Rodent studies have identified specialized sodium chloride (NaCl)-sensing neurons in the circumventricular organs (CVOs), which mediate NaCl-induced changes in sympathetic nerve activity, arginine vasopressin (AVP), thirst, and blood pressure (BP). In humans, acute hypernatremia has been shown to increase sympathetic nerve activity, AVP, thirst and BP. However, few human studies have investigated the network of NaCl sensing regions of the brain using functional magnetic resonance imaging (fMRI). OBJECTIVE: To determine how the functional connectivity of sodium sensing regions of the brain change during an acute hypernatremic perturbation...
