Brain Development

Scientists have figured out how to grow human stem cells into "cerebral organoids" - blobs of tissue that mimic the anatomy of the developing brain. The advance, reported online Wednesday by the journal Nature, won't allow scientists to grow disembodied brains in laboratory vats, said study leader Juergen Knoblich, a stem cell researcher at the Institute of Molecular Biotechnology of the Austrian Academy of Science in Vienna. But it does offer researchers an unprecedented view of human brain anatomy, he said.

Taking a common class of antidepressants called serotonin reuptake inhibitors, or SRIs, during pregnancy alters the developmental time-course of the child's language processing, according to a new study published Monday in the Proceedings of the National Academy of Sciences. While the results are striking, they hardly suggest the practice should be stopped: The researchers found that the children of women who are depressed while pregnant and who do not take medication are also born with an altered course of development.

ARITHMETIC flashcards at the age of 3 won't unleash the next Einstein. Nor will choosing a precise combination of educational toys guarantee a future good job and happy life. It's attention and play with adoring adults that stimulates brain development -- not just in individual infants, but in the nation's future workforce.

As the dramatic abortion debate plays out in courtrooms and legislatures across the nation, a basic and vitally important question arises ever more insistently--when does human life begin? The Roman Catholic Church claims conception is life's starting point, whereas most current abortion laws are keyed to when the fetus might survive if born prematurely (at the end of the second trimester).

In a finding that points to a link between environmental toxins and autism, a new study shows that children who were exposed to the highest levels of traffic-related air pollution during gestation and in early infancy were three times more likely to be diagnosed with the neurodevelopmental disorder than were those whose early exposure to such pollutants was very low. The study , published Monday in the Archives of General Psychiatry, found that...

Slow down when you speak. That’s advice not just for children who stutter but for their parents too. Being more relaxed in your own speech helps a stutterer more than telling them to "try it again slowly. " The tip comes from the Stuttering Foundation , which marks International Stuttering Awareness Day on Friday. The goal is to spread the word about early intervention, reports the Newport News Daily Press blog Health Notes . Not every kid who stutters will do so for the rest of his or her life.

Perhaps there's an explanation after all for why some teenagers are so notoriously difficult: Their minds cannot yet fully reason. Government researchers found in a recent study that the last areas of the brain to mature in humans appear to be those responsible for reasoning, problem-solving and other sophisticated functions. This doesn't happen until sometime between the ages of 18 and 21. The findings come from researchers at the National Institute of Mental Health in Bethesda, Md.

Although the fetus weighs well under a pound, the major organs and systems of the body are formed by the end of the first trimester. MONTH ONE The embryo develops a simple brain, spine and central nervous system. Weeks 3-8: Greatest sensitivity to teratogens. Week 4: The skin cells begin to form in two layers. MONTH TWO Week 5: Fetal cells in mother's blood can be used to identify birth defects. The heart is less than a half-inch in diameter and begins to beat.

"Teenagers are often impulsive. " That's the opening sentence of a new scientific paper. Raise your hand if you're a parent of an adolescent and agree. Impulsivity is a major focus on researchers studing the brain and human behavior because being overly impulsive or a risk-taker or dare-devil is linked to more problems in life. Kids who can't seem to control their impulses make bad decisions: like swallowing a mysterious pill someone brought to school or riding on a skateboard attached to a car. They are driven by a need for instant gratification and fail to consider the long-term consequences of their actions.

Nothing gets our attention like pain. But pain is more than the body's miniature cattle prod to get us to heed a wound, rest a swollen ankle, or stop eating chili peppers. Pain may be the language between animals and microbes. Far from being a product of an inflamed immune system, aggravated nerves far from the spine and brain appear to communicate with invading bacteria and regulate the fight against them, according to a study published online Wednesday in the journal Nature.
