WASHINGTON - Scientists are gaining new insights into remarkable changes in teenagers' brains that may help explain why the teen years are so hard on young people - and on their parents.
From ages 11 to 14, a young person loses a substantial fraction of the connections between cells in the part of the brain that enable him or her to think clearly and make good decisions. This loss is a vital part of growing up. It clears out, or "prunes," unneeded wiring to make way for more efficient information-processing in adults.
"Ineffective or weak connections are pruned in much the same way a gardener would prune a tree or bush, giving the plant the desired shape," said Alison Gopnik, a professor of child development at the University of California-Berkeley.
The pruning process "appears to follow the principle of use-it-or-lose-it," said Jay Giedd, a child development expert at the National Institute of Mental Health, in Bethesda, Md. "Neural connections or synapses that get exercised are retained, while those that don't are lost."
Like teenage pimples and body hair, changes inside the head can be upsetting.
"It certainly seems possible that normal adolescents who are experiencing these brain changes can react emotionally," said Ian Campbell, a neuroscientist at the University of California-Davis Sleep Research Laboratory.
"Teens may process emotions differently than adults," said Giedd, who calls the teenage brain "a work in progress."
Girls typically start pruning their brain cells about a year before boys do, but the loss ends up the same, Campbell said.
To figure out why teenagers are often moody, uncooperative and irresponsible, scientists make images of their brains. Their tools include electroencephalograms, which record brain waves, and functional magnetic resonance imaging, which measures activity in various regions of the brain.
"In the past decade, brain changes in adolescence have become the subject of intensive research," Campbell said.
For instance, he and a colleague at the University of California-Davis, psychiatrist Irwin Feinberg, attached EEG recorders to the skulls of two groups of children - one of 9- to 11-year-olds, the other of 12- to 14-year-olds - while they slept. The devices showed that the brain waves were 25 percent weaker in the older children than in the younger ones, the scientists reported in the December issue of the American Journal of Physiology.
These waves are produced by electrical vibrations in brain cells, or neurons. The more neurons vibrate in concert, the stronger the wave.
Campbell compared the effect to "crowd noise within a stadium. When all the members of the crowd yell together, the noise is very loud." Similarly, in the brain, he said, "the intensity is strongly affected by the number of neurons oscillating in unison."
Synaptic pruning is a good thing. It brings about "an improvement in speed in information-processing and a greater ability to build the long neuronal chains required for complex problem-solving," Campbell said. "There are situations in which less is more."
However, the loss of synapses makes it much harder for an adult to learn a new language without a foreign accent or to achieve first-class athletic or musical skills.
According to Gopnik's book, "The Scientist in the Crib," each neuron in the cerebral cortex, the front part of the brain, where higher-level thinking is centered, has about 2,500 connections, known as synapses, at birth. By the age of 2 or 3, the number has soared to about 15,000 synapses per neuron. Eventually, however, as a result of synaptic pruning, the average adult brain has only half as many connections. Alzheimer's patients have even fewer.
Other crucial changes occur in the teenage brain parallel with pruning. According to Giedd, "a major rearrangement of brain structure and function takes place during early adolescence."
Regions that specialize in language, for example, grow rapidly until about age 13 and then stop. The frontal lobes of the brain, which are responsible for high-level reasoning and decision-making, aren't fully mature until adulthood, around the early 20s, according to Deborah Yurgelun-Todd, a neuroscientist at Harvard's Brain Imaging Center in Belmont, Mass.
"Adolescents are more prone to react with gut instinct when they process emotions," Yurgelun-Todd said. "But as they mature into early adulthood, they are more able to temper their gut reactions with reasoned responses."
This is why some researchers, such as Abigail Baird, a psychologist at Vassar College in Poughkeepsie, N.Y., contend that teenage criminals shouldn't be subject to the death penalty.
"These studies have shown remarkable changes that occur in the brain during the teen years, Giedd said. "They also demonstrate what every parent can confirm: The teenage brain is a very complicated and dynamic area, one that is not easily understood."

|Teenage Risks, and How to Avoid
NY Times, December 18, 2007
By Jane E. Brody
Last January in Freehold Township, N.J., a car driven by a 17-year-old high school student, with two fellow students as passengers, passed a car being driven by another teenager at 70 miles an hour in a 50-mile zone. The passing vehicle crashed into an oncoming van. Three boys and the 68-year-old van driver were killed.
It is an all too familiar tale, prompting parents and school officials alike to wonder why risky behavior is so common among teenagers and what might be done to curtail it. Is it that teenagers think that they are immortal or invulnerable, immune to the hazards adults see so clearly? Or do they not appreciate the risks involved and need repeated reminders of the dangers inherent in activities like driving too fast, driving drunk, having unprotected sex, experimenting with drugs, binge drinking, jumping into unknown waters, you name it?
None of the above, says Valerie F. Reyna, professor of human development and psychology at the New York State College of Human Ecology at Cornell. The facts are quite the opposite. Scientific studies have shown that adolescents are very well aware of their vulnerability and that they actually overestimate their risk of suffering negative effects from activities like drinking and unprotected sex.
For example, a study by researchers at the University of California, San Francisco, found that teenagers were more likely than adults to overestimate risks for every outcome studied, from low-probability events like contracting H.I.V. to higher-probability ones like acquiring more common sexually transmitted diseases or becoming pregnant from a single act of unprotected sex.
“We found that teenagers quite rationally weigh benefits and risks,” Dr. Reyna said in a recent interview. “But when they do that, the equation delivers the message to go ahead and do that, because to the teen the benefits outweigh the risks.”
For example, she said: “The risk of pregnancy from a single act of unprotected sex is quite small, perhaps one chance in 12, and the risk of contracting H.I.V., about one in 500, is very much smaller than that. We’re not thinking logically; they are.”
For that reason, Dr. Reyna and Frank Farley, a professor at Temple University and past president of the American Psychological Association, noted last June in an article in Scientific American Reports that traditional programs that appeal to teenagers’ rationality “are inherently flawed, not because teens fail to weigh risks against benefits,” but because “teens tend to weight benefits more heavily than risks when making decisions.”
As for perceptions of invulnerability, a national study of 3,544 teenagers a decade ago found that their own estimates of their risk of dying were very much higher than the actual risk. Because adolescents already feel so vulnerable, showing them photos or films of fatal car crashes may do nothing to reduce future risk-taking.
“It now becomes clearer why traditional intervention programs fail to help many teenagers,” Dr. Reyna and Dr. Farley wrote. “Although the programs stress the importance of accurate risk perception, young people already feel vulnerable and overestimate their risks.”
In Dr. Reyna’s view, inundating teenagers with factual risk information could backfire, leading them to realize that behaviors like unprotected sex are less risky than they thought. Using an analytical approach of weighing risks versus benefits is “a slippery slope that all too often results in teens’ thinking that the benefits outweigh the risks,” she said.
A New Strategy
Based on what she and others have learned about how teenagers react to risky choices, Dr. Reyna, co-director of the Center for Behavioral Economics and Decision Research at Cornell, and her colleague Charles J. Brainerd are testing a new approach to adolescent risk prevention.
She explained that as people grew older and more experienced, they became more intuitive, and more of their decisions were based on what she calls “gist,” an overall sense of what is the best course of action.
This approach, in which “one sees the forest more than the trees,” enables adults to reach the bottom line more quickly and, in the process, reduce their risky behaviors.
For example, while an adolescent might consider playing Russian roulette for a $1 million payoff, a normal adult would not give it a moment’s thought. Cutting directly to the chase, the adult would be more inclined to think: “No way! No amount of money is worth a one in six chance of dying.”
“Young people don’t get it,” Dr. Reyna said. “They don’t get the gist of a situation. Gist is based on one’s culture, background and experiences, and experience is what teens lack.”
A gist-based approach to decision making results in simple, black-and-white conclusions of good or bad, safe or dangerous, she and Dr. Farley wrote.
How can “gist” be created? After a young woman I knew became a paraplegic after swerving her car to avoid hitting a squirrel, I trained myself mentally not to brake or swerve in that situation, and I urged my sons and daughters-in-law to do the same. The gist here is that the life of a squirrel is not worth the possible consequences to me or anyone else on the road.
Likewise, in helping a teenage girl resist spontaneous, unprotected sex, a gist-based approach has her practicing ways to say “no” and not worry about losing her boyfriend. A 15-year-old who already had one unintended pregnancy and who participated in the “intuitive, gist-enhanced intervention program” that Dr. Reyna and Dr. Farley devised put it this way: “In talking about all the different ways to say ‘no,’ I’ve actually used them, which makes me feel much more comfortable. And I feel confident. I don’t feel stupid by saying ‘no.’ And even if people think I’m stupid, that’s their problem.”
Making Good Choices
Teenagers need “practice at recognizing cues in the environment that signal possible danger before it’s too late to act,” the two experts urged in a 44-page review of adolescent decision making published in September 2006 in the journal Psychological Science in the Public Interest.
At the same time, Dr. Reyna warned: “Younger adolescents don’t learn from consequences as well as older adolescents do. So rather than relying on them to make reasoned choices or to learn from the school of hard knocks, a better approach is to supervise them.”
In other words, young teenagers need to be protected from themselves by removing opportunities for risk-taking — for example, by filling their time with positive activities and protecting them from risky situations that are likely to be tempting or that require “behavioral inhibition.”
A young teenage girl should not be left alone in the house with her boyfriend, and responsible adults should be omnipresent and alcohol absent when teenagers have parties.
