The Controller of Humans The Brain Essay - 758 Words

The human brain is composed of many important parts of everyday life. The exterior part of the brain has 9 part in which include are divided into different sections, lobes, cortex, and areas. Within the lobes, it includes frontal, parietal, occipital, and temporal lobes. In cortexes, it has the motor cortex, and the sensory cortex. Within the areas section it includes Broca’s Area. The cerebellum is a small version of the brain, and the cerebrum is the like the whole brain. Although the brain is about three pounds blood flows through the brain about 750-1,000 milliliters (mL) per minute, (Disabled World, 2008) (Brain Trivia, (n.d.)). The brain is quite small but there is still a little brain, the cerebellum. The cerebellum function is to†¦show more content†¦Largest of the lobes, handles brain thinking functions (Frontal Lobe: (n.d.)). This lobe is located in front of the central sulcus (Lobes of the Brain, (n.d.)). The cortex responsible for coordination of planning, control, and executing voluntary movements is the motor cortex. Motor areas are located in both hemispheres meaning it is located in between. The motor cortex of the left hemisphere control right side of the body. The motor cortexes of the right hemisphere control the left side of the body. Three parts make up the motor cortex. Which are the primary motor cortex, the premotor cortex, and the supplementary motor area (The Motor Cortex. (n.d.)). Broca’s Area generates speech, writing, language processing and comprehension (Cold Spring Harbor Laboratory, (n.d.)).Named after French scientist Paul Broca. Scientist believe that we speak with the left-brain. Located in the front part of the left hemisphere. Lies specifically in the third frontal convolution. Broca’s Area contains motor neurons involving the control of speech. (Encyclopedia of Britannica, (n.d.)). Within the lobes, the parietal lobe lies in that category. This lobes function is to stimuli touch, pressure, temperature, and pain (Lobes of the Brain, (n.d.)). This parietal lobe is divided into two parts, superior parietal and the inferior parietal lobe. Neurons receive sensory information from skin and tongue. This then processes information from the ears and the eyes (Parietal Lobe, (n.d.)).

One of the most common arguments for skepticism is the Brain in a Vat argument, which is very similar to the argument of the Evil Demon who controls us. In opposition to this is a philosopher by the name of Hilary Putnam, who uses language as proof for us not being brains in vats. I am going to explain to you why I think that Putnam is correct. â€Å"If you cannot be sure that you are not a brain in a vat, then you cannot rule out the possibility of all of your beliefs aboutRead MoreComparison of Mustapha Mond from Brave New World and Captain Beatly from Fahrenheit 451772 Words   |  4 Pagesmany ways. They both are similar because of the power or strength they have over people and the way they brain wash them. Captain Beatty somehow persuades people to believe that books are contain unpleasant and contradicting facts and opinions that should be destroyed. But there were just some people that thought otherwise. Then there’s Mustapha Mond who is the world state leader/controller. There Society is very creep and unusual. Mustapha creates stability in London and makes them control otherRead MoreThe Issue Over The Existence Of Free Will Essay1555 Words   |  7 Pagesthe investigation into consciousness. Although we have first person access to our conscious brain, the advancement of technology has allowed previously inaccessible understanding of what goes on inside our heads. But much of our brain and spinal cord, the scientifically agreed upon location of the self, is barely understood. But as we apply reason and testing to our theories, we can learn more about the brain from a scientific and philosophic viewpoint. We can finally marry the two fields through anRead MoreBiomechatronics: Analyzing Human Motion Essay553 Words   |  3 Pagesthat interact with the body’s muscles and nervous system with the aim to enhance human movement. Dr. Hugh Herr, a leading scientist and his t eam are working on developing biomechartonics using computer models and camera analyses to study the movement of balance. (How Stuff Works Inc, 2005) They are also researching how electronic devices can be interfaced with the nervous system (implanting electrodes into the brain, muscles and surface galvanic electrodes on skin. The first prosthetic limb was recordedRead MoreBrain-Computer and Brain-Machine Interfaces Applied to the Medical Field1780 Words   |  7 PagesOver the years, brain-computer interfaces (BCIs), or brain-machine interfaces (BMIs), have advanced into a technology that can be regularly be applied to the medical field. BCIs have been used for rehabilitative purposes, such as patients suffering from loss of speech and motor functions. Every year, approximately 795,000 people suffer a stroke. Out of these people, 600,000 of these are first attacks and 185,000 are recurrent attacks [9]. Stroke patients often suffer from paralysis and loss of speechRead MoreEssay on Wireless Technologies1515 Words   |  7 PagesWireless data has become the technology of the future. Data is being passed from one location to another without the human eye detecting this transaction. Wireless data is transferred in many forms from home networks, business networks, and cellular networks. Each of these networks operates on a different scale and technology. Home networks have been steadily growing over the years as manufacturers have developed new and easier to use devices that install quickly and give the owner the abilityRead MoreThe Effects Of Pressurized Cabins On The Human Body2029 Words   |  9 Pagesare. Dalton’s Law states â€Å"The human body is affected by the pressure of gases available, meaning as someone is acceding the percent of oxygen remains constant but there are fewer molecules the higher someone is† (Reinhart). Since there are fewer molecules the body becomes starved of oxygen and then the effects of hypoxia begin to develop and the first symptoms will begin to develop. This is where machines will come in to help the human body survive. However, the human body is great at adapting toRead MoreThe Faults Of The Power Grid1733 Words   |  7 Pagesgrid includes over-current, over-voltage and short circuit. It is also a harsh reality that this problems cannot be to some extent kept in mere attention of humans, whose capability and speed to some extent are limited. Hence a fast acting mind is required that takes care of this problem. To solve this problem PLC (Programmable logic controller) comes into the picture. It is used to operate relays (a type of switch) which in turn assists the CB (circuit breaker) to isolate the faulty part from theRead MoreThe Mind Body Problem : Phineas Gage1489 Words   |  6 Pagespierces an area of your brain. Those who have had a frontal lobotomy, whether purposefully or not, have had their personality changed permanently. An unlucky foreman of the Rutland Railroad, Phineas Gage, was on the receiving end of a tragic occurrence that severed the frontal lobe area of his prefrontal cortex. He underwent the experience of having a railroad spike pierce him beneath his left cheek and exit through his skull, consequently injuring an important area of his brain. This occurrence changedRead MoreApplication Of Sdn And Its Architectural Principle1365 Words   |  6 Pagesconsolidated infrastructure. By abstracting cloud resources using software defined networking, it’s easier to collect cloud resources. The networking components that make up massive data centre platforms can all be managed from the Software Defined Network controller. iii. Directly Programmable : Networks are directly programmable because the control functions are separated from forwarding functions. Directly programmable enables the network to be programmatically configured by patented or open source automation
