我们研究了不对称的紧张性颈反射对人类比目鱼肌运动神经元池的兴奋性的影响，通过映射H振幅作为旋转的函数的身体相对于固定的头部。对8名正常成年志愿者进行了测试。对于每名受试者，在每次改变体位之前和之后，针对以下每个测试位置（4°、8°、12°、16°）以及对照位置（0°），记录了右侧比目鱼肌的15次连续H反射。我们的研究结果表明，H反射的振幅进行性促进对侧旋转记录侧和相反抑制同侧旋转。结果表明，一侧颈感受器增强对侧比目鱼肌运动神经元的兴奋性，抑制同侧比目鱼肌运动神经元的兴奋性。
We studied the influence of the asymmetric tonic neck reflexes on the excitability of the human soleus motoneuronal pool by mapping the H amplitude as a function of rotation of the body relative to the fixed head. Eight normal adult volunteers were tested. On each subject 15 consecutive H reflexes were recorded from the right soleus muscle, for each of the following test positions, 4°, 8°, 12°, 16°, as well as at the control position (0°), both before and after each change in body position. Our results showed that the H reflex amplitude was progressively facilitated for contralateral rotation in respect to the recording side and conversely inhibited for ipsilateral rotation. The results indicate that neck receptors of one side enhance the excitability of the contralateral soleus motoneurons and depress the ipsilateral ones.
