  • Aggressiveness Brain Success - 1,125 words
    Aggressiveness + Brain = Success Aggressiveness + Brain = Success Nowadays, the women in Asia are receiving more and more reputations than before. In China the most successful and welcomed TV anchormen are the men and women half to half and the female anchormen have much more chance to take part in some TV series show than their male colleagues; even the national woman soccer team of China, after they acquired the second prize in the World Cup last year, their brilliant glory erased our male soccer players incompetence. Women, especially the Asian women, are no longer those whom only had to stay at home taking care of her husband and children, making dinners and cleaning the houses to spend ...

  • Alzheimers Disease Is A Progressive And Irreversible Brain Disease That Destroys Mental And Physical Functioning In Human Bei - 725 words
    Alzheimer's Disease is a progressive and irreversible brain disease that destroys mental and physical functioning in human beings, and invariably leads to death. It is the fourth leading cause of adult death in the United States. Alzheimer's creates emotional and financial catastrophe for many American families every year. Fortunately, a large amount of progress is being made to combat Alzheimer's disease every year. To fully be able to comprehend and combat Alzheimer's disease, one must know what it does to the brain, the part of the human body it most greatly affects. Many Alzheimer's disease sufferers had their brains examined. A large number of differences were present when comparing the ...

  • Alzheimers Disease Is A Progressive Degenerative Disease Of The Brain That Causes Increasing Loss Of Memory And Other Mental - 564 words
    Alzheimers disease is a progressive degenerative disease of the brain that causes increasing loss of memory and other mental abilities. The disease attacks few people before age sixty, but it occurs in about twenty percent of people who live to age eighty-five. The disease is named after the German psychiatrist and neuropathologist Alois Alzheimer, who first described its effects on brain cells in 1907. Symptoms of Alzheimers disease come in three stages: early, late, and advanced. Early stages include forgetfulness of recent events, increasing difficulty in performing intellectual tasks such as accustomed work, balancing a checkbook or maintaining a household. Also, personality changes, inc ...

  • Brain Cancer - 635 words
    Brain Cancer The body normally forms new cells only when they are needed to replace old or damaged ones. If something happens to disturb this controlled process, abnormal or excessive cells are produced. When this occurs a tumor is developed. This is known as cancer. When a tumor is developed on the brain, it is called a brain tumor or brain cancer. Brain tumors can be benign or malignant (benign being not cancerous and malignant being cancerous). Both types can be deadly when dealing with the brain. Benign brain tumors consist of very slow growing cells. They have distinct borders and rarely spread to other locations. When viewed under a microscope, the cells of a benign tumor have an almos ...

  • Brain Lateralization - 287 words
    Brain Lateralization Language comes naturally to human and is one of the attributes that distinguish us from animals. It is an innate trait, which enables a child to master a language at an early age. Researches showed that the critical age and the cognitive specialization of the brain might have played a part in this. However language needs nurturing in a way of proper exposure to ensure its smooth progress. Whatever it is, the knowledge of the factors above does register some significance to me personally. I am now planning to expose my children to more than one language before they reach the schooling age. Probably Malay and English, which of course will involve my husband and I conversin ...

  • Brain Scans Show Pattern In Violent Behavior - 485 words
    Brain Scans Show Pattern In Violent Behavior Murderers and other people prone to violence have distinct brain patterns that can be scanned and that might be changed with drugs and other therapies, researchers said. Most people's brain can rein in overreaction to emotions such as fear or anger. But in pathologically violent people, this control system gets short-circuited. Several studies have shown this rewiring can be seen in images such as PET(positron emission tomography) scans. Impulsive,affective aggression may be the product of a failure of emotion regulation, University of Wisconsin-Madison psychologist Richard Davidson and colleagues wrote in their report, published in journal scienc ...

  • Brain Structure - 312 words
    Brain Structure The part of the body that motivates eating is the hypothalamus. The small gland is located in the midline at the base of the brain, just below the hypothalamus, and interacts closely with the pituitary gland and acts in coordination with the reticular formation. The two components of the hypothalamus dealing with hunger are the lateral hypothalamus and the ventromedial nucleus. The lateral part is what allows a person to feel hungry and sends out signals to the rest of the body that one is ready to eat. If this part is damadged, one would not feel hunger and would experience aphasia, which is starving. The ventromedial nucleus gives satiety, or the feeling that one is full. T ...

  • Canadas Declining Health Care System And The Brain Drain - 883 words
    Canadas Declining Health Care System And The Brain Drain Canada's Declining Health Care System and the Brain Drain Canada's government-funded health care system in under attack. Despite the mandate of the Canada health act, which was meant to assure universality, comprehensiveness, equitable access, public administration and portability of our health care system, (Braithwaite 17), Canadians today make the issue of health care their most important political concern. One of the biggest crises the Canadian health care system faces is for strange reasons not in the spotlight when debating the issues, that is the brain drain-Canada losing highly skilled physicians and health care workers to other ...

  • How Does The Brain Perceive - 1,338 words
    How Does the Brain Perceive How does a human hear? When an object makes a noise, it sends vibrations (better known as sound waves) speeding through the air. These vibrations are then funneled into your ear canal by your outer ear. As the vibrations move into your middle ear, they hit your eardrum and cause it to vibrate as well. This sets off a chain reaction of vibrations. Your eardrum, which is smaller and thinner than the nail on your pinky finger, vibrates the three smallest bones in your body: first, the hammer, then the anvil, and finally, the stirrup. The stirrup passes the vibrations into a coiled tube in the inner ear called the cochlea. The fluid-filled cochlea contains thousands o ...

  • Left And Right Brain - 661 words
    Left And Right Brain Psychology Right Brain, Left Brain The human brain is a miraculous organ. It regulates thought, memory, judgment, personal identity, and other aspects of what is commonly called mind. It also regulates aspects of the body including body temperature, blood pressure, and the activity of internal organs to help the body respond to its environment and to maintain the body's health. In fact, the brain is considered so central to human well-being and survival that the death of the brain is considered in many parts of the world to be equal legally to the death of the person. In the past fifteen years or so there has been a lot of talk of left brain and right brain people. Clear ...

  • Leinigen And Brain - 788 words
    Leinigen And Brain The human brain needs only to become fully aware of its powers to conquer even the elements. The human brain is powerful and controls all of a person's body. It easily compared to the central processing unit in a computer; all information is received, transferred, and sent back out. Without it nothing would work. Leiningen, a plantation farmer, was persistent and followed this motto to help him overcome many elements, or "acts of God." Leiningen had met and defeated these elements which had come against him unlike his fellow settlers who had little or no resistance. Something terrible was coming, about a hundred yards wide, a flood of ants. All people except Leiningen, who ...

  • Right Brain, Left Brain - 798 words
    Right Brain, Left Brain Psychology The article in which I chose to examine is called Right Brain, Left Brain: Fact and Fiction, written by Jerre Levy. In the past fifteen years or so there has been a lot of talk of left brain and right brain people. Levy's reason for righting this article was clearly to stop the misconceptions and show the truth about how our brain hemispheres operate. Levy first explores the myth of the left brain and right brain theory. She states that generally people see the left hemisphere of the brain controlling logic and language and the right, creativity and intuition. In addition people differ in their styles of thought, depending on which half of the brain is domi ...

  • Schizophrenia Is A Serious Brain Disorder It Is A Disease That Makes It Difficult For A Person To Tell The Difference Between - 1,128 words
    Schizophrenia is a serious brain disorder. It is a disease that makes it difficult for a person to tell the difference between real and unreal experiences, to think logically, to have normal emotional responses to other, and to behave normally in social situations. People with schizophrenia may also have difficulty in remembering, talking, and behaving appropriately. Schizophrenia is one of the most common mental illnesses. About 1% of the world population has schizophrenia. In the United States, there are about 2.5 million people with the disease. Schizophrenia is the cause of more hospitalizations than almost any other illness. Schizophrenia most commonly begins between the ages of 15 and ...

    ... FUTURE Today many experiments are being conducted that may be break through's for the future. For instance "brain grafting" is one procedure that may be used in the future. Brain grafting is to transplant a very thin layer of brain skin from one person to another. This would result in control of parkinson's disease and other seizure related diseases. Another radical idea that has already been successfully been tried on rhesus monkey's is, brain transplants. The ethics and legal problems for such a transplant would probably never let this operation be performed on humans. This is because the person would not be the same, would not have the same memories or the same abilities that the host ...

  • The Brain - 1,018 words
    The Brain A.M.D.G 27th October 1996 The Brain By Manuel Socarrs In the central nervous system of animals, the brain is a segregated group of nerve cells, or neurones, within the cranium, or skull, in vertebrates, and within the head segment in lower forms of animals. The brain varies in size and complexity from rudimentary ganglia (a group of nerve-cell bodies) in the central nervous systems of primitive worms to the large and complex human brain. As the central control organ of the body, the brain governs the functioning of the body's other organs. Sensory nerve cells feed external and internal information from all parts of the body to the brain. At least four medical subspecialties have a ...

  • The Brain Essay - 623 words
    The Brain Essay The human body is divided into many different parts called organs. An organ called the brain, is the center of the nervous system and it is the center of all voluntary and involuntary activities. It is also responsible for other complexities such as thought, language, and emotion. The brain weighs merely three pounds in an adult but it contains thousands of millions of nerve cells that make up the nervous system. For years scientists have been studying the enigmas of the brain and still today, there are many aspects of the brain that remain a mystery. In order to comprehend the brain, its necessary to understand the protection it has from injuries. Its also imperative to disc ...

  • The Effects Of Marijuana On The Brain - 470 words
    The Effects of Marijuana on the Brain Marijuana has been illegal for years because of the thought that it was a drug similar to cocaine, or heroin. Drugs such as cocaine and heroin affect the neurotransmitter dopamine. Dopamine is the neurotransmitter associated with extremely pleasurable sensations. If a drug interferes with its production and causes too much to be produced the result is extremely pleasurable and can lead to severe abuse and addiction. It has recently been proven that marijuana is not a drug that affects the production of dopamine. The average marijuana plant contains over 400 chemicals and when the plant is smoked or vaporized the heat produces many more. Receptors in the ...

    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 st ...
