Water intake and activity of hypothalamoneurohypophysial system during osmotic and sodium stimulation in rats
TL;DR: The results do not completely rule out the participation of cerebrospinal fluid sodium receptors, but it is more likely that osmoreceptors regulate the activity of the hypothalamoneurohypophysial system and drinking behavior.

Cerebral metabolic and vasopressin and oxytocin responses during osmotic stimulation in conscious rats.

TL;DR: Intravenous infusion of hypertonic saline increased plasma [Na +] and osmolality and induced a short‐latency drinking response and plasma vasopressin and oxytocin concentrations increased, with a preferential increase of Oxytocin over vasoppressin.

Metabolism in the globus pallidus after fetal implants in rats with nigral lesions
TL;DR: The results indicate that the ability of an ipsilateral mesencephalic graft to ameliorate the motor behavior in rats with nigral lesions is associated with changes in the functional activity of the ipsilaterally globus pallidus.

Atriopeptin prevents angiotensin II-stimulated glucose utilization in the subfornical organ.
Eva Nermo-Lindquist,Massako Kadekaro,Mary Lee Terrell,James Nassar,Helena A. Lekan,Sondra Freeman +5 more
TL;DR: Findings indicate that atriopeptin III, an atrial natriuretic peptide, may act at the level of subfornical organ to antagonize the dipsogenic action of ANG II.
6
Effects of chemical stimulation of the subfornical organ on metabolic activity of the hypothalamo-neurohypophysial system in rats.
TL;DR: The results demonstrate the ANG II and ACh mobilize differentially the mechanisms increasing blood pressure, drinking responses, and the activity of the HNS.
