Major Breakthrough in Direct Neural Interface
jd writes "In a major breakthrough, neurologists are reporting that they can decypher neurological impulses into speech with an 80% accuracy. A paralyzed man who is incapable of speech has electrodes implanted in his brain which detect the electrical pulses in the brain relating to speech. These signals are then fed into computers which covert these pulses into signals suitable for speech synthesis. As a biotech marvel, this is astonishing. Depending on the rate of development it is possible to imagine Professor Hawking migrating to this, as it would be immune to any further loss of body movement and would vastly accelerate his ability to talk. On the flip-side, direct brain I/O is also a major step towards William Gibson's Neuromancer and other cyberpunk dark futures."
My wife was in a massive car accident, a decade ago. She was in a coma for a month, suffered brain injuries, a collapsed lung, shattered arm, cracked eye socket, multiply broken jaw, etc. A national merit scholarship winner before the accident, her parents were told that, if she survived, she'd likely never walk much or be able to look after herself again.
As it happened, she was sufficiently beaten up at the time that she had no concept of how bad her injuries were. She got out of the wheelchair simply because it frustrated her. She went back to working part time simply because she didn't realize she wasn't supposed to be able to. By the time she comprehended what had happened, she'd improved enough that setting impossible goals like "become a personal trainer" weren't quite so impossible. We taught her to read again (yes, even that got messed up) and even managed to get her back in to school - initially only able to pull a 2.0 average but improved each semester.
In her case, she had an amazing recovery. Yet she, herself, says, "If I'm ever like that again, turn me off." She didn't realize how hurt she was and got lucky with recovering before she did. Understanding now, she has absolutely no desire to try that fight again. She'd rather just call it a day.
So, sadly, there's a real likelihood that his first words, upon realizing he can finally communicate, after years of being unable to and stuck in a totally paralyzed body, will be, "Kill me." Probably not ideal to have the family in the room for.
And yes, that entire story was just so I could "drop" that I have a wife in a slashdot post. Cunning, huh?
The article says the man is 'locked in', which means that he not only cannot speak, but he has no voluntary movement whatsoever, even blinking eyelids.
There was an article recently in New Scientist about this. One problem doctors studying this field have is that since it is an experimental treatment, they need consent of the patient, and how can they get consent if the patient can't communicate?
With some locked-in patients, they are able to respond based on the acidity of their saliva. They are told to either imagine eating lemons (for yes) or eating milk (for no), and their saliva sympathetically adjusts to their thoughts. Then their saliva is measured.

Sad to say it, but I suspect the first thing the patient will say is "kill me".
I have time to kill on lunch. Let's see...
Right Wrong = 10 letters.
P in Prong = 1
M in rigm = 1 (+1 letter missing)
1 missing = 1/2
So, (10 - 2.5)/10 = 0.75 ~ 80%
Your post above not only meets funny standards, but accolades for careful thought in using relevant and accurate choice of words. Well done, sir, well done!
I hope, when they die, cartoon characters have to answer for their sins.
