2) The majority of the animals gradually recovered from the limping state and after 3 or 6 months they were able to walk almost normally.
3) Then the sites of nerve sutures were exposed and proximal part of each nerve was stimulated faradically. In most cases the response proved to be paradoxical; for instance, the stimulation of N. fibularis gave rise to plantar flexion of the foot, thus suggesting the successful healing of the crossed nerve suture. Curiously enough, there were some cases, in which the stimulation of both nerves brought about the same effect, for instance the dorsiflexion of the foot. There were also some others, in which a quite usual response resulted from the stimulation, although the gross and microscopic examinations did not show the failure of the crossed suture.
4) In all cases the microscopic preparations revealed regenerated nerve fibers extending distalwards through the crossed suture. The less the nerve scar is formed, the better seems to be the functional recovery.
5) In view of the fact that antagonistic peripheral nerves can be crosswise anastomosed without leaving much functional deficiency, it may be quite reasonable to assume that the function of the central nervous system can be changed adapting to the new situation in the periphery. (author's abstract)
