在本技术报告中，我们描述了一种用于单半规管的机械刺激方法，该方法具有可重复性，灵敏性和离散性。机械刺激器能够在宽频率范围内传递不同波形的可靠受控刺激，其产生内淋巴运动和随后的杯偏转，而不向动物施加运动。本文报道了宽频带机械刺激鸽子（Columba livia）水平半规管传入纤维的电生理实验结果。传入纤维引起的自然偏航旋转和机械刺激的反应进行了比较，结果表明，这两种刺激方法产生的反应，从同一传入单位，可以等同的幅度。此外，结果描述了从几个控制实验进行，以确定机械刺激技术的功效。
In the present technical report, we describe a method of mechanical stimulation for single semicircular canals that is reproducible, sensitive, and discrete. The mechanical stimulator is capable of delivering reliable controlled stimuli of different waveforms over a wide frequency range that produce endolymph movements and consequent cupula deflections without motion being imparted to the animal. The results of electrophysiological experiments where the responses from pigeon (Columba livia) single horizontal semicircular canal afferent fibers produced by mechanical stimulation across a broad frequency bandwidth are reported. Comparisons between afferent fiber responses elicited by natural yaw rotation and mechanical stimulation were conducted, with the results indicating that the two stimulation methods produced responses from the same afferent unit that could be equated in magnitude. In addition, results are described from several control experiments that were conducted in order to determine the efficacy of the mechanical stimulation technique.
