sympathetic nerve
On day 15, mean arterial pressure, heart       rate, central venous pressure, and renal sympathetic nerve activity were recorded       in conscious rats at rest and in response to air-jet stress,       intracerebroventricular injection of the alpha(2)-agonist guanabenz (25 and 75       micrograms) or angiotensin II (30 ng), acute volume expansion, and ramp changes       of blood pressure by +/-50 mm Hg with phenylephrine and nitroprusside.
