By now, you'd have to be in a coma not to have heard the account of the Belgian man who was diagnosed as being "brain dead" for 23 years, but was recently found by doctors to have normal brain function and who further claims that he had been conscious through the entire period. He's now communicating via a special keyboard and thus is able to finally share his heartbreaking story with the world.
Or is he?
I saw a televised report of this story this morning on a national news show, and what I saw was a "facilitator" using the man's finger to type on a keyboard. I was puzzled about a minor detail: how does she know what he wants to type? The "facilitator" is said to be specially trained to detect - and interpret - faint movements by the subject, and translate them into coherent communications. This is a wonderful skill to possess...if indeed it actually exists.
James Randi thinks it's a "cruel farce," and lays out his impassioned case against "Facilitated Communication," of which, he says, this is simply the most recent example.
I sincerely hope Randi is wrong about this, for the sake of the man's family at the very least. And I'm torn between wanting to believe that this man's new-found communication ability is real and his relationship with his loved ones restored, and wanting to believe that he didn't really endure 23 years of conscious silence. I have a hard time imagining anything worse than the latter.

Proust and the Squid: The Story and Science of the Reading Brain is a delightful rarity: a treatise that will pass the strictest scholarly and scientific scrutiny while being completely accessible - and fascinating - to the layperson. The author, Maryanne Wolf, is a professor of child development at Tufts University near Boston, and she also directs the Center for Reading and Language Research. Her passion is developing a better understanding of how the human brain re-organized (and re-organizes) its own circuitry to permit people to communicate through the written word. But her research isn't limited to the historical or theoretical; she's also determined to find ways to cope "when the brain can't learn to read." And her focus isn't limited to the past or present; she's doing her best to look into the future to see how our transformation into a digital society might affect our reading skills.
The book is less than 250 pages (with another sixty pages devoted to notes, sparing the casual reader a slog through the omnipresent footnotes that mark an academic text), but its breadth and scope are expansive. Wolf takes us through the known history of writing, starting with clay tokens dating to 8,000 BC and which represented the first accounting records; to Sumerian cuneiforms and Egyptian hieroglyphics; to the first alphabet (attributed to Semitic workers living in Egypt around 1,900 BC); with a detour through Greece to explore the surprising condemnation of writing by none other than Socrates, who believed that the access to unsupervised reading would lead to undisciplined thinking, erroneous conclusions, and the destruction of memory.
The author then describes at length what goes on inside the brain when we read. Thanks to advances in brain mapping, scientists can now literally see the process of reading played out across the brain, beginning with visual recognition of the words, followed by word-specific activation, phonological processing (connecting letters to sounds), and, finally, semantic processing (assessing varied meanings and associations), all of which takes place in the normal reading brain in .2-.5 of a second. If this sounds overwhelming, never fear. Wolf considerately places this jargon-heavy science into a neat package of italicized text, and points out that those who aren't all that interested can skip to the next section and be no worse for having done so.
Then, having described how the brain is supposed to handle the process of reading, she delves into those situations where it doesn't work that way. She spends a great deal of time on dyslexia, a syndrome that still isn't fully understood although great strides are being made in that direction. If nothing else, Wolf offers great hope to those who have children or other loved ones who are having difficulty learning to read. She urges calmness and patience in the case of children who seem to be "behind the curve," as the acquisition of reading skills varies greatly among individuals.
Wolf comes by this advice honestly; her children are dyslexic, and she and her husband had several dyslexic ancestors. She presents compelling evidence that dyslexia isn't an unmitigated curse, as there are too many examples of brilliant dyslexics whose contributions to culture and society through the ages are unmistakable and invaluable. In her words, dyslexia, with its seemingly untidy mix of genetic talents and cultural weaknesses, exemplifies human diversityñwith all the important gifts this diversity bestows on human culture.
Finally, Wolf ponders the implications of a digital society, where the traditional written word has been replaced by pixels and sound bites. If the book has a weakness, it comes here, as the subject is given relatively short shrift. But at least one set of questions illuminates one significant source of concern:
I can't think of anyone to whom I wouldn't recommend this book, but I think it's an especially valuable and enlightening resource to three groups. First, educators who teach reading will benefit from the author's insights about how the human brain learns to comprehend the written word. Second, parents of young, pre-literate children need to understand the long-term significance of that seemingly simple things - like merely talking to their children - can have on their ability to achieve effective literacy (pay close attention to her thoughts about "the war on word poverty").
The third group is perhaps less obvious. I think that writers, professional and otherwise, will benefit from Wolf's perspective about the purposes of reading. Writers would do well to internalize the quote that introduces this post and ponder the implication that their words are most successful when they provide not an end, but a beginning ñ a jumping off point where their readers build upon a foundation in ways that the author may not be able to conceive.
