Functional change in the rat spinal cord by chronic spinal transection and possible roles of monoamine neurons.


Two types of spinal reflex responses, extensor reflex and ventral root potential, were compared physiologically and pharmacologically in acute and chronic spinal cord transected rats. The recovery curve of the extensor reflex, recorded as evoked electromyogram, in chronic spinal rats was strikingly different from that in acute spinal rats. Namely… (More)
