方法记录来自左侧上级前庭神经的传入活动。通过植入圆窗和中耳底部的电极输送阴极（兴奋性）和阳极（抑制性）电流（50-250 µA）刺激右耳。尽管100 µA电流接近传出介导交叉效应的阈值，但选择该电流幅度作为标准刺激，因为较高的电流可能导致反射性运动和/或直接扩散到对面（左侧）迷路。
METHODSAfferent activity was recorded from the left superior vestibular nerve in precollicularly decerebrated chinchillas. The right ear was stimulated by cathodal (excitatory) and anodal (inhibitory) currents (50–250 µA) delivered through electrodes implanted on the round window and in the floor of the middle ear. Even though 100-µA currents were near the threshold for efferent-mediated crossed effects, this current magnitude was chosen as a standard stimulus because higher currents could result in reflexive movements and/or direct spread to the opposite (left) labyrinth.
