Also the previable fetus has an EEG as flat as someone who is brain deadand it's fetal neural structure is about as sophisticated as that of a sea slug.
http://www.wired.com/wiredscience/20...lly-want-that/The tricky part comes when these definitions of life get applied at the beginning of life. The landmark 1973 case Roe v. Wade replaced an old marker of life — the “quickening” or first movements of the fetus — with one based on fetal viability, which typically occurs at about the 23d week.
This was a tactical move meant to provide a firmer marker for legal purposes. Law seeks clarity. Which is where a consciousness meter could be quite tempting to the courts — and discouraging to anti-abortion conservatives:
As leading neuroscientist Michael Gazzaniga, a member of President Bush’s Council on Bioethics, describes in his book The Ethical Brain, current neurology suggests that a fetus doesn’t possess enough neural structure to harbor consciousness
until about 26 weeks,] when it first seems to react to pain.
Before that, the fetal neural structure is about as sophisticated as that of a sea slug and its EEG as flat and unorganized as that of someone brain-dead.
The consciometer may not put the abortion issue to rest—given the deeply held religious and moral views on all sides, it’s hard to imagine that anything could.
But by adding a definitive neurophysiological marker to the historical and secular precedents allowing abortion in the first two-thirds of pregnancy, it may greatly buttress the status quo or even slightly push back the 23-week boundary.
