How far is too far physical boundaries in dating

It was the brain scans she took while people took the test.

Our brains, it turned out, take much longer to develop than we had thought.

This synaptic pruning, as it is called, causes the brain's cortex—the outer layer of gray matter where we do much of our conscious and complicated thinking—to become thinner but more efficient.

Taken together, these changes make the entire brain a much faster and more sophisticated organ.

You view a screen on which the red crosshairs at the center occasionally disappear just as a light flickers elsewhere on the screen.

Your instructions are to not look at the light and instead to look in the opposite direction. It's a tough assignment, since flickering lights naturally draw our attention.

But as we move through adolescence, the brain undergoes extensive remodeling, resembling a network and wiring upgrade.

For starters, the brain's axons—the long nerve fibers that neurons use to send signals to other neurons—become gradually more insulated with a fatty substance called myelin (the brain's white matter), eventually boosting the axons' transmission speed up to a hundred times.But at times, and especially at first, the brain does this work clumsily. Beatriz Luna, a University of Pittsburgh professor of psychiatry who uses neuroimaging to study the teen brain, used a simple test that illustrates this learning curve.Luna scanned the brains of children, teens, and twentysomethings while they performed an antisaccade task, a sort of eyes-only video game where you have to stop yourself from looking at a suddenly appearing light.Although you know your teenager takes some chances, it can be a shock to hear about them. Through the ages, most answers have cited dark forces that uniquely affect the teen.One fine May morning not long ago my oldest son, 17 at the time, phoned to tell me that he had just spent a couple hours at the state police barracks. He did not object when I told him he'd have to pay the fines and probably for a lawyer. My son's high-speed adventure raised the question long asked by people who have pondered the class of humans we call teenagers: What on Earth was he doing? But even that is just another way of wondering, What is wrong with these kids? Aristotle concluded more than 2,300 years ago that "the young are heated by Nature as drunken men by wine." A shepherd in William Shakespeare's The Winter's Tale wishes "there were no age between ten and three-and-twenty, or that youth would sleep out the rest; for there is nothing in the between but getting wenches with child, wronging the ancientry, stealing, fighting." His lament colors most modern scientific inquiries as well. Stanley Hall, who formalized adolescent studies with his 1904 Adolescence: Its Psychology and Its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion and Education, believed this period of "storm and stress" replicated earlier, less civilized stages of human development.The corpus callosum, which connects the brain's left and right hemispheres and carries traffic essential to many advanced brain functions, steadily thickens.
