　　5、[閱讀理解]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 levels.

　　What is the result of the experiment with rats and mice carried out at Rutgers University

　　A、The electrical activity is emanating from the somatosensory neocortex.

　　B、Oscillations in brain waves are from hippocampus.

　　C、Somatosensory neocortex and hippocampus work together in memory consolidation.

　　D、Somatosensory neocortex plays it primary role in memory consolidation.

　　正確答案：C

　　答案解析：答案選C。本段告訴我們，科學(xué)家分析了老鼠的腦電波，尤其是從somatosensory neocortex和hippocampus兩個(gè)區(qū)域發(fā)出的腦電波。該段是后兩句指出，這兩個(gè)大腦區(qū)域的活動(dòng)是互相作用的。本段并沒有說 somatosensory neocortex或 hippocampus起主導(dǎo)作用。

While the one protects the individual from violence， the other sacrifices the individual to violence in the interests of the state.
