Females have more comlex brain structure
10/04/2004 12:43

Researcher Eilin Ludes from the Frankfurt University studied brain pictures of 30 people of both sexes and arrived at a conclusion that female brain structure implies better thinking abilities and connection between neurons.

According to the researcher, female brain contains 20 per cent more grey matter as compared with that of male's, its neurons are closer to each other. Eilin Ludes explains the phenomenon with the fact that female brain is confined within a smaller cranium than men's, that is why the structure of female brain is more complicated thanks to better internal development.

Russian scientists are rather skeptical about the statement. Lecturer from the Vinnitsa Medicine University Sergey Grishchenko says a group of 30 people is not enough for such an experiment. It requires examination of hundreds or thousands of patients to arrive to any important conclusion. What is more he adds, there is no notion of "complicated brain convolutions". Male and female brains do not differ on the surface, as well as other organs with the exception of genitals.

The Russian lecturer insists neither amount nor shape of brain convolutions determine man's intellectual faculties. They do depend upon inter-neuron connections that form during a man's life. Doctor of medical science Professor Pavel Shaparenko says female brain is a bit bigger proportionally than that of a man.

Average weight of male brain is 1.375g and of female brain - 1.275g. By the way, a man with the biggest brain ever registered (2.222g) was in fact just an ordinary person.

Revenge of the Right Brain
By Daniel H. Pink


Logical and precise, left-brain thinking gave us the Information Age. Now comes the Conceptual Age - ruled by artistry, empathy, and emotion.

When I was a kid - growing up in a middle-class family, in the middle of America, in the middle of the 1970s - parents dished out a familiar plate of advice to their children: Get good grades, go to college, and pursue a profession that offers a decent standard of living and perhaps a dollop of prestige. If you were good at math and science, become a doctor. If you were better at English and history, become a lawyer. If blood grossed you out and your verbal skills needed work, become an accountant. Later, as computers appeared on desktops and CEOs on magazine covers, the youngsters who were really good at math and science chose high tech, while others flocked to business school, thinking that success was spelled MBA.

Tax attorneys. Radiologists. Financial analysts. Software engineers. Management guru Peter Drucker gave this cadre of professionals an enduring, if somewhat wonky, name: knowledge workers. These are, he wrote, "people who get paid for putting to work what one learns in school rather than for their physical strength or manual skill." What distinguished members of this group and enabled them to reap society's greatest rewards, was their "ability to acquire and to apply theoretical and analytic knowledge." And any of us could join their ranks. All we had to do was study hard and play by the rules of the meritocratic regime. That was the path to professional success and personal fulfillment.

But a funny thing happened while we were pressing our noses to the grindstone: The world changed. The future no longer belongs to people who can reason with computer-like logic, speed, and precision. It belongs to a different kind of person with a different kind of mind. Today - amid the uncertainties of an economy that has gone from boom to bust to blah - there's a metaphor that explains what's going on. And it's right inside our heads.

Scientists have long known that a neurological Mason-Dixon line cleaves our brains into two regions - the left and right hemispheres. But in the last 10 years, thanks in part to advances in functional magnetic resonance imaging, researchers have begun to identify more precisely how the two sides divide responsibilities.  The left hemisphere handles sequence, literalness, and analysis. The right hemisphere, meanwhile, takes care of context, emotional expression, and synthesis. Of course, the human brain, with its 100 billion cells forging 1 quadrillion connections, is breathtakingly complex. The two hemispheres work in concert, and we enlist both sides for nearly everything we do. But the structure of our brains can help explain the contours of our times.

Until recently, the abilities that led to success in school, work, and business were characteristic of the left hemisphere. They were the sorts of linear, logical, analytical talents measured by SATs and deployed by CPAs. Today, those capabilities are still necessary. But they're no longer sufficient.  In a world upended by outsourcing, deluged with data, and choked with choices, the abilities that matter most are now closer in spirit to the specialties of the right hemisphere - artistry, empathy, seeing the big picture, and pursuing the transcendent.

Beneath the nervous clatter of our half-completed decade stirs a slow but seismic shift.  The Information Age we all prepared for is ending. Rising in its place is what I call the Conceptual Age, an era in which mastery of abilities that we've often overlooked and undervalued marks the fault line between who gets ahead and who falls behind.

To some of you, this shift - from an economy built on the logical, sequential abilities of the Information Age to an economy built on the inventive, empathic abilities of the Conceptual Age - sounds delightful. "You had me at hello!" I can hear the painters and nurses exulting. But to others, this sounds like a crock. "Prove it!" I hear the programmers and lawyers demanding.

OK. To convince you, I'll explain the reasons for this shift, using the mechanistic language of cause and effect.

The effect: the scales tilting in favor of right brain-style thinking. The causes: Asia, automation, and abundance.

Asia

Few issues today spark more controversy than outsourcing. Those squadrons of white-collar workers in India, the Philippines, and China are scaring the bejesus out of software jockeys across North America and Europe. According to Forrester Research, 1 in 9 jobs in the US information technology industry will move overseas by 2010. And it's not just tech work. Visit India's office parks and you'll see chartered accountants preparing American tax returns, lawyers researching American lawsuits, and radiologists reading CAT scans for US hospitals.

The reality behind the alarm is this: Outsourcing to Asia is overhyped in the short term, but underhyped in the long term. We're not all going to lose our jobs tomorrow. (The total number of jobs lost to offshoring so far represents less than 1 percent of the US labor force.) But as the cost of communicating with the other side of the globe falls essentially to zero, as India becomes (by 2010) the country with the most English speakers in the world, and as developing nations continue to mint millions of extremely capable knowledge workers, the professional lives of people in the West will change dramatically. If number crunching, chart reading, and code writing can be done for a lot less overseas and delivered to clients instantly via fiber-optic cable, that's where the work will go.

But these gusts of comparative advantage are blowing away only certain kinds of white-collar jobs - those that can be reduced to a set of rules, routines, and instructions.  That's why narrow left-brain work such as basic computer coding, accounting, legal research, and financial analysis is migrating across the oceans. But that's also why plenty of opportunities remain for people and companies doing less routine work - programmers who can design entire systems, accountants who serve as life planners, and bankers expert less in the intricacies of Excel than in the art of the deal. Now that foreigners can do left-brain work cheaper, we in the US must do right-brain work better.

Last century, machines proved they could replace human muscle. This century, technologies are proving they can outperform human left brains - they can execute sequential, reductive, computational work better, faster, and more accurately than even those with the highest IQs. (Just ask chess grandmaster Garry Kasparov.)

Consider jobs in financial services. Stockbrokers who merely execute transactions are history. Online trading services and market makers do such work far more efficiently. The brokers who survived have morphed from routine order-takers to less easily replicated advisers, who can understand a client's broader financial objectives and even the client's emotions and dreams.

Or take lawyers. Dozens of inexpensive information and advice services are reshaping law practice. At CompleteCase.com, you can get an uncontested divorce for $249, less than a 10th of the cost of a divorce lawyer. Meanwhile, the Web is cracking the information monopoly that has long been the source of many lawyers' high incomes and professional mystique. Go to USlegalforms.com and you can download - for the price of two movie tickets - fill-in-the-blank wills, contracts, and articles of incorporation that used to reside exclusively on lawyers' hard drives. Instead of hiring a lawyer for 10 hours to craft a contract, consumers can fill out the form themselves and hire a lawyer for one hour to look it over. Consequently, legal abilities that can't be digitized - convincing a jury or understanding the subtleties of a negotiation - become more valuable.
