Small and short-lasting physiologic variations in the locomotor activity of normal adult rats can induce remodelling in the motor nerve endings of the fast extensor digitorum longus muscle. The specificity and relative importance of the different plastic adaptations occurring in the presynaptic axonal tree have been studied, in silver impregnated nerve endings, by using an automatic image analysis treatment of the nerve terminals' geometric properties and a discriminant analysis of the morphometric parameters. Changes observed, like selective length variations in certain terminal segments and positional rearrangements, agree with a mechanism of neural connectivity regulation in the adult that arises as a consequence of normal neuromuscular activity.
正常成年大鼠运动活动中微小且短暂的生理变化可诱导快速趾长伸肌运动神经末梢发生重塑。通过对神经末梢几何特性进行自动图像分析处理以及对形态测量参数进行判别分析，在银浸染的神经末梢中研究了突触前轴突树中发生的不同可塑性适应的特异性和相对重要性。观察到的变化，如某些终末节段的选择性长度变化和位置重排，与正常神经肌肉活动导致的成体神经连接调节机制相符。
