Nove su studije pokazale kako ljudi, za koje se mislilo da su u nepovratnoj "vegetativnoj" komi pokazuju znakove pune svijesti
New studies demonstrate how people thought to be in an irreversible “vegetative” state showed signs of full consciousness. by Rabbi Avi Shafran
Remember Terri Schiavo, the “vegetative” Florida woman who, as a result of her husband’s insistence and a court order (over her parents’ objections), was removed from life support and died in 2005?
“Vegetative” patients—people who, due to disease or accident, are unresponsive to stimuli—are considered by many to be less than truly alive.
Last year, though, a group of European scientists employed something called functional magnetic resonance imaging (fMRI), which shows cellular activity across brain regions, to demonstrate that four patients in a group of 54 diagnosed as vegetative were in fact hearing and thinking—and could actually communicate—answering yes-or-no questions about their lives—through mental effort.
Posljednjih godina, grupa evropskih znanstvenika je razvila sliku "funkcionalne magnetske rezonance" (fMRI) koja je pokazala staničnu aktivnost u području mozga, na taj se način pokazalo da 4 pacijenta ( iz grupe od 54 za koje je dijagnosticirano "vegetativno stanje") zapravo čuju, misle i mogu komunicirati , odgovarajući sa "da" ili "ne", na pitanja o njihovom životu- kroz mentalne napore
.
And now, the prestigious medical journal The Lancet has published a study demonstrating that three severely brain-injured people thought to be in an irreversible “vegetative” state showed signs of full consciousness when tested
with a relatively inexpensive, widely available method of measuring brain waves. The researchers used a portable electroencephalogram (EEG) machine, which picks up electrical brain activity in the brain’s cortex, or surface layer, through electrodes positioned on a person’s head. The research team gave 16 “vegetative” people simple instructions, to squeeze their right hands into a fist or wiggle their toes when they heard a beep. The tasks were repeated up to 200 times.
In healthy people processing those instructions, the EEG picked up a clear pattern in the premotor cortex, the area of the brain that plans and prepares movements; the electrical flare associated with the hand was distinct from that associated with the toes. Although the three supposedly vegetative people could not move their fingers or toes, their brains showed precisely the same electrical patterns...
(Halacha, to be sure, does not always insist that life be maintained; in some cases of seriously ill patients, even those with full brain function, it even forbids intercessions that will prolong suffering. But Judaism considers life precious, indeed holy, even when its “quality” is severely diminished. And so, halacha does not permit any action that might hasten the demise of a person in extremis. And, needless to say, it forbids removal of vital organs from a patient not deemed by halacha to be deceased ...
