Vegetative State Man 'Talks' By Brain Scan
c0lo writes "'Severely brain-injured Scott Routley hasn't spoken in 12 years. None of his physical assessments since then have shown any sign of awareness, or ability to communicate, thus being diagnosed as vegetative (vegetative patients emerge from a coma into a condition where they have periods awake, with their eyes open, but have no perception of themselves or the outside world).' Scott Routley was asked questions while having his brain activity scanned in an fMRI machine. British neuroscientist Prof Adrian Owen said Mr Routley was clearly not vegetative. '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.' As a consequence, medical textbooks would need to be updated to include Prof Owen's techniques, because only observational assessments (as opposed to using mind-readers) of Mr. Routley have continued to suggest he is vegetative. Functional MRI machines are expensive (up to $2 million), but it's quite possible that a portable high-end EEG machine, costing about $75,000, can be used at a patient's bedside. Phillip K. Dick's world is one step closer."
Will they ask him if he wants to die?
If God forks the Universe every time you roll a die, he'd better have a damned good memory.
Sounds like a great use for something like this. But, have fun getting insurance to cover it...
How does one charge $75,000 bucks for something that can be found in the land of open source?

Having to work for a living is the root of all evil.
If even a small percentage of people suffering with "Locked-in" Syndrome are reachable it will be a major win. Think "Johnny Got His Gun" or "The Diving Bell And The Butterfly" for cinematic examples of "Locked-in" Syndrome.
I deny that I have not avoided attaining the opposite of that which I do not want.
While watching "The Diving Bell and the Butterfly", it occurred to me that knowing morse code would give you the best chance of communicating from this frightening state.

I'm not even sure why they let vegetative people live if they've been in that condition for so long. If they're truly unconscious then they're already gone, and if they're not you definitely want to kill them. It makes me sick that we even *potentially* leave people in such a state for so long.
You cannot say that someone else should die, without asking them, simply because **you** imagine you would want to in that situation. That would violate just about every single code of ethics imaginable. The situation changes a bit if they have previously expressed a desire not to be kept alive in such a situation (which is often followed, although mind you even in that case, it's hard to know if they really meant it, since they had no prior experience with which to make an educated judgment), but to presume that another should die because of what you think or want is one of the grossest violations of human rights possible.

Maybe if you're considering Mr. Routely, the man in the article, to be similar to the AM computer from the story. The human protagonist has that thought ("I Have No Mouth and I Must Scream") at the end of the story, but I think what makes that story great was that it really describes the computer. It becomes intelligent, butit's just a world-spanning computer. It has consciousness, but no real purpose, drive or desires, and that's what drives it mad. I find that whole concept really intriguing, because we see a lot of "machines taking over the world" stories in which humans are eliminated because they're considered "inefficient" or simply because the cold, calculating machine sees no value in human life as the machines have no emotions (skynet), but in IHNMAIMS, the computer very much has emotions, it's just that it's hateful. So, instead of humans being eliminated by a machine of cold, cruel logic, they're eliminated and/or tortured by a sadistic machine driven by hatred. Really interesting.
We don't have a state-run media we have a media-run state.
fMRI has problems and is very subject to interpretation, misuse and manipulation.
For example the now classic dead fish fMRI tests:

I am very skeptical of this until it has been repeated, tested and evaluated in other settings by different researchers.
For some reason when reading the story, it really reminded me of "facilitated communication" which is a terrible, cruel scam non-communicative and vegetative or near vegetative state people are subject to. I realize this is different, but really not very different.
Wax on, wax off baby!
I have a legal document that tells my family to pull the plug in such a case. I don't care who thinks I'm a "quitter".

Just because they got results, doesn't mean that there's any conscious thought going on.
Case in point: http://www.wired.com/wiredscience/2009/09/fmrisalmon/
"So, as the fish sat in the scanner, they showed it “a series of photographs depicting human individuals in social situations.” To maintain the rigor of the protocol (and perhaps because it was hilarious), the salmon, just like a human test subject, “was asked to determine what emotion the individual in the photo must have been experiencing.”
The salmon, as Bennett’s poster on the test dryly notes, “was not alive at the time of scanning.”
If that were all that had occurred, the salmon scanning would simply live on in Dartmouth lore as a “crowning achievement in terms of ridiculous objects to scan.” But the fish had a surprise in store. When they got around to analyzing the voxel (think: 3-D or “volumetric” pixel) data, the voxels representing the area where the salmon’s tiny brain sat showed evidence of activity. In the fMRI scan, it looked like the dead salmon was actually thinking about the pictures it had been shown."
Back in 1998, my dad had a brain aneurysm (his second, the first was a ruptured brain aneurysm when he was a teenager that he survived without any impairment othe than an aneurysm clip on his left carotid arterty) that required a coil embolization (a new technique at the time, he was the 7th patient they had done at this hospital). After placing the coils, a clot broke free resulting in a stroke. He was recovering well and was almost fully functional, when two weeks later when he developed hydrocephalus, so they placed a ventriculostomy to relieve the pressure. Two days after that while doing a CT to check the placement of the catheter, they found an infection in his brain stem (later to also note that he had developed a left ear infection), which required a craniotomy. That resulted in him being in a coma and on a ventilator.
The only directive he had ever given me was that he didn't want to live on a machine... That ventilator weighed heavily on me. The doctors told me that he had three days to come out of his coma or he probably never would. In an effort to try to get any type of response out of him, they would twist his nipples so hard that they bled. My sister's 14th birthday was on day 5 of the affair and I decided that there was a difference between living on a machine and recovering from a serious incident for a few days. If he didn't come out of the coma, I would pull him off the ventilator on day 7 - just in case he hung on, I didn't want him to die on my sister's birthday.
He woke up on day 3 and ended up on the ventilator for about a week. It was that incident that finalized his brain damage, Essentially, he was a 41 year old that lost the entire top half of the right side of his brain. He wasn't moving his left side at all, he wasn't able to talk well, his short term memory was totally gone, he couldn't even sit up without falling over and could barely swallow a pureed and thickened diet. After 2.5 months of trying to get him stable enough to leave, he went to rehab where he stayed for another 2.5 months.
After rehab, he came home to live with me... and he regained almost all of his mental faculties. He could walk with assistance, having regained most of the major muscle control in his left leg, but his primary long term deficits were the loss of his left arm and the neglect of the left side of his field of vision. The kicker? He remembers every word that was said to him while he was in a coma. The doctors can't believe that the person they see corresponds to the brain imaging that they're looking at... while they expect that amount of plasticity in a younger individual, it's extremely rare in an adult. Needless to say, he was pretty happy with his life, though he faced the usual depression and whatnot that comes with such a significant change in his lifestyle.
Fast forward to this year... he had mastoiditis in the same ear as that infection back in 1998 and took two courses of antibiotics to get rid of it. Five months later, he went blind and started exhibiting stroke symptoms. I took him to the hospital and he was diagnosed with an abscess in his occiptal lobe (visual cortex) that penetrated the ventricles, causing ventriculits. To do imaging and a lumbar puncture, they ended up needing to sedate him and he ended up on a ventilator. Broad spectrum antibiotics (flagyl, vancomycin, and ceftriaxone) were started that night. A week in, he was, once again, no longer responding to pain.
Once again, I was stuck with confronting my father being on a ventilator and essentially in a coma. Once again, the doctors came through telling me that the odds of survival weren't very good and that, given the previous brain damage to the other side of his brain, now that both sides were involved and with little reserve brain left, he almost certainly wouldn't recover.... but there was still a chance that, if I stopped treatment, he could survive, though it wasn't likely. I decided that my dad would want the only option that gave him any chance of an outcome worse than death, so I co
Don't leave your mind so open that your brain falls out. Don't close it so much that you cut off the blood.
And I'm sure if the guy could communicate more than yes/no he would be saying "Kill me" over and over and over.
this to me is the truly scary part of technology, how they can make someone a "head in a box" for all intents and purposes and leave you going for years trapped in some grey nothing (that is what one girl who awakened from a coma described it as, a grey room with nothing, no sounds, no doors, just a grey room...trapped forever with no concept of time) with no way to escape...fuck that, put a bullet in my brain, smother me with a pillow, OD me on morphine, don't leave me trapped in some grey hell for eternity.
ACs don't waste your time replying, your posts are never seen by me.
Actually, the BBC gave a link to the NEJM article. What have they done with those 5 patients since then?

Willful Modulation of Brain Activity in Disorders of Consciousness

DOI: 10.1056/NEJMoa0905370
Results
Of the 54 patients enrolled in the study, 5 were able to willfully modulate their brain activity. In three of these patients, additional bedside testing revealed some sign of awareness, but in the other two patients, no voluntary behavior could be detected by means of clinical assessment. One patient was able to use our technique to answer yes or no to questions during functional MRI; however, it remained impossible to establish any form of communication at the bedside.
Conclusions
These results show that a small proportion of patients in a vegetative or minimally conscious state have brain activation reflecting some awareness and cognition. Careful clinical examination will result in reclassification of the state of consciousness in some of these patients. This technique may be useful in establishing basic communication with patients who appear to be unresponsive.
"And I'm sure if the guy could communicate more than yes/no he would be saying "Kill me""
Well, he could answer "yes" to the question "do you want us to kill you?",
and "no" to the question "do you want to live a little longer?".
Locked-in syndrome is to me the most terrifying end I can conceive.
