Spinal inhibition of descending command to soleus motoneurons is removed prior to dorsiflexion

摘要: Non-technical summary: The coordination of antagonistic muscle activity starts well in advance the onset voluntary movement. We recently demonstrated that antagonist responses evoked by stimulation brain were increased prior to contraction at ankle. Although our data indicated this was explained activation a subcortical motor program, neural pathways involved are unknown. Here we probe transmission underlying neuronal networks peripheral nerve order investigate responsible for facilitation responses. demonstrate produces spinal inhibition responses, which is removed contraction. propose removal might explain This mechanism enable direction movement be changed quickly during functional tasks such as dribbling.
