ABR was measured ipsilaterally following permanent left anterior inferior cerebellar artery (AICA) occlusion to assess the discrepancy in recovery between blood flow and function in the rat brainstem. Three types of wave patterns were classified: in type 1, all components disappeared: in type 2, all components disappeared transiently, then re-appeared; and in type 3, only a significant increase in the latency difference between components I-IV was noted. In type 2, we suggest that all components re-appeared because cochlear blood flow was re-established quickly by collateral circulation.
在永久性左侧小脑前下动脉（AICA）闭塞后，对同侧进行听觉脑干反应（ABR）测量，以评估大鼠脑干血流与功能恢复之间的差异。波型分为三种类型：1型中，所有成分消失；2型中，所有成分短暂消失，然后重新出现；3型中，仅观察到I-IV成分之间的潜伏期差异显著增加。在2型中，我们认为所有成分重新出现是因为侧支循环迅速重建了耳蜗血流。
