The brain is the most complex part of the human body. The weight of the human brain is three pounds. This three-pound organ controls the seat of intelligence, the interpreter of the senses, the initiator of body movements and the controller of behavior (reference). The human brain is like a living network of parts that interact and work together; each part has its own properties. All these parts working together control the human body. The parts that work together are the forebrain, midbrain, and hindbrain. It is beyond the ability to imagine that an organ of such a small mass could be responsible for all functions of the human body, from hearing, taste, emotions, love, yawning , blink vision and many other functions. Scientists have learned more about the human brain than in precious years. The human brain still remains a sensitive area of ​​research for most scientists. However, research is still being carried out on the brain for new inventions and scientific technological updates. The amputations have sparked a new uprising among scientists over how to combine robotics (artificial parts) and the human brain. Every handshake, step, or movement of a body part is the outgrowth of the brain that exchanges information with an arm or leg. However, the main question in this situation is: what would happen if this connection between the limb and the brain was broken? This is called an amputation. What exactly does the term amputation mean? By dictionary definition, an amputation is the removal of a main body part, whether by prolonged constriction or surgical intervention. According to research carried out by the National Health Center, thirty percent of people with amputations...... middle of paper ......face the problem of scar tissue forming against foreign bodies. Although they are safe, they have poor signal quality. They are widely used in the movement of artificial limbs and organs. EEG, MEG, and MRI are widely used technologies in the invasive brain interface category. EEG is the most studied non-invasive brain interface. In the illustration above, she breaks down brain-machine interfaces into the types of BMIs used by scientists to combine the function of the brain and robotic parts and limbs. EEG is a measure of electrical activity produced by the brain recorded from electrodes placed on the scalp. An electroencephalogram (EEG) is a measurement of brain voltage fluctuations detected by scalp electrodes. It is an approximation of the cumulative electrical activity of neurons. This is the basis of current BMI research..
