Angiotensinergic and cholinergic receptors of the subfornical organ mediate sodium intake induced by GABAergic activation of the lateral parabrachial nucleus

Highlights • Facilitatory and inhibitory mechanisms involved in the control of sodium appetite. • Deactivation of the inhibitory mechanisms of the LPBN induces sodium intake. • SFO angiotensinergic and cholinergic mechanisms involved on sodium intake to muscimol in the LPBN. • SFO dissociated cells...

Zusammenfassung:	Highlights • Facilitatory and inhibitory mechanisms involved in the control of sodium appetite. • Deactivation of the inhibitory mechanisms of the LPBN induces sodium intake. • SFO angiotensinergic and cholinergic mechanisms involved on sodium intake to muscimol in the LPBN. • SFO dissociated cells are sensitive to angiotensinergic and cholinergic stimuli.
