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, yawning, blinking vision and many more functions. Scientists had learned more about the human brain, than in the precious years. The human brain had still remained a sensitive field of research for most scientists. However still researches are being conducted on the brain for further invents and technological updates in science. Amputations had triggered a new uprising of thinking in scientist on how to combine between robotics (artificial parts) and the human brain.
Every handshake, footstep or movement of a body part is the outgrowth of the brain exchanging information with an arm or leg. However the main question in this situation is what if that link between the limb and the brain was severed? This is known as an amputation. What is exactly does the term amputation mean? According to the dictionary definition an amputation is a removal of a body part of the main body, whether it’s by a prolonged constriction or a surgery. According to research that had been done by the National Center for Health, that thirty percent of people have amputatio...

...ent the scar tissue formation problem against the foreign materials. Although they are safe they have poor signal quality .They are extensively used in the artificial limbs movement and organs. EEG, MEG, and MRI are widely technology used under the category of invasive brain interface. EEG is the most studied non-invasive brain interface.

In the imagine above it breaks down the Brain- machine interfaces into the types of BMI that are used by scientists to combine the function of the brain and the robotic parts and limbs.
EEG is measurement of electrical activity produced by brain as recorded from electrodes placed on the scalp. An electroencephalogram (EEG) is a measure of the brain’s voltage fluctuations as detected from scalp electrodes It is an approximation of the cumulative electrical activity of neurons It is the foundation of current BMI research’s.

Brain-Computer Interfaces Essay

- Until recently, our relationship with technology has been limited to physical and direct command. To get a device to take action, you must touch it, or speak to it. All of this could change with this new technology called, brain-computer interfaces. This amazing technology will not only revamp military applications, but most importantly help the medical community substantially. It brings the possibility of sound to the deaf, sight to the blind and movement to the physically challenged....   [tags: Brain-Computer Interface]

Ethical Assessment of Implantable Brain Chips Essay

- Ethical Assessment of Implantable Brain Chips My purpose is to initiate a discussion of the ethics of implanting computer chips in the brain and to raise some initial ethical and social questions. Computer scientists predict that within the next twenty years neural interfaces will be designed that will not only increase the dynamic range of senses, but will also enhance memory and enable "cyberthink" — invisible communication with others. This technology will facilitate consistent and constant access to information when and where it is needed....   [tags: Science Neurology Technology Ethics Papers]

Brain Computer Interface Essay

- BRAIN COMPUTER INTERFACE The ability to interact directly with the human brain came about due to advances in cognitive neuroscience and brain imaging technologies. This is all made possible with the use of sensors that can monitor some of the physical processes which take place within the brain and correspond with certain forms of thought. Once such technology which have arisen due to these advances is the brain computer interface (BCI). This is also referred to as brainwave computing, thought controlled computing, mind controlled computing or thought interpreting computer software and programming, (Shah, 2014)....   [tags: human brain, imaging technologies]

The Human Brain Is A Well Oiled Machine Essays

- The human brain is a well-oiled machine. It requires maintenance like any other mechanism. The brains ability to cognitively function is affected by many factors within a person’s surrounding environment. Cognitive abilities began to develop during the early stages of childhood. In newer generations, children have developed shorter tempers, awry cognitive abilities and bleak imaginations. Scientific researchers have labeled upcoming generations as nature deficient. Many scientists, researchers and naturalists blame the innovations in technology for keeping children glued to their video game controllers and game devices; however, they acknowledged that it would be a short-sighted research pro...   [tags: Psychology, Brain, Attention, Cognition]

Essay on Understanding The Neural Mechanisms Of Natural And Adaptive Behaviors

- The human body can be thought of as an intricate machine and the brain as the control panel. This complex organ that has kept scientists and philosophers involved over the centuries ultimately controls how we function. The brain, to me, is the most interesting thing in the universe. However, much is still undiscovered and therefore it intrigues us to learn more about this vital organ. My fascination with the brain arose while taking introductory biology and psychology courses. My deepened interest towards the neural basis of memory and learning and its impacts on neurodegenerative diseases such as Alzheimer’s eventually lead me to attain an undergraduate research opportunity in the Mizumori...   [tags: Brain, Psychology, Laboratory]

Essay on Technology Advancements in Computer Interfaces

- Technology Advancements in Computer Interfaces According to the Shelly Cashman Series of Office text books the 2 primary input devices used are the keyboard and mouse (Shelly, 2011). Since information management devices (i.e. personal computers, smart phones, and entertainment consoles) the technology and function have expanded vastly. The more function and operation we need out of our devices the more responsive and versatile we need these devices. We still need the standard keyboard and mouse for most information processing, but now to interact with device we find it common place to touch the screen directly....   [tags: keyboards, mouse, gestures]

Types Of User Interfaces Are Command Driven Essay

- Three types of user interfaces are command driven, interface menu driven, and interface graphical user interface. A command line interface is basically just a plain screen, usually white text on a black background, such as MS-DOS or the Command Prompt in Windows, where a user can type in commands into the input. As an overall statement, a CLI requires that the user know their material in order for it to be effective. The CLI offers users enormous elasticity in that a single command can be executed with a range of arguments, but the effectiveness is in direct proportion to how many commands and arguments for a command that the user is aware of....   [tags: Graphical user interface, User interface]
