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
electrical activity is emanating from the somatosensory neocortex.
llations in brain waves are from hippocampus.
tosensory neocortex and hippocampus work together in memory consolidation.
tosensory neocortex plays it primary role in memory consolidation.
正确答案：C
答案解析：本段告诉我们，科学家分析了老鼠的'脑电波，尤其是从somatosensory neocortex和hippocampus两个区域发出的脑电波。该段是后两句指出，这两个大脑区域的活动是互相作用的。本段并没有说 somatosensory neocortex或 hippocampus起主导作用。
