Stem Cells Turn Hearing Back On

puddingebola sends this excerpt from an article at ScienceNow: "Scientists have enabled deaf gerbils to hear again — with the help of transplanted cells that develop into nerves that can transmit auditory information from the ears to the brain. The advance, reported today in Nature, could be the basis for a therapy to treat various kinds of hearing loss. ... Rivolta and his colleagues knew that during embryonic development, a handful of proteins, including fibroblast growth factor (FGF) 3 and 10, are required for ears to form. So they exposed human embryonic stem cells to FGF3 and FGF10. Multiple types of cells formed, including precursor inner-ear hair cells, but they were also able to identify and isolate the cells beginning to differentiate into the desired spiral ganglion neurons. Then, they implanted the neuron precursor cells into the ears of gerbils with damaged ear neurons and followed the animals for 10 weeks. The function of the neurons was restored.'"

      I can respect that.

      Something that you deal with all your life becomes normal for you. Changing that norm, even for the better, can be frightening and jarring (I speak from experience). I can certainly see how being deaf one minute and normal hearing the next could very likely cause a sensory overload.

      However, that shouldn't preclude such research. I can't imagine such an opportunity being turned down by someone who lost their hearing at some point in life.

      Deafness/blindness that occurred later in life (injury, disease, etc.), sure. But for people who were born that way, or who lost their hearing too early to remember, probably not so much. Opening a facet of the world to someone who has spent their entire life with no concept of it can be exceedingly shocking, even traumatic. A little on this is discussed in the wiki article on recovery from blindness, but a much more interesting account is written by Oliver Sacks about Virgil, a man whose vision was partially restored at age 50 after a lifetime of blindness (short on time, so I can't a link, but Google should have it somewhere). In a nutshell, Virgil's experience with sight was like trying to get your grandfather to play a video game. He understands what it is, but sees it as a novelty, something that's extraneous and totally unneeded. Worse, he's bad at it, and knowing that he's bad at it makes him frustrated when you try to get him to play.

      Virgil was not a happy man after his surgery. He lapsed into depression and pretty much lost the will to live. So be careful when you start proclaiming that people simply don't know what they're missing - they might be better off that way at thsi point.

      Virgil is an anecdote. We have no access to a parallel universe in which a "control Virgil" lives who hasn't had his sight restored. Maybe that Virgil would have lost the will to live anyway. Virgil died of pneumonia only four months after the surgery. So all that we know about his experience is confined to a few weeks or months following the restoration of sight, not how he would have coped in the long run.

      as somebody who spends a good chunk of time dealing with hard-of-hearing subtitles, it seems a little... entitled for certain vocal members of the community to not accept a "cure" (i've seen x-men 3, i know the issues), but expect placing the burden of making adjustments to fit their condition on other people (necessarily - you can't make subtitles if you can't hear the dialogue).

      hopefully this wont be taken out of context as flamebait - i have much respect for the deaf community, i can understand it. but they above all other disability groups seem to be the most political. and as with all politics, it's not always something that makes sense. my wife's worked in disability (and has mild CP herself), so i'm not pulling facts out of my nethers but speaking from experience.

      who can argue that it's not a disadvantage?

      The deaf, apparently. We live in a world of noise, and hearing is a sense that you can never turn off, so sometimes being deaf is a big plus.

      But mostly, this is the whole deaf culture thing. Consider that the main drawback to their disability is that it hinders communication with non-deaf, non-signing people. (That's why they need TTY, CC, etc.) Among themselves, the disability has very little practical impact (unlike, for instance, blind people), especially if you were born that way and it's all you've ever known. And of course, like all communities, the deaf have developed norms and conventions for interactions that are specialized to their unique situation.

      Got the picture so far? Now imagine you're deaf and your social circle is deaf and you frequently have to venture out into society at large where interaction with the others is always difficult and frequently gets you strange looks, unsolicited pity, and subhuman regard. The insurance guy down-talks you (as if your IQ was 70), and you get tried of folks repeatedly trying to communicate with you by SHOUTING LOUDER or talking reeeaa-aaaallll slo-wwww-lllley when all they need to do is talk straight and use a little common sense. Do you see what's happening here? Interacting with your deaf peers is clearly "normal" and comfortable. The problem is with the world-at-large.

      Finally, that world-at-large comes to your door and wants to "fix" poor, miserable little you. Or worse, they want to "fix" your newborn child: do surgery on their head so they won't have to live with the same "disability" you do. Let that child grow up as one of the others such that there will always, always be that extra rift between you and your offspring. And what, over the long haul, will these "fixes" do to your community but choke it out and make it disappear?

      That is very, very threatening.

      "Deaf culture" is the reason that the deaf community suffers from severe unemployment and illiteracy. Deaf culture is the reason so few deaf people pursue higher education. It's what keeps competent teachers and administrators out of deaf schools (you know, the ones who aren't "deaf enough"). Worst of all, it breeds fear and hatred; keeping the deaf community isolated.
