Abstract
We used time series analysis to characterize the relationships among the ar terial pulse (AP) and the cardiac-related and 10-Hz rhythms in sympathetic nerve discharge (SND) of urethane-anesthetized cats. We found that IO-Hz ac tivity was more tightly coupled to the AP than to the cardiac-related rhyth m. These data support the view that the dynamic coupling of AP and the 10-H z rhythm in SND involves a direct influence of baroreceptor activity on the 10-Hz oscillator. (C) 2000 Elsevier Science B.V.
