Brain Machine Interfaces Essay

2057 words - 9 pages

The brain is the most complex part of the human body. The weight of the human brain weighs three pounds in mass. This three-pound organ controls the seat of intelligence, the interpreter of the senses, initiator of body movement and controller of behavior (reference). The human brain is like a live network of parts that all interact and work together; each part has their own properties. All these parts that work together control the human body. The parts that work together are the Forebrain, midbrain and the hindbrain. It is beyond ones capacity to imagine that an organ in such a small mass can be responsible for all the functions of the human body, hearing, tasting, emotions, love, ...view middle of the document...

This fact had meant that each amputation had consisted of 350,000 persons, which had only been in the United States of America. These quantitative numbers presented above open one’s mind on how to create a new technology that would make daily tasks easier for them to perform and bring back their normal life again. This was the trigger that had opened the minds of scientists in combining both the functions of the brain with computers and robotic limbs.
It was hard to anyone to build direct functional interfaces between brain and artificial has moved a stunning pace since the first experimental demonstration in 1999 that direct signals of cortical neurons could directly control a robotic manipulator .since then, a continuous stream of research paper regarding the brain-machine interfaces, this interest come from the considerable potential of this technology for restoration of motor behaviors in severely a handicapped patients.
Which further research the BMI system had been a (a thought). BMI which stands for the brain-machine interfaces. BMI technology is based on the finding that with intact brain function, neural signals are generated even though they are not sent to the arms, hands and legs (references).
In the previous year’s scientists had decided combine both the functions of the brain with computers and robotic limbs. The brain machine interfaces, had stated that a decade ago hardly anyone can predict any attempts to build a direct functional interfaces between brains and artificial devices. (Reference). Early research for brain interfaces was made on animals specifically monkeys; they use the recorded signals coming from the monkey’s cerebral tissues in order to operate brain interfaces devices to carry out movement. After a time and training the monkey, by only thinking about the task, the monkey success to navigate the computer cursors on screen and command robotic arm to perform simple tasks. Brain-Machine interfaces (BMI) or brain-computer interfaces (BCI),also call “Neuron-prostheses” ,it is simply interfaces between a machine and the brain of the user , this implies that neural impulses generated by user’s brain are detected, elaborated and utilized by the machine, approximately in real-time, to do many tasks as arm reaching and hand grasping movements in artificial actuators or limbs.
Researchers worked to create a system that could continuously tap into diverse populations of neurons, convert their signals into commands a robot could understand, and then immediately transmit those commands to the machine. Basic science research in animals helped identify three essential components to a brain-machine interface: simply thinking of an action activates motor-control neurons; the signals from hundreds but not thousands of motor neurons are needed to imitate natural movement; and sensory feedback is necessary for proper control of a brain-directed prosthetic.(reference)
There are many different parts in the human brain. However the...

If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation
