Implication

Differential sympathetic firing estimates are hypothesis-generating; leaves open whether renal selectivity alters baroreflex-targeted interventions in humans.

Key Points

This research investigates how different levels of arterial baroreceptor activity affect discharge rates in vasoconstrictor fibres across various tissues.
Quantitative comparisons of reflexly induced vascular responses with regional vasoconstrictor fibre stimulations.
Assessment of discharge rates at varying baroreceptor activity levels in cats.
Skeletal muscle vasoconstrictor fibres showed discharge rates up to 8 imp/s, while renal fibres peaked at 4 imp/s when baroreceptors were unloaded.
Intestinal vasomotor fibres responded similarly to those in skeletal muscle under the same conditions.
Cutaneous arterio-venous anastomoses showed no activation upon baroreceptor unloading.
