Decerebrate cats with the spinal cord sectioned at low thoracic levels were submitted to rotations in the horizontal plane. The position of the animal with respect to the axis of rotation was such that horizontal canal afferents were activated either alone or in combination with macular afferents. The EMG activity from the triceps brachii muscles of both forelimbs was recorded. The main findings were as follows. (1) The motor output to each forelimb extensor is increased by an increase in the activity of the horizontal canal afferents from the contralateral labyrinth. The phase of the motor output with respect to that of the vestibular afferents shows a lag which increases with frequency, reaching about 85 degrees at 1.0 Hz. (2) The macular and horizontal canal inputs are independently processed in the central nervous system and the motor output in response to both inputs applied simultaneously is a linear summation of the outputs expected for each of the inputs.
将脊髓在胸段低位水平切断的去大脑猫置于水平面上进行旋转。动物相对于旋转轴的位置使得水平半规管传入神经单独或与黄斑传入神经一起被激活。记录了双侧前肢肱三头肌的肌电图活动。主要发现如下：(1) 来自对侧迷路的水平半规管传入神经活动增加会使每个前肢伸肌的运动输出增加。运动输出相对于前庭传入神经的相位显示出滞后，该滞后随频率增加，在1.0Hz时达到约85度。(2) 黄斑和水平半规管输入在中枢神经系统中独立处理，同时施加两种输入时的运动输出是每种输入预期输出的线性总和。
