研究人员发现,宇航员的大脑形状在太空中会发生改变。密歇根大学的科学家们对近期在国际空间站工作过的宇航员大脑进行了功能性磁共振扫描,结果发现部分脑区的灰质减少,其它部分则灰质增多。该研究将有助于治疗其它影响大脑的疾病,如长期卧床病人易患的脑水肿等。研究人员分析了12名在航天飞机上待过两周的宇航员以及14名在国际 Researchers have found that the astronaut’s brain shape changes in space. Scientists at the University of Michigan conducted a functional magnetic resonance scan of the astronauts’ brain that recently worked on the ISS and found that gray matter was reduced in some areas of the brain and gray matter was increased in other areas. The study will help treat other diseases that affect the brain, such as long-term bedridden patients prone to brain edema. Researchers analyzed 12 astronauts who spent two weeks on the shuttle and 14 at the International
