The pattern of innervation of three muscles from rat (lateral gastrocnemius, biceps brachii, pectoralis minor) has been ascertained in the neonatal period (birth to 4 days) and from two to three weeks postnatal. Contraction, electrophysiological and histological methods were used to determine the pattern of innervation. There is a change in the segmental innervation during development which establishes the topographical projection of different segmental nerves found in mature muscles. Development of such topographical projections by different segmental nerves onto the muscles studied emerges as a consequence of elimination of terminals arising from the inappropriate segmental nerve.
已确定大鼠的三块肌肉（外侧腓肠肌、肱二头肌、胸小肌）在新生期（出生至4天）以及出生后两到三周的神经支配模式。采用收缩、电生理和组织学方法来确定神经支配模式。在发育过程中节段性神经支配存在变化，这种变化确立了成熟肌肉中不同节段神经的拓扑投影。不同节段神经在研究的肌肉上形成这种拓扑投影是由于消除了来自不适当节段神经的终末。
