Great article by Jonah Lehrer about Geoffrey West and urban metabolism(s).
QUOTE
It’s when West switches the conversation from infrastructure to people that he brings up the work of Jane Jacobs, the urban activist and author of “The Death and Life of Great American Cities.” Jacobs was a fierce advocate for the preservation of small-scale neighborhoods, like Greenwich Village and the North End in Boston. The value of such urban areas, she said, is that they facilitate the free flow of information between city dwellers. To illustrate her point, Jacobs described her local stretch of Hudson Street in the Village. She compared the crowded sidewalk to a spontaneous “ballet,” filled with people from different walks of life. School kids on the stoops, gossiping homemakers, “business lunchers” on their way back to the office. While urban planners had long derided such neighborhoods for their inefficiencies — that’s why Robert Moses, the “master builder” of New York, wanted to build an eight-lane elevated highway through SoHo and the Village — Jacobs insisted that these casual exchanges were essential. She saw the city not as a mass of buildings but rather as a vessel of empty spaces, in which people interacted with other people. The city wasn’t a skyline — it was a dance.

Fascinating article by Jonah Lehrer about depression. Closing paragraphs:
QUOTE
And then there’s the virtue of self-loathing, which is one of the symptoms of depression. When people are stuck in the ruminative spiral, their achievements become invisible; the mind is only interested in what has gone wrong. While this condition is typically linked to withdrawal and silence — people become unwilling to communicate — there’s some suggestive evidence that states of unhappiness can actually improve our expressive abilities. Forgas said he has found that sadness correlates with clearer and more compelling sentences, and that negative moods “promote a more concrete, accommodative and ultimately more successful communication style.” Because we’re more critical of what we’re writing, we produce more refined prose, the sentences polished by our angst. As Roland Barthes observed, “A creative writer is one for whom writing is a problem.”

This line of research led Andrews to conduct his own experiment, as he sought to better understand the link between negative mood and improved analytical abilities. He gave 115 undergraduates an abstract-reasoning test known as Raven’s Progressive Matrices, which requires subjects to identify a missing segment in a larger pattern. (Performance on the task strongly predicts general intelligence.) The first thing Andrews found was that nondepressed students showed an increase in “depressed affect” after taking the test. In other words, the mere presence of a challenging problem — even an abstract puzzle — induced a kind of attentive trance, which led to feelings of sadness. It doesn’t matter if we’re working on a mathematical equation or working through a broken heart: the anatomy of focus is inseparable from the anatomy of melancholy. This suggests that depressive disorder is an extreme form of an ordinary thought process, part of the dismal machinery that draws us toward our problems, like a magnet to metal.

The title is quite misleading since only the first half of Lehrer's article chronicles the city's stressful effects on the brain, while the second half describes urbanism's benefits, and that that it's a question of designing cities so that nature continues to intervene and refresh/ calm / regenerate the brain.

QUOTE:
Given the myriad mental problems that are exacerbated by city life, from an inability to pay attention to a lack of self-control, the question remains: Why do cities continue to grow? And why, even in the electronic age, do they endure as wellsprings of intellectual life?

Recent research by scientists at the Santa Fe Institute used a set of complex mathematical algorithms to demonstrate that the very same urban features that trigger lapses in attention and memory -- the crowded streets, the crushing density of people -- also correlate with measures of innovation, as strangers interact with one another in unpredictable ways. It is the "concentration of social interactions" that is largely responsible for urban creativity, according to the scientists. The density of 18th-century London may have triggered outbreaks of disease, but it also led to intellectual breakthroughs, just as the density of Cambridge -- one of the densest cities in America -- contributes to its success as a creative center. One corollary of this research is that less dense urban areas, like Phoenix, may, over time, generate less innovation.

The key, then, is to find ways to mitigate the psychological damage of the metropolis while still preserving its unique benefits. Kuo, for instance, describes herself as "not a nature person," but has learned to seek out more natural settings: The woods have become a kind of medicine. As a result, she's better able to cope with the stresses of city life, while still enjoying its many pleasures and benefits. Because there always comes a time, as Lou Reed once sang, when a person wants to say: "I'm sick of the trees/take me to the city."

Jonah Lehrer discusses Ed Glaeser's recent post in the NYT blog on NYC and why it's "America's most resilient city." Lots of great points, interesting comments thread, too. Closing line by Lehrer nails it.
