Figure 6

Effect of bilateral orexin A (OX-A) injection in the RVLM on the arterial baroreflex evoked by i.v. injection of sodium nitroprusside (SNP) or phenylephrine hydrochloride (PE). (A) Representative experimental recording of the effect of changes in BP on sSNA due to SNP or phenylephrine before (control) or after orexin A injection. (B) Average sympathetic baroreflex function curves generated for data before (control) or after orexin A (50 pmol) injection (numbers of animals are shown in parentheses). Trace at right represents baroreflex gain for sSNA (error bars are omitted for clarity – see Table 1). The range and gain of the reflex are significantly increased.
