[Monosynaptic reflex responses of the spinal cord after the removal of the bones of the shin and thigh in white rats].
To analyse the mechanisms of the increase of excitability of the spinal cord neurons after division of a nerve, the author studied the character of changes of the monosynaptic responses (MSR) of the ventral spinal cord root in albino rats 5 days and 4 weeks after removal of the bones of one hind limb. The MSR did not change in 5 days but intensified significantly in 4 weeks as compared to the monosynaptic responses on the contralateral side. The possible mechanisms of the increase of MSR after osteotomy and division of a nerve are discussed.
