Conduction velocities of nerve fibers proximal to muscle nerve transection in kittens and adult cats.
The nerves to the medial gastrocnemius muscle (MG) and to the soleus muscle (S) were transected unilaterally, close to the muscles, in young kittens and in adult cats. About 1 year postoperatively, conduction velocities of the fastest efferent and afferent fibers were assessed above the lesion in those cut nerves, which showed signs of an appropriate muscular reinnervation. The velocities were found to be subnormal in animals operated as kittens but normal in animals operated as adults.
