From: Long-term blood pressure control: is there a set-point in the brain?
Analog recordings showing responses of arterial pressure (AP), mean arterial pressure (MAP), heart rate (HR), renal sympathetic nerve activity (RSNA), and mean RSNA to a ramp decrease in MAP by caval occlusion (Oc) after the intracerebroventricular (icv) infusion of artificial cerebrospinal fluid (aCSF), and then of s-methyl-l-thiocitrulline (SMTC, 50Â nmol), and l-arginine (l -Arg, 1,000Â nmol), modified from Ref. [76]. Each arrow indicates a peak response of mean RSNA to a ramp decrease in MAP by caval occlusion, modified from Ref. [76]
