Abstract
- The relationship between conduction velocity and nerve diameter in single myelinated nerve fibres from Xenopus laevis was measured and was found to be linear.2. The relationship between conduction velocity and temperature in nerve fibres of various diameters was measured over the range 15-30 degrees C and was found to be linear for each fibre.3. The slope of the conduction velocity-temperature relationship was directly proportional to the diameter of the nerve fibre.4. The form of the conduction velocity-temperature relationship was determined by numerical solution of the Frankenhaeuser-Huxley equations for the case of a propagated action potential. The computation predicted that conduction velocity is a linear function of temperature over the range studied.
摘要
测量了非洲爪蟾单根有髓神经纤维的传导速度与神经直径之间的关系，发现二者呈线性关系。
在15至30摄氏度范围内测量了不同直径神经纤维的传导速度与温度之间的关系，发现每根纤维的该关系均为线性。
传导速度与温度关系的斜率与神经纤维直径成正比。
通过对传播动作电位情况下的弗兰克海泽-赫胥黎方程进行数值求解，确定了传导速度与温度关系的形式。计算预测在所研究的温度范围内，传导速度是温度的线性函数。
