The Brattleboro rat is a strain of laboratory rat descended from a litter born in West Brattleboro, Vermont in 1961 without the ability to produce the hormone vasopressin, which helps control kidney function. The rats' lack of vasopressin was the result of a naturally occurring genetic mutation. [citation needed]

The willingness of the female rats to access males was considered a direct measure of the females' levels of sexual motivation. An increase in vasopressin has been observed in female rats which have just given birth. Vasopressin is associated with aggressive and hostile behaviours, and is postulated to decrease sexual motivation in females.
In the U.S., the numbers of rats and mice used are not reported, but estimates range from around 11 million [3] to approximately 100 million. [4] In 2000, the Federal Research Division, Library of Congress, published the results of an analysis of its Rats/Mice/and Birds Database: Researchers, Breeders, Transporters, and Exhibitors.
Vasopressin is used to manage anti-diuretic hormone deficiency. Vasopressin is used to treat diabetes insipidus related to low levels of antidiuretic hormone. It is available as Pressyn. [53] Vasopressin has off-label uses and is used in the treatment of vasodilatory shock, gastrointestinal bleeding, ventricular tachycardia and ventricular ...
This video demonstrates a range in the severity of seizures which all fall into the five classical stages when a stimulus that causes seizures is added to the rat model. For example, rats can be seen rearing (standing on their hind legs) and falling over, which demonstrate the fourth and fifth Racine stages.
Vasopressin receptor 1A (V1AR), or arginine vasopressin receptor 1A (officially called AVPR1A) is one of the three major receptor types for vasopressin (AVPR1B and AVPR2 being the others), and is present throughout the brain, as well as in the periphery in the liver, kidney, and vasculature. [5] AVPR1A is also known as: V1a vasopressin receptor
The vasopressin receptor 2 blocker tolvaptan may also be used. [2] The presence of cerebral edema, or other moderate to severe symptoms, may necessitate intravenous hypertonic saline administration with close monitoring of the serum sodium levels to avoid overcorrection. [2]
