论文摘要
在运动过程中经常伸展神经。我们在这里研究伸展对孤子理论框架内神经兴奋性的影响。这种用于神经脉冲传播的热力学理论取决于神经膜中熔化的跃迁。在此转变中，神经膜的区域和神经厚度的变化。这取决于热力学变量，包括温度，麻醉药的化学电位和静水压力。与运动科学相关的进一步变化是神经的伸展，即是由肌肉收缩，关节的弯曲和肢体拉动的神经张力。我们在这里表明，孤子理论预测伸展时神经兴奋性的降低。这在减少复合作用电位的幅度和反射抑制的幅度时显而易见。我们将这些预测与医学发现进行比较。
Nerves are frequently stretched during movement. We investigate here the effect of stretch on nerve excitability within the framework of the soliton theory. This thermodynamic theory for nerve pulse propagation relies on the presence of a melting transition in the nerve membrane. In this transition, the area of the nerve membrane and the nerve thickness change. It depends on thermodynamic variables including temperature, the chemical potentials of anesthetics and on hydrostatic pressure. A further variable relevant for movement science is the the stretching of nerves, i.e., a tension in the nerve caused by muscle contraction, the bending of joints and the pulling on extremities. We show here that the soliton theory predicts a decrease in nerve excitability upon stretching. This becomes evident in a reduction of the amplitude of compound action potentials and in the suppression of reflexes. We compare these predictions with medical findings.
