Sodium balance, arterial pressure, and the role of the subfornical organ during chronic changes in dietary salt.

Randomized Controlled Trial

Animal

2005 Jul

Scientists removed a small brain area in rats and found that their blood pressure didn't change when they ate lots of salt or little salt — meaning that brain area isn't needed to keep blood pressure stable during salt changes.

When rats had a part of their brain (SFO) removed, they kept less salt in their bodies during the first few days of eating a very salty diet, meaning that part of the brain helps control how the body handles extra salt.
