[h=1]Scientists restore activity in dead pig brains[/h]









Scientists restored some activity within the brains of pigs that had been slaughtered hours before, raising hopes for some medical advances and questions about the definition of death.

What do you think about this?

More power, Igor.
 

This topic could raise some serious discussions. Does brain activity equal life? Or, does the heart beating equal life? The heart beats because of signals or impulses from the brain. OTOH, if the brain does not receive oxygen through blood flow that is produced by the heart, it (the brain) will not survive.

Interesting, to say the least.
 
According the medical science, the brain dies when the heart stops and all brain activity stops.

Are the brain & mind synonymous?
 

Well, my personal opinion is that there is more to life than whether one's heart is beating or one has brain waves. Sure, those indicate that the body can still be animated or that the cells are still alive. But is that life? To extrapolate from the original experiment, fact that limited brain activity in this piece of meat we call our body could potentially be restored doesn't to me equal life.

Yeah, I know....my spirituality is showing! :whome:
 
So this brings me to the question that I have gone round and round about. I once read that a heartbeat in a fetus can be heard in about 7 weeks and some medical experts have said that life has begun.

Do you agree that life begins with a heartbeat? (This is NOT an abortion question. I haven’t lost my mind, yet.)

I agree.

Similar to the amazing Israeli experiments to create a heart using human cells and a 3D printer.

I have have been reading about this and find it amazing. Maybe in another 20-50 years heart disease will be like having appendicitis. Heart goes bad, the patient will schedule an appointment to get a new one and life goes on. Sort of like taking your car in for an oil change.

I don't see why the definition of "life" should have anything to do with a heartbeat. A sperm cell is alive. An ovum is alive, even before fertilization. A brand new embryo is alive.

Of course, "alive" does not mean a fully realized human being, with human rights. At the beginning, these live cells are potential human beings. And we'd probably better leave the discussion at that.

OK. I didn’t know that you were in charge of when discussions had to end. Sorry for my intrusion.

So, does that mean it would be a sin for a woman not to have babies for however long she is fertile? Is she a killer of life?
 
I don't believe in "sin," Olivia. And why would not having babies make anyone a "killer?" Sorry, I'm not following your reasoning.

The point I was trying to make is that "life" exists even before a heartbeat. Oldman asked whether life begins with a heartbeat. My response was an answer to that question.

And, since we're dancing around the point, let me clarify: I am very definitely pro-choice, and don't believe that a pre-viable fetus is a human being; it is a potential human being, just as a sperm and an egg are. When does it turn into a human being? My belief is that it's a gradual process, depending on many stages of development. A heartbeat is only one of those stages.
 
The way you said it, wasn't very clear. And it appeared, which you actually said, was that your opinion was the end of the discussion.
 
I don't know how I feel about his. Death had a finality to it. I was an RN. So I saw a lot of death. CPR pushed back that finality. I know this is merely some peripheral brain activity, but it is quite a bit after "death".
As afar as abortion is concerned. It doesn't matter when, but should a fetus be aborted. I think those, who do not favor abortion feel it is akin to murder. But these same people, do not have strong attachments to pregnant mothers , nor to the children when/ and after they are born. It's like not putting your money where your mouth is. But does the fact a women is pregnant require her to devote the next 18 years of her life to it. You can't legislate good mothering. I don't believe there is a National answer. I believe the answer lies with the one person, who can terminate a pregnancy-the mother. She has to bear the full weight of her decision, alone.

Was there a link with this? I don't see it if there was. I would love to read it.
