You want evidence that the neo-cortex is required to process sensory functions? There's a whole mountain of it. Do you also want evidence that anencephalics are blind, dumb, deaf, unable to feel emotions or sensations? There's a whole mountain of evidence for that too. The neo-cortex doesn't fully form until the third trimester. So where are you going with this?


This says 6.5 WEEKS. I knew 6.5 months sounded totally wrong.

I found one paper that refers to a rudimentary neocortex being present at 6.5 weeks: Reactive Invagination of the Neuroepithelium in the Rudiments of the Neocortex, Tectum of the Midbrain, and Retina of the Eye in Humans at Different Stages of Development, E. B. Smirnov, V. F. Puchkov and V. A. Otellin, Neuroscience and Behavioral Physiology Vol. 31 No. 6, Nov. 2001

wtf? Last time I checked fetuses hardly even have a brain stem at 7 weeks. So if anything there would be a rudimentary brain stem.
Quote:
The human brainstem is fashioned around the 7th week of gestation and matures in a caudal to rostral arc thereby forming the medulla, pons, and midbrain. The medulla mediates arousal, breathing, heart rate, and gross movement of the body and head, and medullary functions appear prior to those of the pons which precede those of the midbrain. Hence, by the 9th gestational week the fetus will display spontaneous movements, one week later takes its first breath

i find the distinction between having senses and breaking when you get hit by a hammer kinda hard could someone please explain in detail where this distinction atualy lies?

Rather, although capable of learning, the increasingly complex behaviors demonstrated by the fetus and neonate, including head turning, eye movements, startle reactions, crying, screaming, and rudimentary smiling, are probably best described as brainstem reflexes.


Hmmm. I'm sure people said the same about animals when we didn't recognize they had any rights. They're basically saying 'even though the unborn show all the signs of being conscious, they actually aren't'.

What is rudimentary smiling anyways? lmao

Darling, you apparently don't understand enough biology to understand what that paper is saying. Invagination of the neuroepithelium means that the proto neural cord is forming into what will, in several months, be a neocortex.

there are also some good nerulation videos on youtube.

I got a new solution to the abortion debate! Fuzzy logic.

In classical set theory, an element x either belongs to a set or does not. In fuzzy set theory we can talk about the degrees by which something belongs to a set.

I think that no rational being would ever come up with an argument against the notion that personhood certainly and 100% surely does NOT begin at conception. It is simply an insult to the intelligence of anyone to believe that the single cell formed by an ovule and a sperm should somehow gain a person's rights. In that case, we can agree that at time t=0 seconds after conception, the thing is certainly not a person. Thus the [i]degree] of membership of a being to the person set at time t=0 is 0.00.

Thus we have U_person(t=0) = 0.00

It is a valid standard with full consensus that it is illegal to kill newborn babies. Thus we can all agree that when t=~ 9 months we can be certain that the fetus is a person with full set of rights.

U_person( t = 9 months ) = 1.00.

Now, here is where fuzzy logic comes into place, what to do about intermediary stages? We know that at 8 months a premature baby can still live with some support. At 7 months it is also true, but with a smaller chance of that happening. Let's say that at 7 months, a fetus is 75% times a person.

U_person( t = 7 months ) = 0.75.

We can now make a formula based on time : if (t >= 7 months and t <= 8 months ) the degree of membership is: 0.25 * (8 - t)/ 1.0 + 0.75 .

if (t >= 8.0 ) degree of membership = 1.0


Now, we know that at 6.5 months there are finally Thalamic connections to the brain. This means that senses are not even wired until that time. Just senses is by no means the same thing as a person. But we can consider it to be around midways, so let's say 40%.

if (t >= 6.5 months and t <= 7.0) degree of membership = 0.35 * (t - 6.5)/0.5 + 0.40
this way, at t = 6.5 months, the degree is 0.40 , yet at time t = 7.0 months, the degree is 0.75.

At sixth week, or 1.5 months, extremities begin to appear. It is very hard to consider a thing remotely close to a person before it even has differentiated members. But it is definitely closer to human than a just-fertilized egg. So, let us say it is 5% a person. We have:

if (t >= 1.5 months and t <= 6.5) degree of membership = 0.35 * (t - 1.5)/4.5 + 0.05

And later, we add:

if (t >= 0 and t <= 1.5) degree of membership = 0.05 * t/1.5

So, let's say what happens to a woman who aborts at the 3rd week (t = 0.05):

The degree of membership of the embryo is: 0.0016666666666666668 or 0.17% . So it was 0.17% a person

For a pregnancy that ends after 8 weeks, or 2 months, the degree is 0.088 or 8%. This would mean that abortion after 8 weeks is 8% of manslaughter. (not murder, it is not the same).

Can't argue with math. If I had time, I would make a graph showing how the function looks. If anyone can help would be nice.

Edit: * Do notice that at 7 months, things change and it is now 75% of manslaughter. The best conclusion to take is that the best to avoid killing something with a large percentage of personhood is to practice abortion as quickly as possible. It is only moral to be honest to anyone going through unwanted pregnancy and tell them that the best to avoid suffering is to make the abortion as quickly as possible. For this same reason, I think it is inhumane to push for laws that delay abortion for people that have already decided it.


Hmmm... I think your viewpoint has been tainted. Stop debating in the box. Math really doesn't have anything to do with it. Any reproductive material that exists or survives in its natural habitat and has the ability to become a person in a given environment and set of circumstances should exist in a special protected class and cannot be killed. Personhood begins at conception. The outlook of the life has nothing to do with it either. Advances in medical tech can occur at any time and gene therapy will eventually be able to fix anything. Further, life and potential life must be preserved. We shouldn't have a hand in the probability of life happening. Condoms are fine however given that the source of the reproductive cells still exists. A person has an intrinsic right to choose to have children. Hormonal birth control for women is ok as long as they can figure out how to prevent it from interfering with the development of a conceived embryo. Once that little quirk gets worked out we're fine. Substances that can affect fertility and the health of one's children other than by their express choice to swallow the pill or get the shot should be banned altogether. IT should be mandatory that all individuals have a specimen of their reproductive cells frozen when said cells become mature.

Rather than debating the argument I think it is a much better idea to simply develop artificial uteri and allow women to move an unwanted pregnancy to an artificial uterus or put the embryo on ice for adoption. Anything else would be 100% murder, no exceptions, no excuses for murder and/or genocide.

Each sperm has to have something equivalent to a nerve center to wag it's tail, so if that part winds up in an ova, it has a brain. Issue solved and the age old myth of man having a brain in his pants is busted because he in fact has many!

Apparently the fact that it is in the process of turning into one shouldn't matter, and apparently it's fine to interfere with that process just because someone was stupid enough to conceive a child that they didn't want. :roll:

If no one is ever made to take responsibility for their own stupidity, people are just going to continue to get even more stupid.


A lot of times it isn't stupidity, it's failure of the birth control. Also, why should a woman deal with having a baby inside her body for forty weeks and putting her own health at risk because of a few minutes of a mistake? There is a simple and safe procedure than she can have done, which will remove it. Should pregnancy be punishment for the woman for having sex? Or revenge because she got laid??


If she isn't prepared to take the risk of getting pregnant then she shouldn't be having sex in the first place. Yes, it is stupidity. Yes, it is her responsibility. No, the fact that she "made a mistake" does not change any of these facts, nor should it give her the right to end the life of another person.

Intentionally performing the reproductive act with no regard for the potential consequences is her own fault. Accidental failure of contraception is no excuse, everyone knows that is a risk of having sex, and anyone unprepared to take the responsibilities of reproducing shouldn't be doing it at all.

A person's life is more important than a person looking for cheap thrills and trying to ignore the responsibilities that come with them. No excuse you make in the name of irresponsibility will ever change the fact that that is what it is.


but no person has a right to another persons body and fact is that at conception it isnt a person, it is physically impossible.

so you want to dehumanize the mother, with consequences to follow,
that might lead to her feeling animosity towards her child, with consequences to follow,
so in the end you would rather see a child suffer than not exist and that is pure evil.


You would rather end the possibility of someone's life than have a woman raise a child or give a child up for an adoption. What part of a woman having a baby is dehumanizing... now if you were to tie her tubes without giving her an on/off switch and some way to actuate it, that would dehumanize her. If you were to take a life that came from her, that insults her dignity as a person. Her children have a fundamental right to exist.

Consenting to sex is not consenting to pregnancy and childbirth. Sorry, it doesn't work like that. Even before there were birth control pills, sterilization, and legal abortion, there were herbs that women could use to cause an early miscarriage. There have always been ways that women could avoid giving birth when they wanted or needed to. The mothers body is here first, so it's first come, first serve.

Just because you, or a group of like minded people, want to punish a woman for having sex does not mean that it's right to do so, or that you can.


The problem with that argument isn't that a woman is being punished for having sex, it is that you view having a child as a punishment which it is not. So when you stop seeing children as a punishment, what are they?

Sex makes kids, everyone old enough to have sex knows that. Maybe we should stop teaching the stork... That silly animal seems to me to be behind this misunderstanding.

If abortion was already illegal, or never was and we just kept the argument going to keep people from becoming basement abortionists, how many of you would feel pretty embarrassed right now for saying it's ok to kill someone? Show of hands!

Sperm moves and has a functioning component that allows it to negotiate with its environment and control its functions. Ova inherits what the sperm has... ergo, the basis for the brain in an embryo begins at conception. Why make pain part of it...

For Christ's sake, people, please stop making up biology when you don't know what the hell you're talking about! A SPERM IS A SINGLE CELL. A NERVOUS SYSTEM = TRILLIONS OF CELLS. Just because something can move, does not mean that it can think or feel.
edit: read up on chemotaxis, webcam. It's purely mechanical. There are a lot of mysteries in biology, and this is NOT one of them.
As for '...the ovum inherits...' I'm really hoping that that was just a poor choice of words on your part and not something reflecting an actual belief on what happens during fertilization (which is NOT, by the way, the same thing as conception).

It's not so much about raising the child and/or giving it up for adoption, it's about being forced to contribute one's body as a life-support system to another organism during pregnancy and childbirth. Also: a zef is not a child.

Pregnancy and childbirth are not fun, for one thing, nor is raising a kid (a child is not a puppy), and for another most pro-lifers (including at least one who has already posted on this thread) do speak about pregnancy as an appropriate punishment for any woman, single or married, who is such a slut* that she dares to have sex without their permission.
*Conservatives other than Rush Limbaugh rarely use this word, but it's almost always present in the subtext.

I didn't say nervous system, I said nerve center equivalent for lack of a better term. Please try to understand my cave paintings if you will. I'm simply referring to the fact that in order to demonstrate locomotion and seek an ova, a sperm can use it's function to accomplish something ("gettin it in" to the egg). So assuming that the tail functions electronically or has physical properties that allow it use elemental properties in the pursuit of a goal is has a simple 'system' of some sort that communicates to its different parts in much the same way that my brain tells my fingers to type. So if it has locomotion, it has a 'brain,' it just happens to be a very simple one that is waiting to develop.

Am I thinking when I move my finger if I am not typing something? Well, there is certainly some form of brain activity in some part of my brain or another... I would argue that the current definitions are very limited and very limiting in general. The less about the conventions that I am taught, the more that I seem to know. The conventions are flawed and can't fully explain anything. Thinking may be a greater range than what is described in a book by conventional science. Isn't survival a feeling? Have you ever felt it?

Darling, No. No.
I said it before: google chemotaxis. There is no 'nerve center,' no nervous system, no nerves. A single neuron is usually bigger than a sperm cell.

Seriously, I'm not being arrogant here, just honest: this is below Biology 101. You do not understand what you're talking about, so stop embarassing yourself and telling yourself that 'Of course I understand it, how hard can it be?!'

Here, I'll even do it for you. Some basics:
http://en.wikipedia.org/wiki/Chemotaxis
