Nitric oxide is a quite salient signaling molecule, instrumental in both learning and memory. The chemical compound nitric oxide is a gas with chemical formula NO. It is an important signaling molecule in the body of mammals including humans, one of the few gaseous signaling molecules known. ...

Research has shown, quite extensively, that NO or nitric oxide is involved in the formation of learning in rodents. Neurobiologists, internationally, are enthralled with the potential benefits of this molecule.

As well, Nitric oxide, also once known as EDRF, may have a possible role in the type of memory which subserves object recognition.

This molecule is derived from the vascular endothelium, and since its is a gaseous molecule, it diffuses across the membrane and impacts the tonicity of the perivascular smooth muscle. It helps the muscle around the blood vessel, to relax. This is why this paradigm is involved in the action of sildenafil citrate (Viagra) Vascular is an adjective for the word vessel and refers to tube-like structures. ... The endothelium is the layer of thin, flat cells that lines the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. ... It has been suggested that Net flux be merged into this article or section. ... The elastic tension of living muscles, arteries, etc. ... Sildenafil citrate, sold under the name Viagra, is a drug used to treat male erectile dysfunction (impotence), developed by the pharmaceutical company Pfizer. ...

Studies were done in the Netherlands, by researchers and results should be of interest to those individuals concerned with aging, and the biology of longevity, and staying health.
