...your kidneys, to start pumping out cortisol, which acts as a wake-up signal. Cortisol levels continue to rise after you become conscious in what is sometimes referred to as the "Oh, s___! It's another day" response. This may help explain why so many heart attacks and strokes occur between...
Here's how the experiment works: if you provide mice with an escape route, they typically learn very quickly how to avoid a mild electrical shock that occurs a few seconds after they hear a tone. But if the escape route is blocked whenever the tone is sounded, and new shocks occur, the mice will eventually stop trying to run away. Later, even after the escape route is cleared, the animals simply freeze at the sound of the tone--despite the fact that they once knew how to avoid the associated shock...
...SCIENTISTS PROBE the limits of neuroplasticity, they are finding that mind sculpting can occur even without input from the outside world. The brain can change as a result of the thoughts we think, as with Pascual-Leone's virtual piano players. This has important implications for health: something as seemingly insubstantial as a thought can affect the very stuff of the brain, altering neuronal connections in a way that can treat mental illness or, perhaps, lead to a greater capacity for empathy and compassion. It may even dial up the supposedly immovable happiness set point...
...this does not mean we cannot use the 21,500 troops. During the next two years, Iraq's breakup will occur with or without us. Baghdad will inexorably fall to the Shi'a. "They get the big bonanza," as one Sunni bitterly put it. Anbar, Ramadi, Fallujah and much of the upper Euphrates Valley are practically a solid Sunni green now. There are still mixed towns and provinces here and there, but it's just a matter of time before their minorities pick up and leave for the security of their...
...were to withdraw today, the breakup would occur a lot faster, maybe over a few months, but blood would flow in rivers. The chances Saudi Arabia and Iran would be pulled in is almost certain. Even more refugees would flow into Jordan and Syria, destabilizing them. To be sure, extra American troops will not completely stop the violence, but it will tamp it down to permit a more or less peaceful relocation...
