Cutting out a small part of the rat’s brain called the SFO didn’t change their blood pressure, even when they ate a lot more or a lot less salt than normal.

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 checked if their blood pressure changed when they ate lots of salt or little salt. It didn’t — their blood pressure stayed the same as rats with the brain area intact, so that brain area isn’t needed to control blood pressure 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.
