Isn't shooting first - it's staying focused. Can you be mindful of your environment yet equally focused on a task? That's what driving is, isn't it?
The capacity for intense focus, they note, relies in large part on a brain area called the left ventrolateral prefrontal cortex (VLPFC), which is located a few inches behind the forehead. While this area has been associated with a wide variety of mental talents, like conceptual knowledge and verb conjugation, it seems to be especially important for maintaining attention. Experiments show that neurons in the VLPFC must fire continuously to keep us on task so that we don’t become sidetracked by irrelevant information. Furthermore, deficits in the VLPFC have been associated with attention-deficit disorder.
Several studies found an increase in brain activity (as measured indirectly by blood flow) in the VLPFC of depressed patients. Most recently, a paper to be published next month by neuroscientists in China found a spike in “functional connectivity” between the lateral prefrontal cortex and other parts of the brain in depressed patients, with more severe depressions leading to more prefrontal activity. One explanation for this finding is that the hyperactive VLPFC underlies rumination, allowing people to stay focused on their problem. (Andrews and Thomson argue that this relentless fixation also explains the cognitive deficits of depressed subjects, as they are too busy thinking about their real-life problems to bother with an artificial lab exercise; their VLPFC can’t be bothered to care.) Human attention is a scarce resource — the neural effects of depression make sure the resource is efficiently allocated.
