stion 11 2 points Save An The legal definition of death appears to be on the verge of changing Which of the following are prompting this change? O The higher portions of the brain often die sooner than the lower portions Which of the following statements represent assumptions, rather than inferences or observations, that Personality and intelligence are located in the higher cortical part of the brain The cessation of electrical activity in part of the brain indicates that a part of the brain can no longer function When higher cortical function is lost, a person is no longer a human being Most physicians define brain death as the death of both higher cortical functions and the lower brain stem functions

Explanation / Answer

Defining death was simpler 24 years ago, than it is today. Determining when death has occurred is difficult, as cessation of life functions is often not simultaneous across organ systems.When consciousness ceases, a living organism can be said to have died. But there are many organisms which are alive but probably not conscious. The end of certain biological functions, such as breathing and blood pressure and the rigidity of the body were clear signs of death. Death is now more complex. Determining when death has occurred is difficult, as cessation of life functions is often not simultaneous across organ systems.When consciousness ceases, a living organism can be said to have died. But there are many organisms which are alive but probably not conscious. The neurological definition of death states that a person is dead when all electrical activity of the brain has ceased for a specific period of time. It must include the death of both higher cortical functions as well the lower brain stem functions. It is assumed that an end of electrical activity indicates the end of consciousness.
