Extract of sample "Brain Death"

Download file to see previous pages ‘Brain-death’ definition of human death has engendered several questions on what constitutes human life. Brain-death in this context refers to “the cessation of brain activity and function as measured by specific tests” (Blank, 193). In 1968, the ‘Harvard Criteria’ for brain-death was issued, which was centered on the lack of responses, movements, and reflexes. The unavoidable conjecture that this definition of brain-death was linked to the facilitation of organ transplants cast an aspersion on the ethics of this definition. The present standard accepted definition of death, according to the ‘Uniform Definition of Death Act,’ in 1981, encompasses the “irreversible cessation” of either cardiorespiratory functions or all brain functions. This whole-brain definition of death remains contentious because, in some cases, circulation and respiration, which are controlled by the brain stem, can continue while consciousness, which is controlled by the cerebral cortex, can be permanently lost. This has raised the issue of a “cerebral death definition” (Blank, 196), which equates human life with consciousness. Region-specific brain imaging techniques are of significance here. This definition directly impacts Persistent Vegetative State and Alzheimer’s patients. Advance directives and prior donor consent assume relevance in this context. Blank concludes by stating that the definition of death is the subject of public policy, with social, cultural, and religious ramifications and needs to be debated further.
Brain death refers to the irreversible cessation of brain function. In 1968, a Harvard Medical School Committee formulated the ‘Harvard Criteria’ for defining brain death which has become the accepted standard criteria in most of the developed world. The following were identified as the criteria for brain death: unreceptive or unresponsiveness, lack of spontaneous movement or breathing, and lack of reflexes. ...Download file to see next pagesRead More

Brain Death Scenario

... with a wholesome and informed approach. Purpose of the paper The purpose of this paper is to discuss the ethical, legal and medical implications that surround brain death, and to divulge on how physicians should handle brain death. a) Ethical Issues Surrounding the Situation One of the ethical issues is that of organ donation or harvesting. The law consents that organs can be harvested from patients who are brain dead, provided that all provisions specified within the law are observed. This is because, brain death can lead to legal death despite the patient’s heartbeats and respiration being sustained through mechanical ventilation, thereby making the sustenance of vital organs for organ transplantation very possible. In this case...

Brain Plasticity

... have established in the recent years, along with gradual acceptability that new neuronal cell birth takes place from time to time in the fully developed brain also. The fact of irreversible brain death has been left behind now. There is now a lot of active work going on this research criterion. These young neuron cells bud from stem cells present in basal ganglia, hippocampus and frontal lobes, and develop into full mature neurons having axonal body and dendritis. These new budded neurons serve the purpose of filling the spaces of brain areas that lack the needed neurons. These new neurons acquire locomotive properties in the brain and modify themselves to fulfill the function of the brain when and where required. Functional Compensatory...

..., responsiveness and alertness. There are five unconscious states that result from the traumatic brain injury. These five states are: Persistent vegetative condition Brain death Locked-in syndrome Stupor Coma In our case, the patient was in a stupor case (Rider, 2009, 74). This gives a clear impression that he was in a position where he was not able to respond but was able to be aroused by a stimulus that is strong. In this case, it is clear that the patient was brought in but was not in a position to do anything because he could not respond until when aroused (Profetto-McGrath and Raymond_Seniuk, 2012, 34). We implemented various medical strategies to make sure that the patient came back to his normal state. It took a while for us to do so...

Brain Cancer

The growth of cancer cells in the brain tissue is termed as brain cancer. A tumor or mass of cancer tissue is formed by the cancer cells. These tumors affect the functions of the brain, such as memory, muscle control and memory. Tumors are classified as malignant, when they are comprised of cancer cells. On the other hand, tumors consisting of non – cancerous cells are termed as benign (Davis & Stoppler, 2013). Furthermore, cancer cells resulting from brain tissue are termed primary brain tumors; whereas the cancer cells that spread to the brain from other sites in the body are termed as metastatic brain tumors. It has been projected, by the available statistics that brain cancer could develop in approximately 22,000 individuals...

Split Brain (Brain Area Functions)

...Split Brain Split Brain The corpus callosum is a part of the human brain which is involved in the integration of the left and the right hemispheres of the brain. It is made up of many fibers which tend to link the two regions of the brain. The corpus callosum performs many important functions. It carries out the function of sending the information from one hemisphere of the brain to the other one which will be responsible for the carrying out of that activity. There are certain activities that can be done by both the hemispheres and it is the function of the corpus callosum to assign any one the hemispheres for that activity. It also tends to create a coordination of the two hemispheres for activities that need the combined function...

Brain vs Left Brain Learning

... Right Brain vs. Left Brain Learning Introduction: The brain is the most complex organ in a human body and various aspects of its function are still a topic of research and constant debate. However, many authorities agree that two hemispheres of the brain are capable of thinking in separate directions. The recent work of Roger Sperry in his research of “Split Brain Theory” has fascinated many researchers around the world. He received a Noble prize for his work in 1981. In his Nobel speech, he mentioned that the same individual is capable of exhibiting two distinct forms of mental approach and strategy, just like two different people depending on whether Right or Left hemisphere is in use (Duggan). A fibrous tissue called Corpus Callosum...

Brain

...Psychology What are two kinds of evidence that consciousness depends on a functioning brain? To start with, damage to the alerting areas of the brain, the brain stem and the midbrain, most likely can result to loss of consciousness. The first evidence is that consciousness cannot exist without the cortex working accordingly. Without this part, it would not be possible to comprehend speech, plan, move, solve problems, or express emotions. All these are aspects of consciousness. Second evidence is the brain stem. The hypothalamus is responsible for the sleep cycle; therefore, the suprachiasmatic nucleus controls the preoptic nucleus that induces sleep. By inhibiting the reticular activating system in the brain stem, the preoptic nucleus...

Brain Imaging

...Brain Imaging Brain Imaging How do the brains of children and adults differ with regard to energy consumption?  Energy consumption of the brain in children is higher than that of adults because the brain gobbles more glucose when the body experiences slow growth. At 4 years, the brain burns glucose at a rate of 66 percent of what the whole body uses at rest because high fraction of the body’s resources are halted during brain development (Shulman 2013). On the other hand, the brain of adults do not consume a lot of energy since the body uses most of the energy to enhance higher body growth since the brain is fully developed during adulthood. 2. In what ways do brain waves change as a person falls asleep? Sleep is always characterized...

Brain rules

...Brain rules November 11, Brain rules Summary Rule number one s that exercise boosts brainpower. Empirical data supports this and shows that exercise promote executive function, spatial tasks, reflexes, and quantitative potentials. This is because exercise increases oxygen supply to the brain towards mental sharpness and increased number of neurons. Rule two states that the brain evolved too. This is because of its ability to have survived the environment and to have ruled the world. Scientists also argue that walking upright made the brain bigger and its operations more efficient, a change that defines evolution. Every brain is wired differently, according to rule three. Different fine routs that develop from people’s experiences exist...
