The subfornical organ and the integration of multiple factors in thirst
Physiology & Behavior, 1984Rats with lesions centered on the ventral stalk of the subfornical organ (SFO) were used to characterize the participation of this structure in the control of drinking. It is concluded that the SFO does indeed play some minor role in the mediation of drinking following intraventricular injections of angiotensin. Further, it is shown that lesions of the

The subfornical organ in sodium appetite: Recent insights
Neuropharmacology, 2019To maintain sodium homeostasis, animals will readily seek and ingest salt when salt-depleted, even at concentrations that they typically find aversive when sodium replete. This innate behaviour is known as sodium (or salt) appetite. Salt appetite is subserved by a conserved brain network that senses sodium need and promotes the ingestion of salty ...

The Mammalian Subfornical Organ
1969Current investigations on the ultrastructure and function of the mammalian subfornical organ have been reviewed. Almost no information exists on the physiological significance of this structure. The results derived from anatomical research point towards a secretory function of its nerve cells.

The subfornical organ as a model of neurohumoral integration
Brain Research Bulletin, 1985Through its specialized morphology, sensitivity to angiotensin II, and strategic anatomical connections, the subfornical organ is intimately involved in the translation of peripheral thirst to behavioral and physiological actions for establishing body fluid homeostasis.

Electrophysiological identification of forebrain connections of the subfornical organ
Brain Research, 1986Experiments were performed in 17 urethane-anesthetized rats to investigate electrophysiologically neurons in the subfornical organ (SFO), which send efferent axons directly to the region of the paraventricular nucleus of the hypothalamus (PVH), the supraoptic nucleus (SON) and the nucleus medianus (NM).

Regional differences in the morphology of the rat subfornical organ
Brain Research, 1976Based upon scanning and transmission electron microscopy 3 regions are distinguished in the rat subfornical organ. The rostral region is dominated by nerve fibers interspersed with relatively few neurons and glial cells. Squamous to low cuboidal ependymal cells with flat ventricular surfaces bearing a few short microvilli line the center of this region;

The subfornical organ: a novel site of action of cholecystokinin
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2014The subfornical organ (SFO) is an important sensory circumventricular organ implicated in the regulation of fluid homeostasis and energy balance. We investigated whether the SFO is activated by the hormone cholecystokinin (CCK). CCK1and CCK2receptors were identified in the SFO by RT-PCR.

Topographical Distribution of Acetylcholinesterase in the Subfornical Organ of the Rat
Cells Tissues Organs, 1984Acetylcholinesterase (AChE) activity in the rat subfornical organ (SFO) was determined by the Koelle and Friedenwald method. Coronal sections showed a homogeneous reaction in the rostral region, which adopted a ring-like form in the anteromedial zone and a horseshoe pattern in the posteromedial zone.

The role of the subfornical organ in the drinking behavior of the pigeon
Brain Research, 1986Pigeons with radiofrequency lesions that damaged the subfornical organ (SFO) (n = 4) or that isolated it from adjacent structures (n = 5), but not sham-lesioned pigeons, were unresponsive to blood-borne (i.p.) ANG II (100 micrograms/pigeon) in the immediate postoperative period and for 60 days thereafter.

Ultrastructure of the subfornical organ of the chicken (Gallus domesticus)
Cell and Tissue Research, 1979The SFO of the chicken is divided in half by a large central blood sinus; ventrally it is covered by a thin layer of ependyma (including tanycytes, dendrites, and axons) which connects the two lateral halves and protrudes as a midsagittal crest into the lumen of the third ventricle.
