A preparation is described that permits the monitoring of activity from individual muscle afferent nerve fibres in an intact peripheral nerve in the forelimb of the cat. The nerve is a fine branch of the deep radial that supplies the indicis proprius muscle. When it is freed from nearby tissue over a length of 2-5 cm and placed in continuity over a silver hook electrode, it becomes possible to identify and monitor the impulse activity from each muscle afferent fibre activated by stretch or vibration applied to the muscle tendon or by focal mechanical stimulation of the muscle at the presumed site of individual spindle receptors. With this preparation it is possible to examine the central actions and security of transmission at central synaptic targets for single, identified muscle afferent fibres arising in the cat's forearm.
本文描述了一种制备方法，该方法可用于监测猫前肢完整外周神经中单个肌肉传入神经纤维的活动。该神经是桡神经深支的一个细分支，支配示指固有肌。当将其在2-5厘米的长度范围内从附近组织中游离出来，并连接在银钩电极上时，就能够识别和监测由施加于肌腱的拉伸或振动，或通过在单个梭形感受器假定部位对肌肉进行局部机械刺激所激活的每根肌肉传入纤维的冲动活动。通过这种制备方法，可以研究猫前臂中单个已识别肌肉传入纤维在中枢突触靶点的中枢作用和传递安全性。
