What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looked at how the brain detects changes in salt levels in the blood, which helps control blood pressure. Researchers used brain scans to find key areas involved in this process in 29 healthy adults aged 18-45. No treatment was given; the goal was simply to learn more about how blood pressure is regulated.
