Insomniacs(someone who cannot sleep easily)don’t just suffer at night. During the day, they often feel sleepy, have trouble concentrating and report greater difficulty with work or school performance than individuals who get adequate sleep.
But researchers are intrigued by an apparent【C1】______: Despite what insomnia patients experience subjectively, they often seem able to【C2】______cognitive tasks as well as people getting adequate sleep.
One【C3】______is that insomnia doesn’t lead to【C4】______performance after all—maybe it just feels that way.
Using brain imaging technology, researchers【C5】______25 people with insomnia and 25 normal sleepers as they performed an eight-minute working-memory task【C6】______the processing and storing of short-term memory.
As the exercises became more difficult, the people who sleep【C7】______had increased activity in parts of the brain【C8】______the insomnia subjects didn’t. And the poor sleepers couldn’t turn off the brain’s "mind wandering" regions, also known as the "【C9】______mode" network, located generally【C10】______the brain’s midline. These regions are ordinarily active when a person isn’t【C11】______in goal-directed behavior and they are【C12】______when the person switches to a task.
The more the insomnia patients subjectively reported【C13】______and difficulty concentrating, and the【C14】______they subjectively reported performing their task, the greater was their【C15】______to turn off the mind wandering regions, as measured by the MRI. "There’s no doubt that what’s going on in the brain could be measured as less【C16】______," experts said.
More research is needed to understand how insomnia patients were able to【C17】______and perform the tasks equally well despite the apparent【C18】______in brain activity. The ultimate goal of this kind of research is to【C19】______the environmental and genetic causes of insomnia and develop【C20】______treatments.
【C18】
选项
A、breakdown
B、disfunction
C、discrimination
D、distraction
答案
B
解析
空格前的despite提示,the apparent——in brain activity与上文perform thetasks equally well是相对立的,应是消极的。结合上文提及失眠症患者的“心不在焉”区很难关闭,可知这属于大脑活动的一种机能失常。故选B项disfunction“功能紊乱”。
