Decerebrate cats with the spinal cord sectioned at low thoracic levels were subjected to sinusoidal rotations in the vertical plane, while recording the EMG activity of both triceps brachii muscles. The applied stimulus activated utricular and saccular receptors as well as the vertical semicircular canals. Using results presented in preceding papers 2,3, namely the dynamic response characteristics of the motor output to macular inputs and the fact that the responses to otolith and canal stimulation summate linearly 3, it is deduced that the dynamic characteristics of the motor output in response to stimulation of the vertical canals are the same as those to horizontal canal stimulation. The implication of these findings vis-à-vis the problem of central processing of vestibular inputs and the problem of postural stability is discussed.
将脊髓在胸段低位水平切断的去大脑猫在垂直平面上进行正弦旋转，同时记录肱三头肌的肌电图活动。施加的刺激激活了椭圆囊和球囊感受器以及垂直半规管。利用前两篇论文2,3中给出的结果，即运动输出对黄斑输入的动态响应特性以及对耳石和半规管刺激的响应呈线性叠加这一事实3，推断出垂直半规管刺激时运动输出的动态特性与水平半规管刺激时相同。讨论了这些发现对于前庭输入的中枢处理问题和姿势稳定性问题的意义。
