MORE MATTER, LESS ART?
“Okay, so explain art,” Dr. Ramachandran challenged himself. “The question is, are there artistic universals, just like there are linguistic universals? There is a great diversity of styles in art, but could it be that despite this staggering diversity, there are some common principles, some universal laws? And then, of course, there’s the corollary: how does the brain respond to art?
“I became interested in this when I looked at Indian art,” Dr. Ramachandran said. “Until about five years ago, I had no interest in art at all, but then I started looking at sculptures in Indian temples when I was there on sabbatical. I would see the sculptures of the goddess Parvathi from the 10th century, and this was supposed to be the epitome of everything feminine—of sexuality, sensuality, grace, dignity, and poise—yet the English Victorians took a look at this and they said, ‘It’s hideous! It does not look like a real woman.’ Of course, they were making this criticism because they were unconsciously comparing Indian art with ideals of Western representational art, especially Renaissance and Classical Greek art, and you all know that art is not about representation, it’s not about realism. On the contrary, art is about exaggeration, hyperbole, and deliberate distortion of the image to produce pleasing effects in the mind.
“Now, the great irony is, you come to the 20th century and look at Picasso’s example of a woman. She’s got two eyes on one side of her face, like a flounder, a cleft palate, a club foot, and everything else, and the Western art critics say, ‘My God, what a work of genius,’ because he has liberated us from Realism and made us realize that art is not about realism, it’s about distortion, hyperbole, exaggeration.”
Obviously you can’t randomly distort the image and call it art, Dr. Ramachandran observed. “There are specific types of distortion. I came across a word for this, ‘Rasa,’ in ancient Sanskrit art manuals which means ‘capturing the very spirit of something, the soul of something in order to evoke a specific mood or sentiment or emotion in the viewer’s mind.’ So the idea of art is to change the image in some way to more optimally titillate these 30 visual areas of the brain and excite visual emotions.”
Dr. Ramachandran proceeded to present the example of a seagull chick, which begs for food by pecking at a red spot on its mother’s beak. “Niko Tinbergen found you can wave a disembodied beak or even an oblong piece of cardboard with a red dot and the chick gets fooled and pecks at the dummy. Even more amazing, he found that if you show the chick a long thin stick with three red stripes near the end, the chick goes berserk. It pecks much more vigorously at this and prefers it to the real beak,” he said.
This “super beak” more powerfully excites the “beak detecting” neurons in the chick’s visual pathway “even though this abstract stimulus doesn’t even remotely resemble a real beak,” Dr. Ramachandran elaborated. “If the gulls had an art gallery, they would hang this long stick with three stripes on the wall, worship it, call it a Picasso, and pay millions of dollars for it, even though it doesn’t look like anything they know.” The human artist, Dr. Ramachandran continued, has “stumbled on forms that more powerfully activate visual and limbic centers in your brain than any realistic images. He has created the equivalent of the stick with the three stripes for the human brain.”
Dr. Ramachandran emphasized that these theories and observations are “no more than hesitant first steps toward a science of art—toward discovering artistic universals—the new science of ‘neuroaesthetics.’” To conclude, he returned to the questions about the human mind and consciousness he started with. “What is consciousness? What do you mean by falling in love? What is free will? What is ‘the self’? What is humor, music, art? How did language and abstract thinking and metaphor and poetry evolve in humans? When I was a medical student, these were things you pondered only if you didn’t want to get tenure. Now, given our wonderful imaging technology, if we ask the right questions, do the right experiments on the right patients, we can begin to answer these lofty questions about the mind which until now have remained in the domain of philosophers.”
