What Giedd's long-term studies have documented is that there is a second wave of proliferation and pruning that occurs later in childhood and that the final, critical part of this second wave, affecting some of our highest mental functions, occurs in the late teens. Unlike the prenatal changes, this neural waxing and waning alters not the number of nerve cells but the number of connections, or synapses, between them. When a child is between the ages of 6 and 12, the neurons grow bushier, each making dozens of connections to other neurons and creating new pathways for nerve...
...part of the teen-brain story. Right about the time the brain switches from proliferating to pruning, the body comes under the hormonal assault of puberty. (Research suggests that the two events are not closely linked because brain development proceeds on schedule even when a child experiences early or late puberty.) For years, psychologists attributed the intense, combustible emotions and unpredictable behavior of teens to this biochemical onslaught. And new research adds fresh support. At puberty, the ovaries and testes begin to pour estrogen and testosterone into the bloodstream, spurring the development of the reproductive system, causing hair to sprout...
...high-stakes day in the nation's capital that only got more confusing as the hours passed. For a few hours, it looked as if McCain, who came to Washington with the stated goal of helping to hammer out a final deal, had shown up just minutes too late to speed along the once-stalled negotiations. Then McCain, his Democratic rival Barack Obama and congressional leaders from both parties went to the White House for what some billed as a photo-op, a public showing of bipartisan support for a piece of legislation that Federal Reserve Chairman Ben Bernanke, Treasury...
...What it has all come down to is an incredibly high-stakes game of political chicken which no one wants to lose. House Republicans late Thursday were talking up an alternative proposal for the government to help insure the bad mortgage-backed assets rather than buy them up, but that less-expensive option has little support from either Democrats or the Bush Administration. "Members are aware of the crisis situation that we're in," McCain told ABC News Thursday. "They do have concerns, which I think when you're talking about $700 billion or a trillion dollars, that need...
...announcement came Friday morning as Democrats turned up the heat on McCain on cable television, blaming him for throwing a wrench into the talks after a deal - at least between Senators and House Democrats - was largely completed yesterday afternoon. That deal quickly unraveled late yesterday afternoon at an emergency gathering of congressional leaders, McCain and Barack Obama at the White House, where House Republicans voiced their strong opposition to the bailout. Senate Majority Leader Harry Reid seemed to put much of the blame on McCain in a press conference this morning, when he said that the deal's outlines were...
