1、.阅读理解APatients in the early stages of Alzheimers disease often struggle to remember recently learned information, meaning they forget things like important appointments or where they left their keys. But it seems that these memories are not lost. They are still filed away in the brain somewhere; the
2、y just cant be easily accessed.Now, researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimers. The method relies on a technique that uses light to control genetically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it invo
3、lves inserting light emitting(发光) equipment into the subjects brains, but the same principles still apply, the researchers said.“The important point is that this is evidence of the concept. That is, even if a memory seems to be gone, it is still there. Its a matter of how to get it back，”said the se
4、nior researcher Susumu Tonegawa.The team took two groups of mice, one genetically engineered to develop Alzheimers and one healthy. They then placed them into a room and gave them a mild electric shock.All of the mice showed fear when put back an hour later. When placed in the room a third time seve
5、ral days later, the Alzheimers mice acted normally. They had forgotten the shock.The researchers were then able to bring back the memory of the shock by activating(激活) the cells in which the memories were stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells as
6、sociated with the shock were activated.“Shortterm memories seem to be normal in order of hours.But for longterm memories, these earlyAlzheimers mice seem to be damaged，”said the lead researcher Dheeraj Roy.“Directly activating the cells that we believe are holding the memory helps them get it back.
7、This suggests that it is indeed an access problem to the information, not that they are unable to learn or store this memory.”语篇解读本文主要介绍了利用光控制转基因神经元使早老性痴呆病患者恢复记忆的技术。1What can we learn about the researchers at MIT?AThey are the pioneers of brain research.BThey have used the method in human trials.CTh
