CeA facilitatory and LPBN inhibitory mechanisms interact to control NaCl intake.
Naloxone in the CeA blocks NaCl intake by euhydrated rats with muscimol into the LPBN.
Naloxone in the CeA blocks NaCl intake by hyperosmotic rats with LPBN moxonidine.
Opioids in the CeA are important for sodium intake induced by LPBN deactivation.
Connection between LPBN and CeA mechanisms may depend on opioids action in the CeA.
