[Effect of vasopressin and oxytocin on evoked activity of dorsal horn cells of an isolated segment of spinal cord in rat pups].
Effects of vasopressin and oxytocin on field potentials and action potentials of single cells in dorsal horn evoked by dorsal root stimulation were studied in isolated spinal cord segment of 2-3 weeks old rats. Both investigated neuropeptides depressed postsynaptic wave of the field potentials and evoked discharges of single cells. The participation of the hypothalamospinal neurohormonal system in modulation of sensory information in dorsal horn is discussed.
