So, something has occurred to me over the past years, with all the new neuroplasticity writing coming out.
At last, science is catching up… which is helpful.
And folks are publishing well-researched work, which is both informative and often entertaining. Plus, “citizen journalists” are spreading the word about breaking stories and fringe reports about things that you don’t normally hear about in the mainstream. And YouTube has stories about people who plainly beat the odds. So there.
Like the woman in China who was born without a cerebellum, but is still walking around like a normal person. She’s a bit unsteady on her feet, but she’s still walking around, which she supposedly would not be able to do without a cerebellum.
Or the Israeli soldier who lost the part of his brain that controls speech… talking into the camera like a regular person. Of course, it would be easier for me to assess his skill, if I spoke Hebrew, but he sounded pretty articulate to me.
Or the young many who had half his brain removed by surgery, who is walking and talking and living his life, albeit a little less smoothly than “normal” folks, but still…
What occurs to me, as I see and hear stories of people whose brains have re-routed the activities of damaged/lost portions of their brains, is that all the parts we think are solely responsible for certain functions — like speech and motor control — may actually be primarily responsible for those functions, but not exclusively. It’s like the brain has main thoroughfares for signals — like a freeway heading to the airport — along with a network of service roads that parallel the freeway and can get travelers to the same destination, albeit a bit more slowly and with perhaps a few more bumps along the way.
The idea that specific areas of the brain are the only sources of certain types of processing and control, is being trumped by emerging data that different parts will “light up” in different ways for different people. The basic functionality is the same, but how it’s done varies from person to person.
It’s just like the shapes and sizes of our organs. People have all sorts of variations in their livers, kidneys, spleens, lungs, heart, reproductive organs, muscular structure, brain… you name it. The pictures we see in the anatomy books are “common denominator” depictions — standards which can vary from individual to individual. And it seems more and more like the same holds true of the brain’s functions.
We’re still learning a whole lot, of course, and more research comes out every year (month?) to update our understanding. And we see more and more evidence that it is indeed possible to retrain the brain to do things it’s not “supposed” to be doing.
What I take away from all of this, is that I need to not settle for a “new normal” that leaves me exhausted and dull at the end of each day. I’m looking into ways to strengthen my thinking and improve my endurance, and also to find better, more efficient ways to think. I’ve been adjusting to head trauma since I was a young kid, and I believe it’s led me to use thinking processes that aren’t quite as efficient as they could be. And there are definite areas of deficit that have been with me for a long time — like being very distractable and losing track of where I am in an extended process.
I’ve got this new job ahead of me, and I want to do my best.
Time to recruit more parts of my brain to do the thinking job better.
