Carl Zimmer Blog
Just ran across a blog that I'll be reading frequently. It's by Carl Zimmer and you can find it at The Loom. The reason I ran across it was reading the article What If There is Something Going On in There. The subject kind of creepy--is there more than minimal brain activity in people in a vegetative state? The article reports on one 24-year-old guy for whom the answer is yes. Neuroscientists had put this guy into an MRI machine and scanned his brain while playing a tape of his sister's voice. If I'm remembering the article accurately, they found almost normal patterns of brain activity. By the end of the article, the guy has crossed over into full consciousness, being able to communicate reliably by using his eyes.
As I write this, there's a controversial case of the removal of the feeding tube in Florida of a woman who's in a vegetative state. Normally, I wouldn't pay much attention to this sort of story, but in light of reading Zimmer's story, it has really gotten my attention. Indeed, what if there's something going on in there?
Of interest to movement educators: Zimmer reports that the neuroscientist is sometimes able to bring vegetative and minimally conscious subjects to momentary consciousness by putting his fingers deep into their musculature. When he takes his fingers out, they slip back. There is lots of information (and speculation) on movement and plasticity. We see it everyday, especially in tonic functions of clients. But here, there is such a profound effect. Like I said, the article both enlightened and disturbed me.
