Forebrain Electroneutral Transporters in Salt-sensitive Hypertension: an MRI Study

This MRI brain study is looking at how specific proteins in the brain that regulate salt and fluid balance may contribute to high blood pressure that is sensitive to salt intake. Healthy volunteers are needed to help establish baseline comparisons for people with salt-sensitive hypertension. **You may be eligible if...** - You are between 40 and 60 years old - Your blood pressure is in the normal-to-mildly elevated range (100/60 to 140/90 mmHg) - Your BMI is between 18.5 and 30 - Your potassium level and general health are normal - You have no history of heart, kidney, metabolic, or neurological disease **You may NOT be eligible if...** - You are outside the 40–60 age range - You have high or low blood pressure, abnormal BMI, or abnormal potassium - You have a history of cancer, cardiovascular, respiratory, psychiatric, or neurological disease - You are currently using tobacco, nicotine, or hormone replacement therapy - You are pregnant or nursing - You have a diagnosed anxiety, depression, or other psychiatric condition Talk to your doctor to see if this trial is right for you.
