Fig. 5. Averaged effect of dorsal PAG modulation of baroreflex responses before and following lateral parabrachial nucleus (LPBN) microinjection.

Fig. 5

Open bars indicate baroreflex responses evoked by ADN stimulation alone. Hatched bars indicate baroreflex responses elicited during 40 Hz PAG stimulation before bilateral LPBN blockade. Black bars indicate ADN responses elicited during 40 Hz PAG stimulation after bilateral LPBN blockade. A. MAP and HR responses during 5 Hz ADN stimulation before and after LPBN microinjection (n=6/group). B. Baroreflex responses during 15 Hz ADN stimulation before and after LPBN microinjection (n=6/group). Baroreflex responses evoked alone reflect the average response elicited before and following LPBN microinjection. Left panels, muscimol at 0.45 nmol/side; middle panels, kynurenic acid 1.8 nmol/side; aCSF, 90 nl per side. * indicates significantly different (P<0.05) from ADN-alone evoked response. # indicates significantly different from response evoked by ADN + dorsal PAG stimulation before LPBN microinjection (P<0.05).
