Vestibular responses (vertigo, nystagmus-like eye movements) to acoustic stimuli are known as the "Tullio phenomenon". Detailed electro-oculographic analysis of this reaction, as observed in a 30-year-old patient, revealed the following: a maximum amplitude of eye movement (mainly vertical) was achieved by sine wave bursts of high intensity, a frequency of 500 to 1000 Hz and a duration of 100 ms. The ocular deviation was composed of a fast initial component, followed by a slower resetting movement that was often divided into two parts of different velocities. At longer stimulus durations (more than 100 ms) the electro-oculogram showed a fractionation of the eye deviation, terminating in an "off-response". Various positions of the patient's head influenced the direction of the eye motion. The possibility that the Tullio phenomenon may be due to an abnormal excitation of the statolith organs is discussed.
对声音刺激的前庭反应（眩晕、类似眼球震颤的眼动）被称为“图利奥现象”。在一名30岁患者身上观察到的这种反应的详细眼电图分析显示如下：高强度、频率为500至1000赫兹、持续时间为100毫秒的正弦波脉冲可使眼球运动（主要是垂直方向）达到最大幅度。眼球偏差由快速的初始成分组成，随后是较慢的复位运动，该运动通常分为两个不同速度的部分。在较长的刺激持续时间（超过100毫秒）时，眼电图显示眼球偏差出现分节现象，最终以“关闭反应”结束。患者头部的不同位置会影响眼球运动的方向。文中讨论了图利奥现象可能是由于耳石器官异常兴奋所致的可能性。
