...Maizan. In Maizan and other districts, Taliban have attacked Afghan police officers and troops, while Coalition soldiers have seen nearly twice as many IEDs, ambushes and mortar attacks this summer as they did for the comparable period last year. For the moment, the Taliban have been reluctant to mount frontal assaults on the Coalition troops in Zabul - "they are afraid of the Romanians' 14 mm machine guns," says McLaughlin - but for how long...
...could still rat you out. Brains require blood to operate, and the harder they work, the more they need. Many regions of the cortex are thought to be recruited for a lie, but three stand out: the anterior (front) cingulate, which reconciles goals and intentions; the right orbital/ interior frontal, which processes the sense of reward; and the right middle frontal, which helps govern tasks requiring more than ordinary thought. Functional magnetic resonance imaging (fMRI) looks for such busy, well-oxygenated areas. Get a hit in all three zones, and you may have a liar. That is what...
...studies based on magnetic resonance imaging (MRI) and basic tape-measure readings, neuroscientist Eric Courchesne at Children's Hospital of San Diego showed that while children with autism are born with ordinary-size brains, they experience a rapid expansion by age 2 - particularly in the frontal lobes. By age 4, says Courchesne, autistic children tend to have brains the size of a normal 13-year-old. This aberrant growth is even more pronounced in girls, he says, although for reasons that remain mysterious, only 1 out of 5 children with autism is female. More recent studies by Amaral and others...
...University of Pittsburgh. Soon after arriving in Iraq he was injured. "We were told by his doctors that the piece of shrapnel had gone under his goggles," says Jeremy?s brother Shaun, "and basically played ping-pong in his head? and he had damage to both sides of his frontal lobe." One tangible memorial to his injuries is a sign near his home: Blind Person Area. A more significant tribute is the work Feldbusch has done in raising awareness of the 19.000 U.S. soldiers wounded in Iraq...
...from one task to another, the toggling action, occurs in a region right behind the forehead called Brodmann's Area 10 in the brain's anterior prefrontal cortex, according to a functional magnetic resonance imaging (fMRI) study by Grafman's team. Brodmann's Area 10 is part of the frontal lobes, which "are important for maintaining long-term goals and achieving them," Grafman explains. "The most anterior part allows you to leave something when it's incomplete and return to the same place and continue from there." This gives us a "form of multitasking," he says, though it's actually...
