Brain death

A prion is a infectious protein agent and the specific name of prion in BSE is PrP scrapie(PrPSc). The normal protein that is being acted upon by the protein is called cellular prion protein(PrPc). Prions are a problem because they are an abnormal form of a normal protein that is misfolded without an immune response. The strings of amino acids are put together to make proteins inside cell. Then they are then pushed together and folded into a framework letting them function properly. These prion…

similarities to waking states, including rapid, low-voltage desynchronized brain waves. Electrical and chemical activity regulating this phase seems to originate in the brain stem and is characterized most notably by an abundance of the neurotransmitter acetylcholine, combined with a nearly complete absence of monoamine neurotransmitters histamine, serotonin, and norepinephrine. The right and left hemispheres of the brain are more coherent in…

affected by it. Alzheimer's is the most common form of dementia, a severe brain disorder that causes major memory loss and other serious cognitive changes. With Alzheimer's, nerve cells in the brain being to die which makes it difficult to do simple tasks others take for granted, like how remember, learn, or create. Alzheimer's leads to nerve cell death and tissue loss throughout the whole brain and over time the brain shrinks, affecting pretty much all of its functions. It is a irreversible…

Scientist discovered cocaine promotes change in the brain through other neurotransmitters such as serotonin, gamma-amino butyric acid (GABA), norepinephrine and glutamate. An idea to creating medicine to act as dopamine D3 receptor pharmacotherapeutic associated with cognitive, emotional and endocrine functions…

sclerosis (MS) is a muscular disease that affects the central nervous system (CNS) which consists of the brain and the spinal cord. This disease was discovered by Dr. Jean Martin Charcot. Eventually, improvements in microscopes helped doctors in the search of understanding the disease. In 1916, a Scottish doctor named James Dawson was able to clearly describe the inflammation after viewing the brain cells of a patient with multiple sclerosis through a microscope. Over the years, numerous…

continued deterioration of the cells inside the brain, which causes a considerable loss of memory, and eventually causes a severe interference in everyday activities.…

body. The CNS includes the brain and spinal cord. The digestive system is affected by Alzheimer 's, this system includes; the mouth with salivary glands and teeth, pharynx, esophagus, stomach, small intestines, large intestines, rectum, and anus. The Urinary system includes the kidneys, ureter, urinary bladder, and the urethra. The neuromuscular system is affected as the disease progresses, this includes the nerves and muscles of the body. Due to the effects of the brain 's blood cells the…

thinking or trouble remembering could be normal with aging but major changes in the brain, critical memory loss and confusion could be a sign that there are cells failing or plaque building up on the brain. There are two kinds of unusual formations called plaques and tangles which are responsible for damaging and killing cells in the brain. Alzheimer’s is an irreversible and debilitating disease that affects the human brain by destroying memory and restricting the victim from carrying out the…

considerable impact on brain function. Modern forms of sugar do not always have a positive impact on the brain. Different kinds of sugar impact the brain and body in very different ways. Negative effects of sugar discussed in this paper refer to added sugar. Natural sugar found in whole foods that is not added during processing is considered “good sugar” and not responsible for the negative effects mentioned. Although sugar may seem like the perfect substance for the brain, diverse structures of…

's Changes the Brain,” “Alzheimer’s disease leads to nerve cell death and tissue loss throughout the brain. Over time, the brain shrinks dramatically, affecting all of its functions…the cortex shrivels up, damaging areas involved in thinking, planning and remembering. Shrinkage is especially severe in the hippocampus, an area of the cortex that plays a key role in formation of new memories. Ventricles (fluid-filled spaces within the brain) grow larger” (“Alzheimer 's Changes the Brain”).…
