The mind is a master of art

TelegraphNewly hatched gulls get their food by pecking at a red spot on their mother's yellow beak. The birds don't even need their mother to be present - they are as happy pestering a disembodied beak as the real thing.

But 50 years ago Niko Tinbergen, an Oxford University scientist, made an extraordinary discovery. When presented with an abstract version of the beak - a yellow stick with three red stripes - the chicks went crazy. The stick excited the baby birds far more than their mothers' bills.

Tinbergen's creation bore no resemblance to a real beak and yet to the birds' brains it was somehow more "real". By exaggerating the reality of a beak, Tinbergen did what all artists strive for - he captured the essence of reality.

The experiment raised intriguing questions about the nature of art. If a hyper-real painting triggered such a reaction in the visual processing regions of a bird's brain, might not art be doing the same in human minds?

Vilayanur Ramachandran, professor of neuroscience and psychology at the University of California, San Diego, author of The Emerging Mind and one of the world's leading neuroscientists, believes the answer is yes.

Best known for his groundbreaking work on phantom limb disorders and visual perception, he is calling for the same approach to the study of art that was used by Noam Chomsky to revolutionise linguistics in the Sixties. Just as Chomsky argued that the human brain is hard wired with rules of language, Ramachandran believes the brain may be hard wired to appreciate art.

He concedes that most art is culturally determined. Tastes vary over time and space. But even if 90 per cent of art is culturally driven, 10 per cent may be driven by universal laws linked to the way the brain has evolved to process vision.

"The science of art sounds like an oxymoron because art is about individual human experience, creating originality. Science seems to be dealing with universal principles - the opposite," he says. "But I believe the brain has evolved principles that allow you to deal efficiently with the visual world. They allow you to capture objects, identify objects and mate with objects."

The starting point for Ramachandran is the fact that the brain actively processes and interprets visual signals. "The eyes are not cameras. They don't take an image, send it down the cable and get it displayed on a screen in the brain. Clearly the image is encoded in the form of nerve impulses.

"It's a symbolic description in the brain, the analogy of which would be a piece of paper on which you write something about your house. The squiggles of ink bear no resemblance to your house but a person can decode the letters and conjure up an image of your house.

"The brain is using a similar code, which is where art comes in. Humans have art because the brain actively must process the signals coming from the retina."
Artists manipulate, distort and exaggerate images to optimally titillate the 30 areas of the brain dealing with vision.

news : "December 29, 2003 -- WASHINGTON - Startling new Army statistics show that strife-torn Baghdad - considered the most dangerous city in the world - now has a lower murder rate than New York. The newest numbers, released by the Army's 1st Infantry Division, reveal that over the past three months, murders and other crimes in Baghdad are decreasing dramatically and that in the month of October, there were fewer murders per capita there than the Big Apple, Chicago, Los Angeles and Washington, D.C. The Bush administration and outside experts are touting these new figures as a sign that, eight months after the fall of Saddam Hussein, major progress is starting to be made in the oft-criticized effort by the United States and coalition partners to restore order and rebuild Iraq. 'If these numbers are accurate, they show that the systems we put in place four months ago to develop a police force based on the principles of a free and democratic society are starting to
Forum: The fish that threatened national security : "At La Guardia we proceeded to security and the X-ray inspection point run by the Transportation Security Administration. I have learned by now that, post-9/11, a traveler is better off safe than sorry when proceeding through security. I wasn't prepared, however, for the TSA to stop me right at the entrance, proclaiming that no small pets, including fish, were permitted through security. I had, however, just received the blessing of the ticket agents at US Airways and pre-assured MJ's travels with Pittsburgh International Airport security weeks before our travel date. I tried to explain this to the screener who stood between me and the gates, but she would have none of it. I was led back to the US Airways ticket counter, stocking-footed and alone, where the agents reasserted that they did not see a problem for me to have a fish on board, properly packaged in plastic fish bag and secured with a rubber band as MJ was.
