缺血性脑血管病一直是威胁人类健康的重大疾病之一，减轻缺血造成的脑损害是各国科学家研究的热点。随着对缺血性脑损伤研究的不断深入，人们对其致伤机理有了进一步的了解。实验研究发现，中枢神经系统不同区域中的神经元对缺血的耐受性存在着差异，一些脑区的神经元对缺血较 Ischemic cerebrovascular disease has always been one of the major diseases that threaten human health. It is a hot research topic of scientists in various countries to reduce brain damage caused by ischemia. With the deepening of the research on ischemic brain injury, people have a better understanding of the mechanism of injury. Experimental study found that neurons in different regions of the central nervous system tolerance to ischemia there are differences, some neurons in the brain area of ​​ischemia than
