The Human Brain Essay - 1784 Words

The Human Brain The human being is considered to be the ultimate form of life on the earth. This is not because the human body is strong and agile. Many other animals posses skills much superior to humans and are able to perform feats humans can only dream of. The one thing that distinguishes humans from all of the other organisms on this planet is the brain. The brain is the site that controls the human body. However, unlike in animals, in man, the brain is also the site of the mind. The mind gives humans superiority over other creatures. It provides humans with the ability to reason, to feel and to adapt. Because of this, man has achieved so much, and has also realized that much more is still ahead. During†¦show more content†¦This increase in knowledge is partly due to the recent advances in nuclear medicine. Although X-ray machines have been the chief mechanical tools for internal observations of the human body since Wilhelm Roentgen discovered X-rays in 1901, the development of computers made it possible for better and more accurate techniques to be applied to scan the human body. These methods employ various scanners like the CAT, PET, MRI and SPECT. The CAT is an acronym for Computerized Axial Tomography. This method of scanning generally involves X-rays and enables scientists to view the inside of the head in a three dimensional format on a computer screen. PET stands for Positron Emission Tomography and it is much more complicated than the CAT scan. PET machines bombard the subject with doses of positrons -- the anti-matter equivalents of the electrons. As the positrons enter the body, they encounter electrons which are escaping from radioactive elements which have been injected into the bloodstream. When the positrons and the electrons collide, they give off energy which is recorded by a computer. The result is a far more detailed 3-D picture of the brain than the one obtained from the CAT machine. To obtain an even better image, physicians use the MRI, which stands for Magnetic Resonance Spectroscopy. With these threeShow MoreRelatedHuman Brain And Human Brains1477 Words   |  6 PagesWe, the human species are unique. This is a phrase we all have heard at some point in our lives. We are unique compared to other animals in our language, movements, and emotions. We have our own language which the majority of animals do not, we stand on two legs while the majority of the animals are on four legs, and we are much more sensitive to our emotional reactions, making us complex animals. Now, where does all these differences come from? As the title suggest, our human brains are incredibleRead MoreThe Brain And Its Effects On Human Brain1675 Words   |  7 Pages The brain has four main structures; the Cerebrum, Cerebellum, Limbic System, and the Brain Stem. The Cerebrum, also known as the Cerebral Cortex, is the largest part of the human brain. It is divided into four parts that are called â€Å"lobes†: there s the frontal lobe which is linked with reasoning, planning, parts of speech, emotions, and problem solving- the parietal lobe which is linked to movement, orientation, and recognitions- the occipital lobe which is linked to visual processing like objectRead MoreThe Perception Of The Human Brain s Brain953 Words   |  4 Pagesreason: survival†¦ as deep in the brain†¦we got special cells known as mirror neurons† (H. C. Sinclair, 2013). It also relates to current human behavior for the reason that it echoes the modeling or imitation behavior executed by children and adolescents. For example, individuals that are into Football will get worked up from just watching it due to similarly reacting to the responses of t he actual audience at the game. The reason as to why is because of the outcome of the human brain’s premotor cortex initiatingRead More The Human Brain Essay1341 Words   |  6 Pages Our brains weigh about three pounds and are divided into two similar looking but functionally different hemisphere, the right hemisphere and the left hemisphere. Both of which are connected by a large bundle of nerves called the corpus collosum. In some people with severe seizure disorders such as epilepsy, it was found that if this bundle of nerves was severed their seizure would either cease or a the very least be better controlled. From this surgical procedure it was discovered that the two hemispheresRead More The Human Brain Essay1189 Words   |  5 PagesThe human brain is a big, intricate—yet delicate, structure in the human body. It is the key structure in cognitive function. Any damage to the brain does not only â€Å"erase† memories but also may â€Å"deceive† th e brain to erroneously remember a new object as being familiar (2010). The innovative researchers at Cambridge University investigated this phenomenon in their research on The Paradoxial False Memory for Objects after Brain Damage. The publication began by stating the widely acceptable premiseRead MoreStress And The Human Brain1720 Words   |  7 Pagesof study for those interested in human sciences. In particular, stress is often viewed through the scopes of a Psychologist, Sociologist and an Anthropologist. The Psychologist s perspective revolves around relations between stress and the human brain. One of the questions they might ask would be if an individual can be born with stress. The answer is sometimes but not often. Researches at the University of Edinburgh found that mother’s wombs and babies brains contain a chemical protecting themRead MoreThe Human Brain : Is It Interesting?1764 Words   |  8 PagesI’ve never learned much about Psychology yet I always found it interesting.

Brain development begins in week four of their first trimester in the womb. This is important because the development helps a child learn and grow, effecting their future learning, education, and social skills. Brain development begins right in the womb and continues to flourish after birth. A child’s brain develops through neurons and their connections by synapses. Neurons communicate at synapses throughRead MoreThe Human Brain vs. the Computer1442 Words   |  6 PagesThe Human Brain vs. the Computer Over the millennia, Man has come up with countless inventions, each more ingenious than the last.
