Implicates mechanosensitive afferents over central command in sympathetic control during ischemia; hypothesis-generating for autonomic regulation in disease.
Does contralateral rhythmic handgrip modulate muscle sympathetic nerve activity during posthandgrip muscle ischemia in humans?
Mechanosensitive muscle afferents, rather than central command, appear to attenuate metaboreceptor-mediated increases in muscle sympathetic nerve activity during posthandgrip muscle ischemia.
Ray et al. (1994) studied this question.
