Temporal parameters involved in retention of reflex alterations in spinal rats.
Temporal parameters concerning retention of a stimulation-induced hindlimb flexion were investigated. After spinal transection, 60 rats received 10, 20, 30, 40, 45, or 50 min of hindlimb stimulation. Consistent persistence of flexion following stimulus cessation was observed in rats that were stimulated for at least 30 min. When the results ae compared with previous data, the spinalized rat shows a 10-min reduction in the critical time interval needed to consistently obtain poststimulation persistence of flexion.
