Art and the Brain - Vilayanur Ramachandran

Dr Vilayanur Ramachandran, a professor at University of California, San Diego has written a book titled "Phantoms in the Brain." This book talks about patients with unusual problems that he discovered to be neurological, rather than psychological. Such patients, and their maladies, also gave him insights into how the brain functions. He also developed a fascinating theory into the nature of beauty and art, about which he spoke a few years back at Tamil Heritage Trust. Recently, he lectured on this topic organized by Apparao Galleries, and held at the Leela Palace Hotel.

These are my notes of that lecture, in Ramachandran's voice.

Vilayanur Ramachandran on Art and the Brain

When I visit India, I enjoy visiting the Kapali temple in Mylapore. I also try to go to several other temples. Sculptures in our temples, and bronzes, hold a strong attraction and have fascinated me for their beauty.

CP Snow wrote a famous essay titled "Two Cultures", about the Arts and the Sciences. His contention was that "Never the twain shall meet." I'm going to argue that Snow is wrong. Lord Reith said there are some people whom it's one duty to offend, and I'll exercise that duty.

Are there universal aesthetics? How does the brain respond to art? Noam Chomsky discovered a universal principle to language. I'll argue that there is a universal principle to art, not just across cultures, but across phylogenetic divisions. Flowers evolved to be beautiful to bees and butterflies four hundred million years ago, not to humans. We didn't evolve from bees, but we have arrived at a similar aesthetic to appreciate flowers.

Bower bird, a tiny brown bird, builds massive bowers from moss and twigs and cigarette foils and trash and other material to create a large bower, that people would not believe were created by a bird.
I recently visited Mamallapuram.

Some of the Victorian Englishmen had who visited India had contemptuous views on Indian bronzes. A Parvati bronze, they claimed, was ugly and unrealistic, and therefore, primitive. Waist is too thin, breasts are too big, face is not realistic, Indian art is not proportional - these were some of the critical comments. The irony was that some Englishwomen had their ribs surgically removed from to narrow their waists, to appeal more to English men, at the same time that they were faulting the Chola bronzes for unrealistic waists! I have seen the skeletons of such women in London. And modern western art, distorts perspective, but is lauded for "liberation from the tyranny of form."

The point of art is not to caputre realism (which a photo can do, but may not be called art).
The word rasa is often seen in Sanskrit literature, hard to translate, but an emotion Art tries to provoke. I study vision - my eyeball captures an upside down image of what you see, via  a cable - the optic fibre. But who sees that image? There is no second person inside your brain seeing it, or there would have to an infinite series of such persons. What the Brain creates is a symbolic image of what you see, and captured by billions of neurons and synapses.

Look at these pictures, this first one could be a young lady looking away or an old lady's left profile, it is a dual image.

Old Lady / Young lady illusion
A similar dual image is this duck / rabbit (facing opposite directions) - the rabbit's ears double as the duck's beak.
Duck / Rabbit Dual image

Art works because you can take advantage of these brain mechanisms, to titillate a viewer. A Necker cube is another such illusion, where the same cube can be seen in two different perspectives.

From these studies, I have drawn up what I called Seven Laws of Art. These are not final, there may be more.

Cultural variation in Art has been studied to death, it's called Art History.  I'm interested in the biological explanation behind the commonality.

Grouping is to escape predators. A lion behind foliage is not interpreted by the Brain as several fragmented lion colored objects, but as a lion. This evolved as an evolutionary mechanism to help in survival. This principle is exploited by fashion designers and artists.

Look at this picture. It seems to be just a bunch of dots, but some of you can see a Dalmatian. How many see it, raise your hands. Not everyone can see it right away, but once you see it, the dalmatian never goes away.
Dalmation - an example of grouping

Peak shift  If you show a rat squares and rectangles, and reward it with cheese when it moves towards a rectangle, it soon learns a preference for rectangles. When you then show it a narrower rectangle, it prefers that to an earlier reactangle. The rat learns rectangularity not a particular rectangle. This, is the essence of Caricature.You amplify a person, say Obama or Nixon and exaggerate what differentiates him from the average person. Draw Nixon with a more bulbous nose and larger ears than normal, and it looks more like Nixon than Nixon himself. This is what a Chola bronze artist accomplishes. He captures peak shift.

A biologist Timbergen studied how seagull chicks recognize their mother. He observed that the seagulls he studied had with red spot on the edge of their beaks. A chick pecks the spot and the mother bird regurgitates the food. Timbergen used a beak from a dead bird, and the chick pecked that for food. Next he used a long stick with red spots. A stick with three stripes caused high obsessive pecking from the chick's than the actual beak! This is also peak shift. Which artists have tapped into, and captured the imagination of public.

Principles of Understatement and Isolation These play a major role in art, too. Doesn't this contradict peak shift? No, the brain uses multiple parallel mechanisms. An outline of a woman's form captures more than color or attitude. The outline itself excites a viewer, more than other aspects and an artist who depicts this grabs the attention of the viewer.

Artistic metaphor Nobody knows what that is. Why are metaphors beautiful? Why not just say what is original or descriptive? Artists poets and novelists indulge in metaphors, and a master like Shakespeare profusely uses them. But it's not just artists. An average person's language, not just those of poets, can have upto thirty percent metaphors.

Q&A

Q Is there such a thing as bad art? Isn't the beauty of art in the beholder's eye?
A Yes there is bad art, in the USA, we call it Kitsch. Once you have enjoyed fine art, Kitsch doesn't appeal anymore. I don't think one man's Kitsch is another's fine art.

Poetry and Art should be introduced early in the curriculum. Thanks to Macaulay, we teach grammar early in our system, which is not very useful. This will help us develop a taste of fine art and not indulge in kitsch.

Q You talked about humans, mammals and birds and their sense of beauty? Do another animals have such a sense of beauty too? Reptiles or fish, for example?
A Birds are diurnal, so are humans, and we see far better than we smell. So we have more in common with birds visually. Reptiles are olfactory, they sense the world primarily with smell. This is also why reptiles are not as colorful as birds. Humans have a very poor sense of smell, compared to their vision.

Q Does peak shift apply only to visual art or also to music or sounds?
A One third of the Brain deals with vision, and we have 150 years of research on visual perception. We are poorer in hearing, and there is less research about this area also.

But there is some universal element in appreciating art. Eight of ten times, in my experiments, Americans who have never heard Carnatic music can pick Durbari Kannada as evoking sadness and Mohanam as evoking Sringara. Can't explain this in left brain terms. Durbari Kannada, I suggest, uses peak shift to take parental separation anxiety and exaggerates it to evoke a separation anxiety from God.

Common principles cut across the senses, which come together in the parietal lobe.

Q We seem to like symmetry in art, but sometimes asymmetry appeals too. Do you think this is because of peak shift?
A Symmetry is universal. But a slight asymmetry can be very appealing. The purpose of art, for biologists, is to detect biological objects. Symmetry appeals because it indicates a living thing.

Bus Stop Index

I have a fascination for buses, as some people do for trains, ships, trams, cars, motorbikes, and yes rockets. I take being a connoisseur of the commonplace seriously. Buses are perhaps the least appreciated, definitely the least glamorous, of motorized vehicles. Even bicycles are far more fashionable. Bicycle snobs abound; no bus snob exists. Part of the static infrastructure of buses is bus stops, where people wait. I believe buses and bus stops reflect a community, a government and the economy.

Buses are one of the miracles of the 20th century, far more important for freedom and prosperity than most measures dealt with by economists. Economists use such measures as Consumer Price Index(CPI), Gross National Product (GNP), inflation, growth rates and the Gini coefficient - most people understand these poorly, and journalists, bureaucrats and social activists often have such a poor understanding of these, that their ignorance might be more useful. Mathematicians, fortunately, find these so practical, that they avoid them altogether.

I think a bus index and a bus stop index may be one useful index of the economy. The former is a index for the economy, with fares, people transported, times of operation, seating capacity, and being useful information. A bus stop index would merely reflect the aesthetic standards of a community, or the degree of apathy or engagement of local government. In Madras for the last few years, there are no bus stops in most places, so no shelter from rain and sun. This is purely a contractor issue and political one-up-manship.

Here are a few regular and a few unusual bus stops, that caught my eye, usually, when I was in a bus and had my hands free.

Kerala

Politics permeates every aspect of Kerala life, bus stops are no exception.

Thiripparaiyaar
Notice the post box on one of the pillars. And the complete absence of movie or business or siddha doctor pamphlets plastering the surfaces, unlike in Tamil Nadu.

Thiru Vallam - Congresss pillar
Thiruvallam - I took the photo from inside the bus stop. These are Congress colors not India colors, there are party flag posts outside. It has 3 seats, not in photo.

Trivandrum East Fort
I found this bus stop in Trivandrum city, near the Padmanabha Swamy temple. I like the aesthetic touch of the paavai vilakku (Lady with Lamp) statue aesthetically pleasing, though orange paint would not be my choice.

TamilNadu

Thiruneelakkudi - near Mayiladuthurai
You have to admit, that the bus stop at Thiruneelakkudi is more fancy than some houses or government buildings.

Suchindram
This one at Suchindram, the bus stop for the main temple, has a roof, slight modeled on a temple vimana, with kalasams on top!

Gujarat

My bus stop index idea is a recent one, and I took a few pictures of bus stops and buses while in Gujarat. This first yellow paint square shelter, outside Bhuj, is typical of rural areas, even in TamilNadu.

Bhuj

Naroda, Ahmedabad
This is a bus stop in Naroda, a suburb of Ahmedabad, with a long bus stop, and a few seats and a tea shop. Also quite typical. The next two, are the interior and exterior of BRTS bus stops in Ahmedabad - very atypical. Pune and Delhi are two other cities with BRTS. The one in Pune is a farce; I haven't been to Delhi.

BRTS bus stop - interior - Ahmedabad

BRTS  bus stop Ahemdabad
This one below, in Baroda, is actually more typical. A simple bus stop in Baroda, one of the cleanest cities I have seen. I did not see many buses in the early mornings, though. In Tamilnadu and Kerala buses are quite common, even in the early mornings. North Indian winters are cold, those states wake up late, so that's not a surprise.

Baroda

Mehsana
Finally, Mehsana, a small town with a simple bus stop. Sadly, still better than most of Madras.

The Art and Aesthetic of Driving

I saw the movie Rush on TV last weekend, while Narendra Modi was orating in Madison Square Garden in New York. The movie is about the Formula One racing – particularly the contest between two drivers, Niki Lauda of Austria and James Hunt of England. Racing is the only thing they have in common – their characters are diametrically opposite.

James Hunt is a womanizer, aggressive, muscular, handsome, utterly contemptuous, a bag of testosterone that artists decry in life and celebrate in art.

In one scene, Lauda is given a lift by a woman, Marlene. He hasn’t told her that Ferrari just signed him up. He makes remarks about various aspects of the car. When the car breaks down, she tries to use her sex appeal to get a lift. A passing car stops – not for her, but recognizing Niki Lauda – and they ask him to drive their beat up old car. This is how Marlene discovers who he is. “You cant be a Formula One driver,” she says. “They have long hair, they are sexy, shirts open upto here...” she pauses. “Besides, you are driving like a old man.” Lauda merely smiles!

“Why don’t you drive fast?” she asks.

“There is no need to drive fast,” he retorts. “It increases the percentage of risk. Right now, there’s no reward, no incentive.”

Lauda’s reply is astounding, for any driver. Formula One driver, it is totally unbelievable.

In the brilliant cinematic moment, that every race fan waits for, Marlene challenges him, when he calmly asks, “Why should I drive fast?”

“Because I am asking you to.”

It’s brief, all cuts and flashes and sound effects, but for the next few seconds of film, there’s shifting of gears, the roar of the engine and the uncontrolled excitement of the guys who gave Niki Lauda a lift as he careens their ordinary car through the Italian country side. And Marlene for the first time, discovers acceleration. We have seen far better scenes of car racing, and some terrific driving and road stunts, in movies like Ronin or Iron Man, with far larger budgets. Considering how much time is devoted in movies to races and chases – in bikes, cars, planes, trains, boats etc., the general opinion is that driving fast is the ultimate skill on the road. It is exactly this aspect, and that of living fast, that the movie’s other character, James Hunt displays.

In this context, it is utterly amazing, that the philosophy of driving as espoused by Lauda, actually made it to a film on car racing! I have only known about Lauda’s name – and all I have seen of car racing is mostly Formula 1 or CART on TV. Other races like Nascar, Le Mans etc don’t interest me, and bike racing rarely does either.

Alistair MacLean’s The Way to Dusty Death is a terrific book about the racing world, is a terrific read. But it is a crime story and about racing, not driving. Reader, if there are any books you know about driving – please let me know.

Lauda’s philosophy is about driving. Anyone who takes pleasure in driving a car, derives pleasure in how it responds, how it growls, how it takes curves, the feel of accelerational gravity, how the car eats tarmac, how it glides smoothly sideways, the pleasure of overtaking a whole bunch of cars, the recognition of other drivers or the mild envy or admiration when they see you do something special on the road – such a person knows the pleasure of driving, not just the pleasures of the scenery on the road. Few of us ever drive a racing car or on a race course. For those few of us lucky enough to have driven a sports car, with an engine that can growl and squeal and slice through the wind and delight and exhilarate and put a grin on your face, philosophy is something that you place in the back seat, assuming your car has a back seat.

But : it isn’t really – when you come up very quickly on the tails of a much less powerful car, and its driver pulls over in fear or irritation, you know you have done the wrong thing, the road is not a race course. That philosophy, Do no harm, is part of the basic principle of driving. 

For most of us driving is a skill. For professionals like cab or truck or bus drivers, it is a craft. I wonder whether professional drivers have developed a sense of art about driving.

But truly, truly, truly, for those who enjoy driving, it is an art, and it has an aesthetic. The aesthetics of the art of driving varies from person to person, car to car, place to place, perhaps even with age and company and music and mindset.
