Abstract

Endocochlear potential (EP) responses to anoxia in immature and mature guinea pigs were compared. The EP decreased much more slowly after anoxia in guinea-pig embryos than in neonates. In many of the embryos, the EP failed to reach any negative voltage. These findings show that the development of the negative component of the EP is a function of the maturation of its positive component.

摘要

比较了未成熟和成熟豚鼠内耳蜗电位（EP）对缺氧的反应。豚鼠胚胎缺氧后EP下降的速度比新生豚鼠慢得多。在许多胚胎中，EP未能达到任何负电压。这些发现表明，EP负成分的发育是其正成分成熟的函数。
