    ..However, when patients with dual renal arteries received renal nerve ablation in all arteries there was trend towards a greater BP reduction. Insufficient renal sympathetic nerve ablation may account for these differences. ..

    ..We also demonstrate the NK1 receptor on bulbospinal neurons of the ventral respiratory group, in a region overlapping the pre-Bötzinger Complex. ..
  3. James C, Macefield V, Henderson L. Real-time imaging of cortical and subcortical control of muscle sympathetic nerve activity in awake human subjects. Neuroimage. 2013;70:59-65 pubmed publisher
    ..This suggests that activity within suprabulbar regions may regulate resting MSNA by projections to the premotor sympathetic neurons in the rostroventrolateral medulla. ..
  4. Powis D. Alpha 2-adrenoceptor blockade prevents cardiac glycoside-evoked neurotransmitter release from sympathetic nerves in dog saphenous vein. Br J Pharmacol. 1987;92:213-20 pubmed
    ..7. It is concluded that the cardiac glycoside-evoked increase in neurotransmitter release from noradrenergic nerve terminals ofdog saphenous vein is modulated by a mechanism that involves an alpha2- adrenoceptor. ..
  5. Kashihara K, Kawada T, Sugimachi M, Sunagawa K. Wavelet-based system identification of short-term dynamic characteristics of arterial baroreflex. Ann Biomed Eng. 2009;37:112-28 pubmed publisher
    ..In conclusion, the dynamic baroreflex property to various pressure inputs could be simultaneously extracted from the step responses with background noise. ..
  6. Xing T, Pilowsky P. Acute intermittent hypoxia in rat in vivo elicits a robust increase in tonic sympathetic nerve activity that is independent of respiratory drive. J Physiol. 2010;588:3075-88 pubmed publisher
    ..Sympathetic LTF is not linked to the change in baroreflex function, since the baroreflex appears to be enhanced rather than impaired, but does play an important role in the enhancement of the hypoxic chemoreflex. ..
  7. Iigaya K, Müller Ribeiro F, Horiuchi J, McDowall L, Nalivaiko E, Fontes M, et al. Synchronized activation of sympathetic vasomotor, cardiac, and respiratory outputs by neurons in the midbrain colliculi. Am J Physiol Regul Integr Comp Physiol. 2012;303:R599-610 pubmed publisher
    ..We propose that the synchronized sympathetic-respiratory responses are driven by a common population of neurons, which may normally be activated by an acute threatening stimulus. ..

  9. Macefield V, Gandevia S, Henderson L. Neural sites involved in the sustained increase in muscle sympathetic nerve activity induced by inspiratory capacity apnea: a fMRI study. J Appl Physiol (1985). 2006;100:266-73 pubmed
    ..Given that many of these sites have roles in cardiovascular control, the sustained increase in MSNA during an inspiratory capacity apnea is likely to originate from a distributed set of discrete areas. ..
