Central Sodium Sensing: Implications for Blood Pressure Regulation

Description

The ability of the brain to sense changing sodium levels in the blood is critical in mediating the neurohumoral responses to hypernatremia, however, the mechanisms underlying sodium sensing in humans is poorly understood. The purpose of this study is to identify key sodium-sensing regions of the human brain in older adults and determine if the Na-K-2Cl co-transporter mediates the neurohumoral response to acute hypernatremia. Completion of this project will increase our understanding of blood pressure regulation, which has major public health implications.
