Changes of mean arterial pressure (Finapres; MAP), heart rate (HR) and sympathetic burst frequency (NBM) in reaction to barostat distension steps. Values are mean+-standard error. Maximal mean difference from baseline is shown in bold characters. Significance of changes was calculated on the delta values, not on the absolute values. For statistical results, see text and Fig. 3.
