[Ability of the opiate kappa-agonist bremazocine to facilitate the flexor reflex of the right hindlimb in spinal rats].

It has been found that bremazocine predominantly enhances the flexor reflex of the right hind limb, without affecting the left limb. The similarity of the visual data measuring the asymmetry of the pose and the asymmetry of EMG responses to painful stimulation has a high probability. No correlation between the asymmetry of the pose and EMG extensor activity has been found.
