and thermostats.
Finally BRAIN GATE has proved to be a boon for paralyzed patient .
