Responses to rotation in many vertical and horizontal planes were studied in electrically identified secondary vestibular neurons of alert cats. This report concerns secondary neurons that gave responses which could not be explained as due to a summation of semicircular canal inputs. These cells responded to sinusoidal rotation of the cat in any vertical plane, and response phase depended on the plane of rotation. The responses were modeled as the result of summation of two inputs that differed in their spatial orientations and dynamics. Response dynamics and a comparison of responses to vertical and horizontal rotations showed that some cells were sensitive to rotation with respect to gravity. Their responses both to gravity and horizontal rotations argue that these secondary neurons received convergent otolith and canal inputs. Some cells also had oculomotor related discharges and/or responded weakly to neck rotation.
在警觉猫的经电识别的次级前庭神经元中，研究了其对多个垂直和水平平面旋转的反应。本报告涉及那些其反应无法解释为半规管输入总和所致的次级神经元。这些细胞对猫在任何垂直平面内的正弦旋转均有反应，且反应相位取决于旋转平面。这些反应被模拟为两个在空间方向和动力学上不同的输入总和的结果。反应动力学以及对垂直和水平旋转反应的比较表明，一些细胞对相对于重力的旋转敏感。它们对重力和水平旋转的反应表明，这些次级神经元接受了来自耳石和半规管的汇聚输入。一些细胞还具有与动眼相关的放电和/或对颈部旋转反应较弱。
