11. MAIN PRINCIPLE Main principle behind this interface is the bioelectrical activity of nerves and muscles. Brain is composed of millions of neurons. When the neuron fires, or activates, there is a voltage change across the cell which generates signals on the surface of the brain. By monitoring and analyzing these signals we can understand the working of brain.

20. EEG ELECTROENCEPHALOGRAPHY (EEG) IS MEASUREMENT OF ELECTRICAL ACTIVITY PRODUCED BY BRAIN AS RECORDED FROM ELECTRODES PLACED ON THE SCALP.

21. IMPLANT DEVICE The EEG is recorded with electrodes, which are placed on the scalp. Electrodes are small plates, which conduct electricity. They provide the electrical contact between the skin and the EEG recording apparatus.

27. FUTURE EXPANSION Thought-communication device. New research has demonstrated that it is possible for communication from person to person through the power of thought alone.This experiment goes a step further, with the aim was to expand the current limits of this technology and show that brain-to-brain (B2B) communication is possible. Super intelligent machines- Cyborgs. A Cyborg is a Cybernetic Organism, part human part machine. In the years ahead we will witness machines with an intelligence more powerful than that of humans.This will mean that robots, not humans, make all the important decisions .This may bring dire consequences for humankind.

28. CONCLUSION BMI’s will definitely have the ability to change the way a person looks at the world by giving people back their vision and hearing. But the question is that What kind of people are we becoming? Is someone with a synthetic eye, less a person than someone without? Shall we process signals like ultraviolet, X-rays, or ultrasounds as robots do? These questions will not be answered in the near future, but at some time they will have to be answered. What an interesting day that will be.
