我们研究了，在去大脑猫，外周输入同侧后肢L4神经元的活动调制颈部旋转（“颈部调制神经元”）。大多数神经元接受来自肌神经、皮神经和混合神经的会聚输入。在大约一半的神经元肌肉输入包括短潜伏期组I或组II的兴奋或抑制，与组II的影响更频繁。这种突触活动几乎完全是由刺激四头肌或缝匠肌产生的。在其他神经元肌肉传入只产生晚期，弥漫性兴奋或抑制，阈值通常在III组范围内。
We studied, in decerebrate cats, peripheral input from the ipsilateral hindlimb to L4 neurons whose activity was modulated by neck rotation (‘neck-modulated neurons’). Most neurons received convergent input from muscle, cutaneous and mixed nerves. In about half the neurons muscle input consisted of short-latency group I or group II excitation or inhibition, with group II effects far more frequent. Such synaptic actions were produced almost entirely by stimulation of quadriceps or sartorius. In the other neurons muscle afferents produced only late, diffuse excitation or inhibition, with thresholds usually in the group III range.
