A good run can sometimes make you feel like a brand-new person. And, in a way, that feeling may be literally true. About three decades of research in neuroscience have identified a robust link between aerobic exercise and subsequent cognitive clarity, and to many in this field the most exciting recent finding in this area is that of neurogenesis. Not so many years ago, the brightest minds in neuroscience thought that our brains got a set amount of neurons, and that by adulthood, no new neurons would be birthed. But this turned out not to be true.【B11】______________
The other fascinating thing is where these new cells pop up.【B12】______________If you are exercising so that you sweat—about 30 to 40 minutes—new brain cells are being born," added Postal, who herself is a runner. "And it just happens to be in that memory area."
Other post-run changes have been recorded in the brain’s frontal lobe.【B13】____________After about 30 to 40 minutes of a vigorous aerobic workout—enough to make you sweat—studies have recorded increased blood flow to this region, which, incidentally, is associated with many of the attributes we associate with "clear thinking": planning ahead, focus and concentration, goal-setting, time management.
【B14】_____________________Mindfulness, or being here now, is a wonderful thing, and there is a seemingly ever-growing stack of scientific evidence showing the good it can bring to your life. And yet mindlessness—daydreaming, or getting lost in your own weird thoughts—is important, too.
【B15】___________________For example, having to reread a line of text three times because our attention has drifted away matters very little if that attention shift has allowed us to access a key insight, a precious memory or make sense of a troubling event; pausing to reflect in the middle of telling a story is inconsequential if that pause allows us to retrieve a distant memory that makes the story more compelling; and arriving home from the store without the eggs that necessitated the trip is a mere annoyance when weighed against coming to a decision to ask for a raise, leave a job, or go back to school.
[A] There’s another big mental benefit to gain from running, one that scientists haven’t quiet yet man-aged to pin down to poke at and study: the wonderful way your mind drifts here and there as the miles go by.
[B] But it’s this area that’s also been linked to emotion regulation, which may help explain the results of one recent study conducted by Harvard psychology PhD candidate Emily E. Bernstein.
[C] Studies in animal models have shown that new neurons are produced in the brain throughout the lifespan, and, so far, only one activity is known to trigger the birth of those new neurons: vigorous aerobic exercise, said Karen Postal, president of the American Academy of Clinical Neuropsychology.
[D] Intervention studies have popped up in recent years that suggest if you can get people who are having trouble with mood or anxiety to exercise, it helps.
[E] This area of the brain—also called the frontal executive network system—is located, obviously enough, at the very front: It’s right behind your forehead. Increased activity happens in this region after people adopt a long-term habit of physical activity.
[F] This insight can be better illustrated by the fact that mind-wandering, by choice or by accident, pro-duces tangible reward when measured against goals and aspirations that are personally meaningful.
[G] It’s in the hippocampus, a region of the brain associated with learning and memory. So this could help explain, at least partially, why so many studies have identified a link between aerobic exercise and improvement in memory.
【B13】
选项
答案
E
解析
空格前提到跑步也会让大脑额叶发生变化,下文应该会接着介绍具体是什么变化。E先对大脑某个区域做介绍,根据介绍的特征——位于大脑非常靠前的地方(frontal、front、forehead),可知此处讲的应是上文的frontal lobe,是对这个术语的解释说明。E末句指出当人们养成长期运动的习惯之后,这个区域的活性就会增加;这既对应的是空格前的Other post-run changes,也与空格后说的increased blood flow相符,故本题选E。
