Conference paper


The ongoing activity in the postganglionic sympathetic neurons innervating the cardiovascular effectors, the heart [2, 9, 10], and muscle resistance vessels [3, 6] is related to the cardiac and respiratory cycle. Since the temporal relationship between the cardiac cycle and sympathetic activity is abolished when all baroreceptor afferents have been cut, it is assumed that it is a consequence of the baroreceptor reflex [3]. The respiratory modulation in the sympathetic neurones may depend on the input from cardiopulmonary receptors [12], the blood pressure changes secondary to the mechanical movement of the thorax [6], and central coupling between respiratory and sympathetic neurons [1, 2, 5, 6].
