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, the initiator of body movement, 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 one organ in such a small mass could be responsible for all the functions of the human body, hearing, taste, emotions, love, yawning, seeing by blinking and many other functions. Scientists had learned more about the human brain than in precious years. The human brain still remained a sensitive field of research for most scientists. However, brain research is still being conducted for further inventions and technological upgrades in science. The amputations have sparked a new revolt among scientists over how to combine robotics (artificial parts) and the human brain. Every handshake, step or movement of a body part is the consequence of the brain exchanging information with an arm or leg. However, the main question in this situation is: what would happen if the connection between the limb and the brain was interrupted? This is known as amputation. What exactly does the term amputation mean? According to the dictionary definition, amputation is the removal of a major body part, whether by prolonged constriction or surgery. According to research conducted by the National Center for Health, thirty percent of people have an amputation... mid-paper... due to the problem of scar tissue forming against foreign materials. Although they are safe, they have poor signal quality. They are widely used in artificial limb movement 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 image above he breaks down brain-machine interfaces into the types of BMIs scientists use to combine brain function and robotic parts and limbs. EEG is a measurement of the electrical activity produced by the brain recorded by 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 It is the foundation of current BMI research.
