A crash victim thought to have been in a vegetative state for more than a decade has used the power of thought to tell scientists he is not in pain.
Canadian Scott Routley, from London, Ontario, communicated with researchers via a brain scan, proving that he is conscious and aware. It is the first time such a severely brain-damaged patient has been able to provide clinically relevant information to doctors.
British neuroscientist Professor Adrian Owen, who leads the research team at the Brain and Mind Institute of Western Ontario, said: "Scott has been able to show he has a conscious, thinking mind. We have scanned him several times and his pattern of brain activity shows he is clearly choosing to answer our questions. We believe he knows who and where he is."

He said the breakthrough could lead to improvements in the treatment of severely brain-damaged patients who cannot move or speak.

Vegetative patient Scott Routley says 'I'm not in pain'
A Canadian man who was believed to have been in a vegetative state for more than a decade, has been able to tell scientists that he is not in any pain.
It's the first time an uncommunicative, severely brain-injured patient has been able to give answers clinically relevant to their care.
Scott Routley, 39, was asked questions while having his brain activity scanned in an fMRI machine.
His doctor says the discovery means medical textbooks will need rewriting.

(5,763 posts)There was a similar story a couple years ago, although the method of communication wasn't a fMRI. I think it actually had one of the scientists ending by saying the textbooks will need rewriting. They didn't. The results were unrepeatable.
I would wait until this experiment is repeated. There's a history of communication breakthroughs with comatose and autistics that haven't panned out.

(5,763 posts)No, "comatose and autistics" is not an equation.
Saying them together does not make them equal, it means there were hoax cases for one and a hoax the other, the commonality between them being blocked communication. Oh, and by putting "and" between two occurrences of the word hoax, I'm not saying all hoaxes are equal either.
Did you misread that by accident or on purpose?

(40,656 posts)when a family member had strokes.
Here are a handful of examples. I didn't have time to post them until now because I was at work.
50 billion cells are replaced in your body everyday. 500K die every second and are replaced. 50-100k brain cells die each day and get replaced. If memory is in the brain cells and they die what happens to memory? That is the question that brain scientists are stymied about.
I can tell you with stroke members of my family that losing large parts of their brain did not affect their memories. So where are memories stored if not in the brain which dies and is remade constantly, up to sixteen times in your life?
Steven Patt (Institute of Patyholody at Frederich Scghiller University in Germany): Nevertheless all these experiments and descriptions of brain activation processes do not explain how neural activity is the cause for consciousness. Likewise, all attempts which have been undertaken to specify the neurological, information processing and even social theories of consciousness have failed to prove this causal relationship.
Stanislav Grof, MD PHD psychoanalyst, asst. prof of psychiatry at Johns Hopkins U School of Med. And chief of Psychiatric Research at Maryland Psychiatric Research Center: My first idea was that consciousness has to be hard wired in the brain. I spent quite a bit of time trying to figure out how something like that is possible. Today, I came to the conclusion that it is not coming from the brain. In that sense, it supports what Aldous Huxley believed after he had some powerful psychedelic experiences and was trying to link them to the brain. He came to the conclusion that maybe the brain acts as a kind of reducing valve that actually protects us from too much cosmic input... I don't think you can locate the source of consciousness. I am quite sure it is not in the brain-not inside the skull... it actually, according to my experience would lie beyond time and space, so it is not localizable, You atually come to the source of consciousness when you dissolve any categories that imply separation, individuality, time, space and so on. You just experience it as a presence.
Sir John Eccles, Internationally recognized brain researcher concluded that the mind is a separate entity from the brain, and that mental processes cannot be reduced to neurochemical brain processes, but on the contrary direct them. And... a mind may conceivably exist without a brain.
Sir Cyril Burt, Educational psychologist, 'The Gifted Child': :The brain is not an organ that generates consciousness, but rather an instrument evolved to transmit and limit the processes of consciousness and of conscious attention so as to restrict them to those aspects of the material environment which at any moment are crucial for the terrestrial success of the individual.
Consider this: average neuron consists of 80 percent water and about 100k molecules. Brain has 10 billion cells and about 10 to the fifteenth molecules. Each nerve cell in the brain receives an average of 10k conections from other brain cells and the molecules in each cell is renewed about 10k times in a lifetime. We lose about 50000 to 100000 brain cells a day so the total brain cell population is decimated by about 10million cells losing 100 billion cross linkages.
In spite of losing the 'place the brain stores shit' (my sentiments) we still have our memories even really really old ones.
Paul AQ Weiss, Vienna's Institute of Experimental Biology and pioneer in biological research concerning memories remain in spite of cellular and molecular turnover: And yet, despite that ceaseless change of detail in that vast population of elements, our basic pattern of behavior, our memories, our sense of integral existance as an individual have retained their unitary continuity of pattern.
I have known people with hydrocephalic brains which condemned them to having incredibly minimal brain mass but they were able to live normal lives, work and have families and remember. How is that possible to the degree that it has been shown to be if the brain is the repository of memory?
A few places to go and see shit:
it is two part and is part of a BBC documentary on human consciousness. Part 2 is on the list, I think the second one.
I personally had a near death experience having died in front of my sister. I had an experience with my mother and then I came back. My sister slapped the crap out of me to make it happen. I have asked every nurse and doctor I have ever met do you have dreams when you are unconscious? To the last one, I was told no. My pupils were fixed, my skin color was gray and I was dead, dead, dead. The room changed color to black and white and then a pop sounded in my ears. I was in a beautiful place with my mother and then it happened in reverse.
I don't give a fuck who doesn't believe me. I don't care. I know what I experienced and it shows me a lot about life that I would never have known before. I am not afraid to die now because its so damned easy I could almost embrace it.
There are two groups in the world. Those who have these things happen and those who haven't. I believe that the consciousness exists beyond the body or I would not have been able to remember this experience. I was dead. But I remember what happened.
Please notice that I didn't see a light or whatever. I was just there. It was GLORIOUS.
As for the snotty shit that greeted my remarks, what tiny beings you are. Since when is 'science' a simple emphatic no? How sad, sad, sad. But I don't care. The brain is a conduit to our consciousness which is too big for a body that can fail. Otherwise my father wouldn't have had his memories after catastrophic strokes but he did. He was my hero. He remembered everything. So have at it, geniuses. You are on ignore.

Your sources are so great you are deliberately not including them while quoting from them. That tells me your sources are awful.

(6,907 posts)you are overstating neurogenesis here. Although we now know, contrary to former belief, that new brain cells can be produced across the lifetime, the rate is small and restricted to specific small parts of the brain. Consistent with your argument, one of those areas is the hippocampus which is associated to memory, and so it is thought that neurogenesis may play a role in memory. The entire brain does not "die" and get replaced. For the most part, you are born with every neuron you will have. Brain development comes from the blooming and pruning of connections between the neurons, not the growth of new neurons. Plasticity following a stroke comes from "re-wiring" neural circuitry to perform tasks that had been damaged, not from the growth of new neurons. While there is some plasticity it isn't easy. Just my opinion.

(11,843 posts)that means one must actually reside elsewhere and the house is but a conduit to some cosmic abode? Rebuilding and repairing something does not mean that the original functions necessarily must be destroyed or discontinued.
Please understand I do not believe what you are claiming is impossible, but that I believe it is unlikely. I understand that you do not care, it is not my intention to try to change your beliefs. You appear to have faith in your answers and appear willing to ignore any evidence to the contrary. So be it. To the others who may read this, I find several gaps in the leaps taken...
If the garage of my house is torn off in a tornado, it would not prevent the rest of the house from being functional. A stroke does not destroy the entire brain.
The electrochemical processes of the brain do not instantaneously cease the instant that someone decides a person must be dead. They continue until there is not enough oxygen to sustain them. In the case of hypothermia, that could be hours where most people would insist that the victim has to be dead. There is certainly no evidence to support that the brain of someone who survives a near death experience is completely non functional for the duration of the event.

(57,936 posts)You know what you experienced. No one else can know what you experienced. You can't convince other people of things they haven't experienced unless there is some objective evidence. That does not mean that the experience you (or someone else) has had is not true or was not a true experience. It just means that experience was for you. Don't be offended if other people don't believe you. We all have different gifts.
The experience was real. The explanation is not fully known or grasped yet.
Thanks for telling us all about what you lived through.

(40,656 posts)I had read and got slammed. It was just a comment I don't expect or even want agreement on. It was just an observation. I would hope for and expect civility and only you gave it. You always were mannerly and kind. I appreciate that. I don't need anyones agreement on anything.
I am just interested and posted. The shellacking I got was low class. Thank you for showing me what the others will never do-courtesy.

(40,416 posts)Well, there's that one guy who says that and a lot of dualists who think that as a matter of faith.
But neurologists are seeing something different. All consciousness seems to originate in the brain, which is just what one would expect unless you've bought into the ghost in the machine.
