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...

When your opponent is answering, you tend to think you're off camera. But you're not. If you scowl...
...statement added that McCain would return to Washington after the debate "to ensure that all voices and interests are represented in the final agreement, especially those of taxpayers and homeowners." It also lamented the "familiar spectacle in Washington" and attacked Obama directly: "The difference between Barack Obama and John McCain was apparent during the White House meeting yesterday where Barack Obama's priority was political posturing in his opening monologue defending the package as it stands. John McCain listened to all sides so he could help focus the debate on finding a bipartisan resolution that is in the interest...
