Brains
loom | September 15, 2004The soft spot on a baby's head may be able to tell us when our ancestors first began to speak.
We have tremendously huge brains--six times bigger than the typical brain of a mammal our size. Obviously, that big size brings some fabulous benefits--consciousness, reasoning, and so on. But it has forced a drastic reorganization of the way we grow up. Most primates are born with a brain fairly close to its adult size. A macaque brain, for example, is 70% of adult size at birth. Apes, on the other hand, have bigger brains, and more of their brain growth takes place after birth. A chimpanzee is…
loom | September 1, 2004"A world without memory is a world of the present," Alan Lightman wrote in Einstein's Dreams. "The past exists only in books, in documents. In order to know himself, each person carries his own Book of Life, which is filled with the history of his life...Without his Book of Life, a person is a snapshot, a two-dimensional image, a ghost."
Most people would probably agree with Lightman. Most people think that our self -knowledge exists only through the memories we have amassed of our selves. Am I a kind person? Am I gloomy? To answer these sorts of questions, most people would think you have to…
loom | June 30, 2004Our brains are huge, particularly if you take into consideration the relative size of our bodies. Generally, the proportion of brain to body is pretty tight among mammals. But the human brain is seven times bigger than what you'd predict from the size of our body. Six million years ago, hominid brains were about a third the size they are today, comparable to a chimp's. So what accounts for the big boom? It would be flattering ourselves to say that the cause was something we are proud of--our ability to talk, or our gifts with tools. Certainly, our brains show signs of being adapted for these…
loom | June 15, 2004In the New York Times this morning, the poet Diane Ackerman has written an essay about the brain, in which she waxes eloquent about its ability to discern patterns in the world. The essay is distilled from her new book, An Alchemy of the Mind, which I've just reviewed for the Washington Post. I didn't much like the book, although it took me a while to figure out what was bothering me about it. If you read the essay, you can get the flavor of the book, not to mention Ackerman's general style in her previous books (which have taken on subjects such as endangered species and the senses).…
loom | June 1, 2004I always like book reviews that combine books that might not at first seem to have that much in common. In the new issue of Natural History, the neuroscientist Williams Calvin reviews Soul Made Flesh along with The Birth of the Mind, a fascinating book by Gary Marcus of NYU. If you haven't heard of Marcus's new book--which explores how genes produce minds--definitely check it out.
loom | June 1, 2004It's strange enough hearing yourself talking on the radio. It's stranger still to see a transcript someone makes of you talking on the radio. Recently I was interviewed about Soul Made Flesh on Australian Broadcasting Corporation's show "All in the Mind." Instead of an audio archive, ABC has posted a transcript of the show. While I can't claim I spoke in perfect paragraphs, we had an interesting talk about how the brain became the center of our existence.
loom | June 1, 2004I was asked a couple weeks ago to contribute a piece to a special series of articles in Newsweek about the future of Wi-Fi. I must admit that a fair amount of the stuff that's on the Wi-Fi horizon seems a little banal to me. It's nice to know that I will be able to swallow a camera-pill that will wirelessly send pictures of my bowels to my doctor, but it hardly cries out paradigm shift. On the other hand, I've been deeply intrigued and a little disturbed by the possibility that the next digital device to go Wi-Fi is the human brain. Here's my short essay on the subject.
loom | April 21, 2004My book Soul Made Flesh looks at the roots of neuroscience in the 1600s. The first neurologists saw their work as a religious mission; they recognized that it was with the brain that we made moral judgments. In order to finish the book, I looked for living neuroscientists who carry on those early traditions today. I was soon fascinated by the work of Joshua Greene, a philosopher turned neuroscientist at Princeton. Greene is dissecting the ways in which people decide what is right and wrong. To do so, he poses moral dilemmas to them while he scans their brains. I mentioned Greene briefly in…
loom | April 3, 2004This week I am in England to give some talks about Soul Made Flesh, which has just been published here. In addition to talking on the BBC, I'll be talking at Blackwell's in Bristol on Tuesday, and at the Museum of the History of Science at Oxford University on Wednesday. I've posted details and links to even more details on the talks page of my web site.
It's a bit daunting coming here, the very place where much of my book is set. But the response has been kind so far. This morning the eminent historian Lisa Jardine wrote a generally good review in the Sunday Times. Meanwhile, stateside,…
loom | March 24, 2004In February I wrote an article in Popular Science about a project to implant electrodes in a monkey's brain allowing the monkey to control a robot arm with its mind. The goal of this work is to let paralyzed people operate prosthetic limbs by thought alone. Now the research team has announced another big step in that direction: their first work on humans.
They implanted their electrodes into the brains of people undergoing surgery for Parkinson's disease and tremor disorders, and then had the patients play a video game with a joystick. (In brain surgery, patients don't get general anasthesia…
loom | March 23, 2004Attention Virginian readers of the Loom: I'll be heading to warmer climes later this week to speak in Charlottesville at the Virginia Festival of the Book. On Thursday at 4 I'll be speaking on a panel about science and society. On Friday at 4 I'll be speaking again on scientific discoveries and how they change us. I'm looking forward to listening to my fellow panelists, who include Robin Marantz Henig and James Shreeve. See you there.
loom | March 22, 2004I've posted a new batch of reviews for Soul Made Flesh on my web site. The newest is from Ross King, the author of Brunelleschi's Dome and Michelangelo and the Pope's Ceiling. His review in yesterday's Los Angeles Times is a rare sort--he likes the book (which he calls "thrilling") for what the book really is, rather than as a projection of some phantom in his own mind.
A review of a different sort comes from Simon Conway Morris of the University of Cambridge. Conway Morris is a first-rate paleontologist who has shed a lot of light on how the major groups of animals alive today emerged in the…
loom | March 17, 2004Three weeks ago, I gave a talk at Stanford University about my new book Soul Made Flesh. A wonderful crowd turned out and peppered me with excellent questions afterwards, each of which could have become new talks of their own. CSPAN was there to film it, and they'll be broadcasting the talk this Saturday, March 20, at 9 am EST on BookTV.
You may want to check out this little RSS a commenter forwarded to me that converts the BookTV schedule to any time zone. Also, if you miss the talk, it will probably repeated on another weekend, so check back to their site.
Here's an added incentive to…
loom | March 9, 2004When George Bush quietly dismissed two members of his Council on Bioethics on the last Friday in February, he probably assumed the news would get buried under the weekends distractions. But ten days later, its still hotsee, for example, two articles in Slate, and an editorial in the Washington Post, as well as Chris Mooney's ongoing coverage at his blog. Bush failed to appreciate just how obvious the politics were behind the move. The two dismissed members (bioethicist William May and biochemist Elizabeth Blackburn) have been critical of the Administration. Their replacements (two political…
loom | March 9, 2004Over on my web site I've posted an article I've just written for the Sunday Telegraph Magazine in England about an eerie brain disorder called musical hallucinosis. You've probably had a tune stuck in your head for an hour at least once in your life. Now imagine that the tune played all day and night--and imagine that it sounded as real as if a marching band was standing by your window.
Here's how it starts:
Janet Dilbeck clearly remembers the moment the music started. Two years ago she was lying in bed on the California ranch where she and her husband were caretakers. A mild earthquake woke…
loom | March 2, 2004If you want to hear about brain science at its birth and today, check out the public radio show Tech Nation, this week. In the first half of the show, I'll be talking about Soul Made Flesh. In the second half, Steven Johnson will be talking about his excellent new book, Mind Wide Open. You can find out where and when you can listen to the show at the program's web site, or listen to it on their site archive.

loom | February 18, 2004If you live in the Bay Area, please join me noon on Monday, February 23, at Stanford University for a talk about Soul Made Flesh. (Here are all the details.)
The talk is sponsored by the Stanford University Center for Biomedical Ethics and the Stanford Brain Research Institute. It's gratifying that such great organizations that are dedicated to twenty-first century neuroscience are interested in the adventures of a motley crew of seventeenth century alchemists and natural philosophers.
The talk is free and open to the public. And if that's not incentive enough, CSPAN will be there to film…
loom | February 9, 2004I'll be on Fresh Air with Terry Gross today, talking about Soul Made Flesh. If you miss it today, it will be archived at the show's web site.
loom | January 26, 2004If you're in New York, you've got two chances on Tuesday January 27 to hear me talk about Soul Made Flesh. At 5:30 I'll be giving a talk in the "Mind Over Body" lecture series at New York Public Library's Science and Industry Branch at 188 Madison Ave. I'll then be heading to the East Villiage to talk in the more intimate setting of KGB (85 E. 4th St.) at 7:30. Both events are free.
loom | January 19, 2004At noon today in New York I'll be at the Makor Center of the 92nd St. Y at 35 W. 67 St. to talk about Soul Made Flesh.
