Effects of intrathecal administration of VIP on reflex bladder contractions recorded under isovolumetric conditions in chloralose-anesthetized cats. A, B In a cat with an intact spinal cord, large doses of VIP (1 and 10 µg) inhibited bladder activity. C In a chronic spinal cord transected cat, a small dose of VIP (0.1 µg) facilitated bladder activity
