Do non-invasive maneuvers like lower-body negative pressure and head-up tilt modify carotid arterial diameter in normal subjects?
Mild lower-body negative pressure and head-up tilting significantly decrease carotid arterial diameter, suggesting local changes may influence carotid baroreceptors.
Lacolley et al. (1992) studied this question.
