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

Exercise training alters the cardiopulmonary baroreflex regulation of the circulation; however, the mechanisms responsible are unknown. One possibility is an enhanced afferent response to cardiopulmonary stimulation. We therefore tested the…

Naloxone eliminates postexertional hypotension (PEH) in human and animal models. The effect of naloxone on sympathetic activity during hemorrhage and generation of arterial baroreflex function curves can be stimulated by blockade of cardiac afferent…

Diabetes, a syndrome characterized by high plasma glucose and low plasma insulin concentrations, is associated with somatic and autonomic neuropadiabetes as well as cardiac and vascular disorders. These consequences of diabetes significantly affect…

Recently, we were charged with providing a learning opportunity for high school students participating in the Upward Bound Regional Math and Science Program, a program designed to stimulate interest in mathematics and science for students from…

1. Local modulation of adrenergic responses was examined in the hindlimb vasculature of chronically instrumented intact conscious rats. Sprague-Dawley rats (n = 22) were instrumented with a Doppler flow probe around the right common iliac artery, a…

We hypothesized that lumbar sympathetic nerve activity (LSNA) increases at the onset of whole-body dynamic exercise in the rat. To test this hypothesis, we recorded LSNA, heart rate (HR), and arterial pressure (AP) at rest and during a graded…

Food restriction and/or starvation has a consistently greater and more permanent effect on physical growth in males than in females. Because diabetes may be viewed as being analogous to starvation, we tested the hypothesis that diabetes would reduce…
