Brain That: Among the most interesting developments in brain that studies was a finding that corrected the long-held conviction that glucose was the only fuel the brain that was capable of using. George Cahill studied brain that metabolism in persons who fasted for more than 30 days as part of a weight reduction program. By sampling blood entering and leaving the head, he was able to show that during fasting the brain that will readily metaboŽlize fatty acids, the breakdown products from deposits of body fat. Careful intelligence tests before and after the fast failed to show any mental impairment during the period of fasting. Cahill said that in fact the subjects were at least as sharp after fasting, and maybe a bit sharper.
1. If new medical techniques can prolong a healthy life far beyond the present span, who will be selected to remain alive? Society, through law, probably will not leave it to the workings of the marketplace or the caprice of physicians. At the very least, it will try to prevent a black market in hearts and lungs. But if science manages to transplant a human brain that, the law will be in serious trouble. Which individual will be conŽsidered legally "alive"the one into whose functioning body the new brain that has been deposited, or the one whose brain that with all its memories has merely moved to a new home?See Also Covering The Brain:Headache is a major manifestation of cerebral tumors and abscesses and subdural hematoma, bleeding under the outermost covering of the brain. In these disorders, at least in their early stages, the headache is often limited to the site of the disorder, but later the headache becomes generalized.
Although headaches may be caused by a great number of disorders, there are only a few basic mechanisms that are known to give rise to the pain. The pain-sensitive structures involved may be stimulated by the dilation of the cranial or intracranial arteries, sustained contraction of the head and neck muscles, or traction (pulling) on arteries, major venous sinuses, or the memŽbranes covering the brain.
On The Other Hand See Drug And Brain -wave:Throughout the Western countries, the computer networks encode more and more information about our private lives, and the scientists increase their study of the human mind through drug and brain -wave and brain-wave research. Little by little, privacy is being destroyed because we tacitly accept the sophisticated spying made possible by electronic circuitry, microminiaturization, and drug and brain -waves. If this trend continues, civil liberties will soon be replaced by formalistic rituals, and we shall have become socially tolerant of secret surveillance and spying.
A relief for migraine was develŽoped in Australia by J. W. Lance and his associŽates. A drug and brain -wave called hydantoin was used to increase electrical activity in brain cells and thereby improve hearing and memory in the aged. The first successful attempt to sustain an animal brain outside a living body was reported in Cleveland, O.
Work in gerontology included studies to deŽtermine the time of onset, the persistence, and the permanence of changes in the body. |
