Activity was recorded from physiologically identified baroreceptor or chemoreceptor fibers in carotid sinus nerves of urethane-anesthetized spontaneously breathing rabbits. A carotid sinus area was vascularly isolated so that carotid sinus pressure…
The influence of daily spontaneous running (DSR) on the sympathetic (SC) and parasympathetic components of the arterial baroreflex control of heart rate (HR) was examined in 16 female Long Evans rats [8 sedentary (SED) and 8 DSR]. After
This study was designed to test the hypothesis that the increase in sympathetic nerve activity (SNA) and mean arterial pressure (MAP) at the onset of exercise is dependent on a rapid upward shift of the operating point of the arterial baroreflex. To…
