Several neurological control strategies for fast head movements are considered using computer simulations of a stretch reflex model. Each control strategy incorporates a different amount of proprioceptive feedback contributing to braking and/or clamping the movement. The model behavior for each control strategy is qualitatively compared to experimental data that includes the agonist and antagonist EMGs, and the head position, velocity, and acceleration. Significance of the study is discussed with respect to the characteristic tri-phasic EMG pattern for fast voluntary movements and the possible roles that the stretch reflex may have in contributing to this pattern of activation.
利用伸展反射模型的计算机模拟，对几种快速头部运动的神经控制策略进行了研究。每种控制策略都包含不同量的本体感受反馈，这些反馈有助于制动和/或限制运动。将每种控制策略的模型行为与实验数据进行定性比较，实验数据包括主动肌和拮抗肌的肌电图，以及头部位置、速度和加速度。针对快速自主运动的典型三相肌电图模式以及伸展反射在促成这种激活模式中可能发挥的作用，讨论了该研究的意义。
