Abstract

A new method of eliciting auditory responses using bone-conducted stimuli was developed for use in freely-moving unanesthetized animals. In cats and rats piezoelectric materials were either bolted to or embedded within a dental acrylic skull platform. In order to produce acoustic stimulation, click and pip electrical waveforms were used to drive vibrations in the crystalline material. Responses to the crystal-elicited stimuli were compared with responses to air-coupled stimuli and were found to be virtually identical. Acoustic masking eliminated the response showing there is no significant contribution made to the responses by other sensory modalities.

摘要

一种利用骨传导刺激诱发听觉反应的新方法被开发出来，用于自由活动的未麻醉动物。在猫和大鼠中，压电材料要么用螺栓固定在牙科丙烯酸颅骨平台上，要么嵌入其中。为了产生声刺激，使用咔嗒声和短脉冲电波形来驱动晶体材料中的振动。将晶体诱发刺激的反应与空气耦合刺激的反应进行比较，发现它们几乎相同。声学掩蔽消除了反应，表明其他感觉模态对反应没有显著贡献。
