Synaptic effects from chemically activated fine muscle afferents upon α-motoneurones in decerebrate and spinal cats

In spinal and decerebrate cats fine muscle afferents (group III and IV) were selectively activated by intra-arterial injection of bradykinin and KCl into the gastrocnemius-soleus muscle. By this method the synaptic responses induced in lumbar α-motoneurones by fine muscle afferents could be examined...
