Sleep Lets Brain File Memories
To sleep.Perchance to file?Findings published online this week by the Proceedings of the National
Academy of Science further support the theory that brain organizes and stows memories formed during the day
while the rest of the body is catching zzz's.
Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and
mice.Specifically,they examined the electrical activity emanating from the somatosensory neocortex(an area
that processes sensory information)and the hippocampus,which is a center for learning and memory.The
scientists found that oscillations in brain waves from the two regions appear to be intertwined.So-called sleep
spindles(bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the
hippocampus known as ripples.The team posits that this interplay between the two brain regions is a key
step in memory consolidation.
A second study,also published online this week by the Proceedings of the National Academy of
Sciences,links age-associated memory decline to high glucose level.
Previous research had shown that individuals with diabetes suffer from increased memory problems.In
the new work,Antonio Convit of New York University School of Medicine and his collaborators studied 30
people whose average age was 69 to investigate whether sugar levels,which tend to increase with age,affect
memory in healthy people as well.The scientists administered recall tests,brain scans and glucose tolerance
tests,which measure how quickly sugar is absorbed from the blood by the body's issues.Subjects with the
poorest memory recollection,the team discovered,also displayed the poorest glucose tolerance.In addition,
their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb
blood sugar.
"Our study suggests that this impairment may contribute to the memory deficits that occur as people
age,"Convit says."And it raises the intriguing possibility that improving glucose tolerance could reverse
some age-associated problems in cognition."Exercise and weights control can help keep glucose level in
check,so there may be one more reason to go to the gym.

Text 3Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just “mental noise” -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermostat, regulating moods while the brain is “off-line.” And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep -- when most vivid dreams occur -- as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day.” says Stanford sleep researcher Dr. William Dement.The link between dreams and emotions show up among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events -- until, it appears, we begin to dream.And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time is occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.At the end of the day, there’s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “we waken up in a panic,” Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people’s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep -- or rather dream -- on it and you’ll feel better in the morning.31. Researchers have come to believe that dreams ________.[A] can be modified in their courses[B] are susceptible to emotional changes[C] reflect our innermost desires and fears[D] are a random outcome of neural repairs

共用题干SleepSleep is part of a person's daily activity cycle .There are several different stages of sleep,and they too occur in cycles.______(46)When you first drift off into slumber,your eyes will roll about a bit,your temperature will drop slightly,your muscles will relax,and your breathing will slow and become quite regular. Your brain waves slow down a bit too,with the alpha rhythm of rather fast waves predominating for the first few minutes.______(47)For the next half hour or so,as you relax more and more,you will drift down through stage 2 and stage 3 sleep.______(48)Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all.Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.You do not remain at this deep fourth stage all night long,but instead about 80 minutes after you fall into slumber,your brain activity level will increase again slightly. ______(49)Your eyes will begin to dart around under your closed eyelids as if you were loo-king at something occurring in front of you.______(50)It is during REM sleep period,your body will soon relax again,your breathing will grow slow and regular once more,and you will slip gently back from stage 1 to stage 4 sleep-only to rise once again to the surface of near consciousness some 80 minutes later.______(48)A: The delta rhythm will disappear,to be replaced by the activity pattern of brain waves.B: If you are an average sleeper,your sleep cycle is as follows.C: In stage 4 sleep people tend to dream.D: The lower your stage of sleep,the slower your brain waves will be.E: This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep.F: This is called stage 1 sleep.
共用题干第二篇Exercise and BrainJust as exercise strengthens the heart and lungs,bones and muscles,it may also power up the brain.A succession of scientific studies of animals implies that physical activity has a positive effect on mental functioning."It's clear that the brain benefits from exercise,"says brain scientist William Greenough of the University of Illinois at Urbana-Champaign.His studies with rats have demonstrated two primary effects of activity:Vigorous physical exercise provides the brain with more fuel,and skill-based ex-ercise increases the formation of connections in the brain, which, according to the proposals of some scientists,may make the brain better able to process information.In one experiment,laboratory rats were separated into three groups.One group was exercised by running inside an automatic wheel,a second group improved their skills in a complicated obstacle course,and a third group was inactive."The animals that learned to go through the obstacle course exhibited a greater number of brain connections than the animals in the exercised or inactive groups,"Greenough said."In contrast, the animals that exercised inside the automatic wheel possessed a greater density of blood vessels in the brain than did either of the other two groups of animals."Learning a new dance step may boost the brain in the same way that learning a language can, he says.And if the dance is a good physical exercise as well,the benefits multiply.Young brains may be especially able to boost brain power through exercise,suggested another of Greenough's experiments that showed the most significant changes in the brain occurred among rats that had been exercised when very young.And while animals aren't people,he says it is logical to make the inference that an effect found in rats may also apply to humans.Human studies have focused primarily on older adults and suggest that regular exercise can improve the speed with which the brain processes information.Measurements made by Arthur Kramer at the University of Illinois demonstrated that inactive adults,aged 63 to 82,could hit buttons faster in response to a tone after they went through a 10-week water exercise course.A corresponding control group that didn't exercise showed no improvement.Vigorous physical exercise can________.A:provide the brain with more fuelB:increase the formation of connections in the brainC:make the brain better able to process informationD:do nothing good to our brain
共用题干Young Adults Who Exercise Get Higher IQ ScoresYoung adults who are fit have a higher IQ and are more likely to go on to university,reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.The results were recently published in the Proceedings of the National Academy of Sciences (PNAS)The study involved 1 .2 million Swedish men doing military service who were born be-tween 1950 and 1976 .The research group analyzed the results of both physical and IQ tests the youngsters took right after they started serving the army.The study shows a clear link between good physical fitness and better results for the IQ test. The strongest links are for logical thinking and verbal comprehension.But it is only fitness that plays a role in the results for the IQ test,and not strength.“Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen,”says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. “This may be one of the reasons why we can see a clear link with fitness,but not with muscular strength .We are also seeing that there are growth factors that are important.”By analyzing data for twins,the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and higher IQ.“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Maria Aberg,researcher at the Sahl-grenska Academy and physician at Aby health centre.“This being the case,physical education is a subject that has an important place in schools,and is an absolute must if we want to do well in maths and other theoretical subjects.”The researchers have also compared the results from fitness tests during national service with the socio-economic status of the men later in life.Those who were fit at 18 were more likely to go into higher education,and many secured more qualified jobs.Which of the following is an implication of physical fitness?A: Brain size.B: Good logical capacity.C: Clear logical thinking.D: Muscular strength.

The database is being restored from a closed backup. The data files， control files， password file， and parameter file are available， but the online redo logs are not. Because the online redo logs are not available， you must simulate recovery and alter the database open with the reset logs option so the online redo logs are created while the database opens. Which type of recover is used in this situation？（）A、until SCNB、until timeC、until cancelD、using backup control file
You are the network administrator for TestKing. The network contains a Windows Server 2003 computer named Testking1. You back up the data folders on Testking1 by using the following schedule: 1. Normal backup every Monday. 2. Incremental backups every Tuesday, Wednesday, Thursday, and Friday. After the backup on Friday is completed, a user accidentally deletes a file from a data folder on Server1. The user reports that he modified the file in the past week, but he does not know which day he modified the file. You do not know when the file was last backed up. You need to restore the latest copy of the file as quickly as possible. What should you do?（）A、Open the backup log for each day. Begin by opening the log for Monday, and then work forward through the logs for each day of the week. In each log, search for a backup of the file. Restore the first backup that you find.B、Open the backup log for each day. Begin by opening the log for Tuesday, and then work forward through the logs for each day of the week. In each log, search for a backup of the file. Restore the first backup that you find.C、Open the backup log for each day. Begin by opening the log for Friday, and then work backward through the logs for each day of the week. In each log, search for a backup of the file. Restore the first backup that you find.D、Restore the file from the Monday, Tuesday, Wednesday, Thursday, and Friday backups, in that order.E、Restore the file from the Monday backup, and then from the Friday backup.
