Effect of chronic sciatic nerve section on saphenous nerve input to midline bulboreticular formation in the rat.
The sciatic nerve was transected unilaterally 7-10 weeks before electrophysiological single unit recordings were made from somatically activated neurons in the midline bulboreticular formation of the rat. Their responses to high-intensity electrical stimulation of the saphenous nerve area were significantly stronger on the lesioned side. In control rats no such side difference was found. The result indicates that sciatic nerve transection unmasks polysynaptic somatic input to the midline bulboreticular formation.
