↵F2-a Side of spinal cord ipsilateral to muscle nerve cut. Motor neurons in the medial gastrocnemius, lateral gastrocnemius, and soleus motor nuclei were evaluated in dorsolateral region of ventral horn (n = at least 3 animals).
↵F2-b Side of spinal cord ipsilateral to sciatic nerve cut. Motor neurons in the dorsolateral and ventrolateral motor pools were evaluated (n = at least 3 animals).
↵F2-c See also Chang et al. (1999).
↵F2-d Not significantly different between rat and cat; Fisher's exact test; p > 0.100.
↵F2-e Significantly different; Fisher's exact test;p < 0.05.
