Muscle potentials evoked by stimulation of the sciatic nerve were evaluated in 4- and 15-week-old chickens. Each bird was anesthetized and slowly cooled externally from a normal body temperature of 40 C to 28 C, and motor nerve conduction velocities were measured at various intervals during cooling. Motor nerve conduction velocity decreased linearly with decreasing limb temperature in both groups. The rate of change in motor nerve conduction velocity per degree in 2 groups (2.13 m/s/C vs 1.84 m/s/C) fell just short of a statistically significant difference (P = 0.0508), indicating that an age-related effect on temperature-associated variation in motor nerve conduction velocity may be present.
在4周龄和15周龄的鸡中评估了刺激坐骨神经诱发的肌肉电位。每只鸡均被麻醉，并从正常体温40℃开始在体外缓慢冷却至28℃，在冷却过程中的不同时间间隔测量运动神经传导速度。两组中运动神经传导速度均随肢体温度降低而呈线性下降。两组每摄氏度运动神经传导速度的变化率（2.13 m/s/℃对1.84 m/s/℃）略低于统计学显著性差异（P = 0.0508），表明可能存在年龄相关的对运动神经传导速度温度相关变化的影响。
