在机体的所有器官中,中枢神经系统对低氧最敏感,低氧可引起脑功能障碍,如记忆、行为、情绪等高级功能障碍,但机制尚不清楚。为此,作者利用低压缺氧模型,探讨大鼠学习记忆行为的改变以及与海马ＧＡＢＡ含量的关系。结果发现,正常对照组大鼠在自动爬杆主动回避反应(ＡＡＲ)习得训 In all organs of the body, the central nervous system is the most sensitive to hypoxia. Hypoxia can cause brain dysfunction such as advanced dysfunction of memory, behavior and emotion, but the mechanism is still not clear. To this end, the author uses hypobaric hypoxia model to explore the changes of learning and memory behavior and the relationship with the content of GABA in hippocampus. The results showed that the normal control group rats in automatic climbing pole active avoidance response (AAR) learned training
