title: Coupling of arterial pulse and 10-Hz rhythm in sympathetic nerve discharge.
abstract: We used time series analysis to characterize the relationships among the arterial pulse (AP) and the cardiac-related and 10-Hz rhythms in sympathetic nerve discharge (SND) of urethane-anesthetized cats. We found that 10-Hz activity was more tightly coupled to the AP than to the cardiac-related rhythm. These data support the view that the dynamic coupling of AP and the 10-Hz rhythm in SND involves a direct influence of baroreceptor activity on the 10-Hz oscillator.
