Should not yet change clinical practice for autonomic modulation; leaves open baroreceptor primacy in disease states.
Does varying respiratory motor output affect within-breath modulation of muscle sympathetic nerve activity in healthy humans?
Respiratory modulation of muscle sympathetic nerve activity in humans is primarily determined by feedback from baroreceptors and pulmonary stretch receptors rather than respiratory motor output.
Croix et al. (1999) studied this question.
