Abstract

Hearing thresholds were measured for 5 normal pigeons with the heart-rate conditioning method. After extirpation of the membranous cochlea on both sides and fenestration of the lateral canals, hearing thresholds were measured again with the same method at 250, 750 and 1500 Hz. Hearing thresholds found in this way for deaf fenestrated pigeons correspond very well to threshold values for the "Tullio effect". Electrical activity in the vestibular nerve evoked by sound is thought to be the origin of these phenomena.

摘要

采用心率条件反射法测量了5只正常鸽子的听阈。双侧膜迷路切除及半规管开窗术后，采用相同方法再次测量250、750和1500Hz频率下的听阈。以这种方式测得的失聪开窗鸽子的听阈与“图利奥效应”的阈值非常吻合。声音诱发的前庭神经电活动被认为是这些现象的起源。
