为了探索动物耳药物中毒后脑于电位表现的一般规律及其作为客观听力指标的敏感性和可靠性,本文对豚鼠耳卡那霉素中毒后记录的脑干电位和耳蜗电位以及耳蜗组织学观察结果,应用统计学处理方法作了综合分析。脑干和耳蜗电位分别采用颅顶硬膜外埋植电极和耳蜗鼓阶内电极引导,声刺激均用短声。按我科“改良耳蜗
In order to explore the general rules of brain electrical potentiality in animal ear poisoning and its sensitivity and reliability as an objective hearing index, brain stem and cochlear potentials recorded after otakamycin poisoning in guinea pigs and histological observations of cochlea , The application of statistical methods for a comprehensive analysis. Brainstem and cochlear potentiostat were respectively implanted with skull top epidural electrodes and cochlear electrodes in the scala tympani. According to my department "to improve the cochlea
