Abstract
The possible existence of plastic changes in the branching pattern and the complexity of silver-impregnated motor nerve terminals was studied in the extensor digitorum longus muscle of adult rats housed in metabolic cages or trained to walk. Results indicate a precise inverse relation between the amount of locomotor activity and the complexity finally attained by the motor nerve terminals.
摘要
在饲养于代谢笼中的成年大鼠或经训练行走的成年大鼠的趾长伸肌中，研究了银浸染运动神经终末分支模式和复杂性方面可能存在的可塑性变化。结果表明，运动活动量与运动神经终末最终达到的复杂性之间存在精确的反比关系。
