Bilateral MUSC into the DMH has no effect on the spontaneous or PGE2-evoked activity of tail CVC neurons. A–C: sequential segments of the activity recorded from a single tail CVC neuron. A: spontaneous discharge frequency (TC, 37.4°C) was unaffected by bilateral MUSC (arrowheads) into the DMH. B: increasing TC reduced the tail CVC neuronal discharge frequency to 1.6 Hz. MUSC into the DMH (arrowhead) had no effect on tail CVC neuronal discharge. C: 10 min after the second MUSC into the DMH (repeated portion of B), PGE2 into the POA increased the tail CVC neuronal discharge frequency. D: mean ± SE (n = 6 CVC neurons) discharge frequency of tail CVC neurons following bilateral MUSC into the DMH. White bars represent the mean control discharge frequency during the 1 min prior to MUSC into the DMH. Increasing TC (warming) reduced the tail CVC neuronal discharge frequency. *P < 0.05 compared with 10 min after MUSC in the DMH. **Significant (P < 0.05) increase in tail CVC neuronal discharge frequency compared with before PGE2 into the POA.
