Brain death

seizures as the sudden simultaneous firing of cells in a particular part of the brain. This is shown as high amplitude/high frequency EEG waves; and could cause physical convulsions of the body. The effect to the brain is a lot more wide spread with consequences that occur both during and for some time after the seizure activity. A paper by Fernandes, Dube, Boyet, Marescaux and Nehlig (1999) explained that knowing how the brain would react to an epileptic event after a period of asphyxia at one…

is a disease, where your brain is functioning normal, but other parts of the body are unfunctional. Now the brain is not functioning how it normally should, but the body is functioning how it should be. Chronic Traumatic Encephalopathy (CTE), a disease that is affecting the brain little by little, but does not change a person’s physical function. Both ALS and CTE start from a simple hit to the head,which causes one to have a concussions. Concussions occur when the brain is being hit with…

disorder of the brain that affects individuals of all ages worldwide. It is one of the world’s oldest documented disorder. It is described as having multiple unprovoked seizures. Seizures are short occurrences of involuntary movement that may include a part of the body (partial) or the entire body (generalized) and are sometimes accompanied by loss of consciousness and control of bowel or bladder function. Seizures are an outcome of excessive electrical discharges in a cluster of brain cells.…

Lou Gehrig’s disease is also known as Amyotrophic Lateral Sclerosis (ALS). ALS is a disease that affects the nerve cells in the brain and the spinal cord. It is a progressive neurodegenerative disease, this eventually leads to death. The patients lose the ability for the brain to control muscle movement. Since most motor neurons are lost, the patients may eventually become completely paralyzed. Motor neurons can no longer send signals or impulses to the muscle fiber resulting in no muscle…

notorious ways the typical teenager thinks. Recent studies have shown that there is a scientific reason behind this infamous behavior. Scientists used to believe that the human brain develops mostly during early childhood. However, MRI scans have shown that it doesn't stop developing until the mid 20’s. The teenage brain, though it’s not fully developed, comes with some positive quirks: it’s sensitive to rewards and to its environment, which makes the teen themself so sensitive. This heightened…

my second DNA sequence. Alpha-synuclein’s function in a healthy brain is unknown , but it is known that this protein causes Parkinson’s disease or PD. Parkinson’s disease is a disorder of the nervous system which causes one to not be able to control their normal movements. The way this works is that there is a malfunction and death of neurons in the brain , specifically substantia nigra, which is the movement control center in the brain. These dying neurons produce dopamine and as time goes on…

Brain scans are an important tool used by doctors to allow them to have a look at what might be doing on inside the brain giving a patient discomfort. Brain scans have a wide range of potential that has yet to be utilized by doctors. This type of imagery is only used when symptoms occur and once the issues have already arose. If a child received a brain scan as a baseline scan and then continued to receive a brain scan once every five years during their lifetime. It would be beneficial to both…

The neck is a complex part of the human anatomy. In addition to supporting the head, it serves as a conduit of blood flow and nerve impulses between the brain and the rest of the body. In spite of this essential function, it's highly vulnerable to injury, particularly the carotid and vertebral arteries. The carotid artery is close to the surface of the neck and can be injured by blunt trauma. Both the carotid and vertebral arteries can be injured by rapid or violent motions of the neck or when…

coping brain, are Thinking, Emotional, and Reptilian. Those are to be the main subjects of this essay. The human brain is the most complex thing we know of, but yet we know very little about it. However, we do know that in times of stress or worry, each and every individual person has a unique way to cope with it. But the three parts of the brain, Thinking, Emotional, and Reptilian, are the base for all of the different ways we cope. Thinking or the neocortex, is the part of the brain…

and improvements that were made in the 21st century for the betterment of people’s health. For example, before technology, one of the only ways to investigate brain function was to open up the skull and physically probe into the brain. However the proper technology is now available to accurately localize essentially every part of the brain without opening the skull. “By following the changes in blood flow and chemical activity that accompany neural activity, it is possible to map the areas…
