大鼠局部脑缺血再灌注（IR）同侧缺血区、半暗区结构和功能的异常已引起人们的重视[1]，但非缺血区结构与功能是否发生异常尚未见报道。本文在实验[2～4]基础之上，就缺血侧对非缺血侧皮层电活动的影响进行了初步的探讨。材料和方法一、Wistar雄性健康大鼠18只，体重323±19g（
Abnormal ischemic and semi-dark zone structures and functions in focal cerebral ischemia-reperfusion (IR) rats have drawn much attention [1]. However, the abnormality of the structure and function of non-ischemic areas has not been reported yet. Based on the experiments [2 ~ 4], this paper discussed the effect of ischemia on the non-ischemic cortical electrical activity. Materials and methods First, 18 Wistar male healthy rats weighing 323 ± 19g (
