I know I’ve written about neuroplasticity on this blog before, but it continues to be a subject that fascinates me – partly because of my interest in biology and psychology, partly because I’m experiencing its repercussions every day. In that vein, I recently finished a book on the subject that I really, really recommend: The Brain that Changes Itself, by Norman Doidge.
This book is more than nerd reading. Sure, it delves into the complexity of brain systems and neural anatomy, which was enough to make the biology student in me leap in glee. But it does something more: it lends scientific credibility to the idea that our thoughts do make a difference, that we can change ourselves in unprecedented and positive ways, if we put in enough effort. To an extent, we have a stronger hand in shaping our own minds and our own fates than we sometimes think. This happens not only on an abstract level, but also in terms of concrete physiological change. At the risk of sounding cheesy, I admit I found Doidge’s assessments and anecdotes genuinely inspirational.
The book is a nice blend of scientific insight and personal stories, some of them verging on the bizarre. We meet a woman who functions astonishingly well with only half of her brain, stroke patients and children with cerebral palsy who have been able to overcome many of their obstacles, plus people who have been able to correct learning disabilities and self-destructive behaviors through concentrated therapy and practice. Although cochlear implants are only mentioned briefly, this book’s exploration of neuroplasticity is closely related to what I am going through. And, dare I say, learning to hear is nothing compared to what some of these people have experienced!
To reiterate, learning to hear (or to do anything else) is not about the ear, it’s about the brain. That my brain can radically change its architecture so late in my life, that it can accept new input and form increasingly complex neural connections, in order to gain and fine-tune a sense that I’ve never had before: amazing. (The book talked about colorblind people who can learn to “see” color through hearing specific tones, about visual cortex prostheses to assist with blindness, about a device that uses the tongue to restore the vestibular system, about triggering specific sensations through electromagnetic stimulation. Mind-boggling. I love biomedical engineering.)
In a nutshell – I am not static, I am dynamic and receptive to change. That’s an empowering thought. When I first started reading this book, it was during the difficult early days with the CI, a time when everything seemed to have been turned on its head. Look, the pages said to me, just because change starts slowly does not mean things won’t get better. It’s like picking a trail up a hill, step by step. Each step seems to accomplish little more than the one before it. But within a surprisingly short amount of time, you raise your eyes from your feet and find yourself atop a bluff, marveling at how far you’ve climbed. On to the next peak!
Some days, I needed that encouragement badly. I think everyone does. Isn't change motivational?

Yeah, Stanford!
Go Stanford!
Last month, Stefan Heller and other researchers at the Stanford Medical School published a huge breakthrough in inner-ear stem cell research. Over the last few weeks the news has been all over: I've heard about it through the New York Times, through deaf networks, and through classes here on campus. The biology nerd in me finds it beyond cool, and I thought I'd post it here:

Though it may never directly affect me, Heller's research is unbelievably relevant to the process I am going through. When I was considering my implant, one of the questions I asked was about the status of recent stem cell research, and whether it would ever be a feasible alternative to a CI. This has always been one of my reservations about CIs: should I go ahead with a surgery that will likely destroy most, if not all, of the residual hearing in my cochlea, when there might be huge technological advances a few years down the road? Is it better to hold out?
My doctors' answer was no. If researchers like Heller ever make significant strides with stem cell therapy for deafness, clinical trials are at least ten years away. No sense in waiting for that, if a CI can help me here and now.
Of course, this stem cell research is not without its controversy. It brings up the Deaf objection that deafness is not a disease that needs to be "cured." To put it lightly, Deaf people find it offensive whenever hearing people dare tackle projects like this. As for what I think about that? Let's just say that it's suddenly become very complicated.
