Scientist Says Mind Continues After Brain Dies.

June 29, 2001 7:56 AM

Scientist Says Mind Continues After Brain Dies. This articles raises an interesting new theory on how the mind works, suggesting that perhaps a person's consciousness exists independent of the brain, with the brain acting as a sort of receiver of thoughts. Interesting and scary.

That is very cool. I'm of course extremely skeptical that anyone could ever prove the existence of a soul through earthly research, but still--that is some interesting reading. Especially the part about the kid who was 2 1/2 years old...

I'd like it if they showed more about the patient's beliefs going into the temporary death. Was there any correlation about the likelihood of NDE among those who believed in things like souls and stuff?

Also, what does it mean to be "clinically dead" in this case? When you die, does everything stop working at once, or do some cells tick on until they run out of supplies? Is it like, that little green line goes flat and the intermittent beep turns into one long tone like the movies, but my muscles are still using ATP and voltage-gated ion channels are still opening and stuff?

Sounds like 5 cent baloney to me, these 'test subjects' have clear religious views and even if they had nothing happen to them to them they're 99% prone to making it up. You'd be surprised how sad and pathetic a lot of these people are, priests can go about their entire lives stabbing their hands to show they're blessed. It's downright sick. If they did then certainly there's much more we can learn about the human brain. Most of the nde stuff has been proven to be bunk.

and, like, no one thought that these guys merely imagined that they'd communicated with people after their brain stopped functioning? that, perhaps, they thought they should have done these things and are therefore convinced they did? or perhaps they (for example the so-called "pagan") did not want to just fuck with the doctors conducting this study?

are these guys idiots, or merely gullible?

This study makes an invalid assumption: That if someone remembers something then it must have actually happened.

oh, and the kid's the best.

When they asked what the balloon was he said, 'When you die you see a bright light and you are connected to a cord.' He wasn't even 3 when had the experience,'' Parnia said.

no one told him to say that! i swear!

My mom had an NDE. She was in a near-fatal car accident and she was declared legally dead in the ambulance. She said she saw a bright light and felt really peaceful, and then she heard a voice say that she had the choice whether to live or to die. She said the light was so beautiful and she felt so at peace that her instinct was to go towards it, but she still remembered she had us kids, very young at the time, and she decided to live.
My mom's a little nutty anyway, a very spiritual ex-hippy type person. I don't really believe in this stuff myself, but one thing I can say is that she isn't making it up. She really and truly believes this happened to her. Steven's right though, that doesn't make it real.

[From the link, emphases mine] During the initial study, Parnia said, 63 heart attack patients who were deemed clinically dead but were later revived were interviewed within a week of their experiences.

Of those, 56 said they had no recollection of the time they were unconscious and seven reported having memories.

Hmmmmm. I think I'm having a Near-Nonissue Experience.

The word "scientist" doesn't describe someone who would say this:

"The brain itself is made up of cells, like all the body's organs, and is not really capable of producing the subjective phenomenon of thought that people have, he said."

I'm not saying he's wrong... just that he's clearly either not trained in the scientific method, or he didn't understand that training. What's the evidence supporting that statement? What a crock!

Yah, seriously, its not interesting or scary -- maybe just a little sad.

Religion is a fine thing, but attempts to nail it down with pseudo-science bullshit are just pathetic.

If I wake you up, and you tell me about a dream, and I say "exactly what time did that dream start and end?" you arent going to have a damn clue -- why would a pre-death hallucination be any different? Maybe they experienced this feeling before they died, brought on by the drugs and adrenaline. Is dissassociation so uncommon when the body is stressed?

Bleh.

*cough* If you're going to accept science's fundamental axioms (and most of us do), Daniel Dennett's Consciousness Explained will tell you why consciousness without the brain is impossible. Cartesian dualism, which all of this (and most of us) typically assume is logically self-contradictory. Sorry folks. These people were probably projecting memories of experiences that occured while their brain was functioning onto the time when it was not. (Or do you think that your perception of time is always accurate? Sorry, chuckles.) Dennett's "Multiple Drafts" model describes how this is possible. (The book is an absolute must for any psychologist or philosopher interested in the opposite field.)

Another thing: when people take dissociatives(pcp, ketamine, dextromethorphan), don't they sometimes report similar experiences? I wonder if any of the things happening to the brain under these stresses are similar to the state that these drugs bring about and if there is some tendency of the brain, in the absence or presence of some factor or factors, to generate this "floating outside the body, looking back" sense-experience-collection.

Tweebiscuit - just to play devil's advocate, have you ever read McGinn's essay, "Can we solve the mind-body problem?" He tries to argue from something that looks like science for a sort of pseudo-supernatural attitude towards the mind. I don't think it's a very good essay, but since you brought up Dennett, I figured I'd bring up one guy who, if right, would give the "we don't understand how the mind arises from the brain" guy some working room.

there was once a time when the concepts of bacteria and germs were considered ludicrous.

I'm by no means a religious person, but I definitely believe that there is more to a person than some random matrix of chemicals. if we just sit for a while and not discount something just because it's incongruous with our mostly accepted orders of thought, maybe we can find out for sure.

Am I the only one that's curious to know how they define brain activity? I mean, even after all the brain activity we typically measure stops, the brain itself is still there. We don't have a very clear idea of how consciousness arises from the activity of the brain. I would assume it's perfectly possible that, after it has stopped functioning properly, the brain is still changing in some way that would manifest itself by either (1) giving people the experiences described above or (2) forming memories of the experiences described above.

Which is not to say I'm absolutely convinced of materialism, just that these observations don't even seem like the sort of evidence you'd look for if you wanted to disprove it. As for Dennet, for all he seems to adore science, he's still very much a philosopher, and I've not seen any evidence that he can make a convincing scientific argument for anything.

While I would like to believe this study, I recently read about another discovery that could explain new and/or false memories being created.

Essentially, memories are recalled electrically, but stored chemically. So even if they are not recording any brain activity, that is electrically activity. That wouldn't stop new memories from being created chemically.

One more thing ... John Edward is a punk.

mcsweetie, I don't think anyone's saying people are just a random combination of chemicals. even if we are nothing more than chemicals and electricity, it's a very specific set, and that's what allows us to know anything about the physical nature of our brains (and other contsituent parts) at all. granted, a lot of scientists and doctors and pharmaceutical companies like to pretend they know more about the way neurotransmitters work than they actually do, and I agree with you that much of neuroscience is far too reductionist to be useful, but just because someone thinks the idea of a soul completely separate from the physical brain is "ludicrous" doesn't mean they think the brain is just a bunch of discrete chemicals and cells and stuff. and even if it is just a bunch of things that we understand individually, that doesn't mean we think we understand the combination.

Wow! Thanks, quirked, that's exactly the sort of suggestion I was hoping for, without knowing enough about the brain to state it more precisely. In thanks, I offer:

One more thing ... John Edward is a punk.

John Edward is a punk,
Sam Parnia's a runt,
They both went out and offered evidence for dualism
And oh I don't know why,
Oh I don't know,
Perhaps they'll die, oh yeah, perhaps they'll die.

Second verse, same as the first:
John Edward is a punk,
Sam Parnia's a runt,
They both went out and offered evidence for dualism
And oh I don't know why,
Oh I don't know,
Perhaps they'll die, oh yeah, perhaps they'll die.

Third verse, different from the first:
John Edward is a punk,
Sam Parnia's a runt,
And Sam confused electrical activity with life...
And oh I don't know why,
Oh I don't know,
Perhaps they'll die, oh yeah, perhaps they'll die.

I once passed out in the middle of a workout - pressing too hard, stood up too fast, hit the ground too hard. The entire episode lasted less than five seconds, but I had a very vivid dream during that time that seemed to go on for several minutes. Malphigian's comment above about not being able to trust "dream time" is right. The subjects entire "remembered dream" could have occurred in the brief second before they lost brain activity or in the brief second after they regained it. The story is interesting, but doesn't provide any proof either way about the existence, or lack their of, of a nonmaterial source for consciousness.

The kid's "you see a bright light and are tied to a cord" sounds to me like a birth memory.

The elusiveness of time while dreaming is well-established. I once saw a show on "alien encounters" in which one "abductee" explained that "the aliens must have control of time, since even though my examination lasted for hours, when I woke up, only a few minutes had passed." A far simpler explanation is that he dreamed the entire thing.

She really and truly believes this happened to her. Steven's right though, that doesn't make it real.

Well it's definitely real to her, and in the end that's all that really counts. And as far as any brain activity being recorded, or not recorded, maybe the flaw is in that mechanism or measuring device. We don't really know whether that's accurate, I mean it seems to work... sometimes.
I guess the point is that scientific thought is really not a whole lot different from religious thought, in that they are both models of explaining the world around us and lending some kind of order to the whole mess. We look back at the science of the past and can scoff because now we know, but don't think that people in the future won't be doing the same to us.
The main difference between science and religion would probably be empirical observation and an ability to change based upon the observations of others. Still, these observations are subjective though.

hehe moss. also, parnia's explanation of dualism makes no sense. he compares it to a television set interpreting and displaying waves that it yanks out of the air. (at least, I assume that's his comparison, since it's sort of paraphrased in the article.) then he says the brain is doing a similar thing with consciousness, and that the reason brain damage leads to a loss of functionality or a change in personality is not because there's a change in the the soul (or the mind) itself, but because "the apparatus is damaged."

following with this simile, wouldn't a real near-death experience during pronounced brain death be like an unplugged tv playing next week's episode of the simpsons?

or is the analogy flawed because the tv is either on (damaged or otherwise) or off, but the brain has that whole electrical-and-chemical thing going on?

When you die, you die. There is no real evidence to the contrary. Religion is a psychological crutch to comfort us against the concept of endless nothingness, and a whip to keep us from asking difficult questions.

all of you claiming that this is obviously false are just as much "idiots or merely gullible" as the people claiming that it's true. there is no definitive proof either way. you're just arguing theories not facts.

belief in a theory by a majority doesn't make it any more true.

I'm sure Jung would have been amused to see attempts to verify the collective unconscious by experiment.

Brain science hasn't been this much fun since the 1660s, actually. And it's just as contentious: while the methods have become massively more intricate and the data more complex, people are still asking the same questions as Descartes, Willis, Locke and Boerhaave.

And I'd recommend Gerard Edelman as a good read on this topic.

The cultures that produce the wheel, alphabet, etc was quite steeped in superstitions and religious beliefs. This freethinkers bumpersticker is droll and cute, but very simplistic and has a this modern arrogance stink about it.

No one's questioning their capacity for invention. But only in recent years have we been able to retrieve real scientific data as to the physical aspects of the brain at death AND have the capability to revive those who have suffered braindeath. And the information gained from that ability lends credence to the theory that there is not too much happening after you die. If you're looking for arrogance, you'd be more likely to find it on the other side of the argument, since to presume that there must be some sort of life after death assumes that humans have some special spiritual significance in the universe, that there is some God(s) looking out of our well-being. If that's not arrogance - I'm so special that I have all-powerful beings preparing for my death - I don't know what is.

Also, why did this suddenly become a religious issue. Is all 'life after death' explorations truly religious? Does it require things as gods, heavens, hells, etc? I really don't think so, as you can easily come up with "secular" theories of consciousness being a sort of non-local information matrix and such.

Because this question is typically handled in the realm of theology. But you're right, you can certainly come up with several non-theological theories as to what happens after you die. I personally liked the theory outlined in the movie What Dreams May Come. It was very pleasing and comforting. But not very scientific, and without much evidence to support it. For this study, it comes back to this: Of those, 56 said they had no recollection ...

So if we're going to pretend for a moment that we're conducting an experiment here, rather than looking for pseudo-scientific crapola to back "theories" we already believe, you got a 89% "nothing comes after" rate.

In the end, people will believe what they want about anything, regardless of evidence or lack thereof. And as far as this question, it really doesn't matter what you believe - we will all find out for certain all too soon.

Daniel Dennett's Consciousness Explained will tell you why consciousness without the brain is impossible.

Dennett's book builds a huge castle on just a few observations about how we process visual information. His "multiple drafts" model is an interesting possibility, but it's mostly speculation. Moss is right on about him Dennett being a philosopher rather than a scientist. We're a long long way from really understanding what's going on in our heads.

I agree, although I haven't quite finished Consciousness yet. However, he does explain perfectly why Cartesian dualism is a logical impossibility given the assumptions of empirical science, or even the representation/causal model of perception. (To a solipsist such as myself, the question is moot.) Dennett does a great job of explaining how consciousness could arise from the brain (rather than some sort of ethereal stuff), but he still makes no headway on the questions of what consciousness is. Even if you accept a materialist explanation, how are we to know that death can't be followed by, say, reincarnation? Still, it's basically inherently false to claim that a person can think, reason, possess visual images, etc., when their brain is completely inactive.

Dennett's thesis is not the only hypothesis out there (see the Churchlands, and many others), but it makes a lot of sense in many ways and is consistent with what we do know about brain function.

Just because we don't have a final, unassailable answer to a question doesn't mean we can't eliminate preposterous competing explanations. This is a logical fallacy which many people seem determined to fall prey to.
