Pregnancy attenuates central responses to atrial distension in rats; extends rodent models of volume sensing but leaves open human translation.
Does pregnancy modify the activation of central pathways following atrial distension in rats?
Pregnancy attenuates central neural responses to atrial distension, suggesting a mechanism for accommodating increased blood volume without triggering homeostatic reflexes.
Deng et al. (1995) studied this question.
