Efferents and afferents in an intact muscle nerve: background activity and effects of sural nerve stimulation in the cat

摘要

1. The background activity was observed in γ and α efferent fibres and in group I and II fibres innervating the muscle gastrocnemius lateralis or medialis. The reflex effects of ipsilateral and contralateral sural nerve stimulations on the muscle efferents were analysed together with their consequences upon the afferents of the same muscle. The observations were made in the decerebrated cat without opening the neural loops between the muscle and the spinal cord.
