The otoliths are stimulated in a particular pattern by any head movement that is not about an earth-vertical axis and evoke compensatory eye movements in the cat. Such eye movements are not produced if the otolith stimulation is accompanied by vertical canal stimulation. Vertical canal stimulation inactivates the velocity store (a central neural representation of head velocity) as seen by the attenuation of optokinetic after-nystagmus. These observations provide further evidence for the involvement of the central velocity store in the generation of otolith-evoked nystagmus.
任何非绕地球垂直轴的头部运动都会以特定模式刺激耳石,并在猫身上引发代偿性眼动。如果耳石刺激伴有垂直半规管刺激,则不会产生这种眼动。如视动性眼震后眼震减弱所示,垂直半规管刺激会使速度存储(头部速度的中枢神经表征)失活。这些观察结果为中枢速度存储参与耳石诱发眼震的产生提供了进一步证据。
