A model of cerebral ischemia by microsphere embolization in the rabbit was monitored with somatosensory evoked potentials by median nerve stimulation (SEPs) and by flash visual evoked potential (VEPs). The degree of SEP alterations paralleled the type of lesions (focal or multifocal ischemia or diffuse oedema). Alterations present at the first hour after ischemia were generally unchanged during the follow-up, which ended at the 24th hour. The prevalence of VEP alterations was low (only 16% in focal ischemia). These results are compared to EEG modifications performed in the same animals.
通过对兔正中神经刺激的体感诱发电位（SEPs）和闪光视觉诱发电位（VEPs）监测微球栓塞所致兔脑缺血模型。SEP改变的程度与病变类型（局灶性或多灶性缺血或弥漫性水肿）平行。缺血后第1小时出现的改变在随访期间（至第24小时结束）通常无变化。VEP改变的发生率较低（局灶性缺血中仅16%）。将这些结果与在相同动物中进行的脑电图改变进行比较。
