for vasopressin, a hormone linked to sexual motivation, bonding, and other social behaviors.
After comparing the brains of males with offspring with brains of childless males in mating pairs, Kozorovitskiy and Gould found that fathers not only had more connections between neurons in their prefrontal cortex, a region involved in anticipating consequences and attaining goals, but they also had more receptors
for vasopressin, a neurohormone linked to social interaction and bonding.
The two species» genes
for the vasopressin receptor — which relays the hormone's message to brain cells — have slightly different «promoters,» the switches that turn genes on and off.

for vasopressin neurons,» said Lowell.
By injecting the gene
for the vasopressin receptor into the ventral pallidum of promiscuous voles, researchers were able to make the cells in that area produce levels of the receptor comparable to those of monogamous species.
In the new work, Miranda M. Lim of Emory University and her colleagues inserted a gene that encodes
for the vasopressin receptor protein directly into the brains of male meadow voles.
Likewise in marmosets, receptors
for vasopressin in experienced dads were far more numerous compared to non-dads.

for those expressing the gene
for AVPR1a, a specific
vasopressin receptor.
Vasopressin is best known
for its role as a controller of the kidney; oxytocin helps the breast to expel milk and is involved in labour.

vasopressin group and 13 days in the norepinephrine group.
A team of researchers led by Dr. Elliott Albers, director of the Center
for Behavioral Neuroscience and Regents» Professor of Neuroscience at Georgia State University, and graduate student Joseph I. Terranova, has discovered that serotonin (5 - HT) and arginine -
vasopressin (AVP) act in opposite ways in males and females to influence aggression and dominance.
Andermann and colleagues, including co-corresponding author, Bradford B. Lowell, MD, PhD, a Professor of Medicine in the Division of Endocrinology, Diabetes and Metabolism at BIDMC, recorded the activity of neurons responsible
for releasing the anti-diuretic hormone
vasopressin in mice.
The dramatic proof came in an experiment in which the researchers were able to make a mouse more caring
for females by giving it the
vasopressin receptor gene from the prairie vole, well known
for being faithful and social.
Previous research had suggested that
vasopressin plays a role in social behavior, ranging from aggression and territorialism to pair bonding and caring
for young.
To see if differences in response to
vasopressin accounted
for the contrast in personality, the researchers took males from each species and paired them with females, which had been neutered to prevent them from leading on the males.
The origin of long - lasting relationships in many species seems to be a receptor
for the hormone
vasopressin, the so - called V1a receptor (V1aR).

vasopressin 1a receptor gene structure within and between vole species predicts behavior Elizabeth Hammock, Center
for Behavioral Neuroscience, Emory University, Atlanta, Georga, USA
ShareAnother hormone,
vasopressin, contributes to male nurturance of offspring — it makes
for caring fathers.
Among these systems, hypothalamo - neurohypophyseal magnocellular neurons have been early - considered models, as they typically display an electrical activity consisting of bursts of action potentials that is optimal
for the release of boluses of the neurohormones oxytocin and
vasopressin.
Oxytocin and
vasopressin in the human brain: social neuropeptides
for translational medicine
So it releases stuff like rennin, aldosterone, and another one called
vasopressin and your body even releases extra albumin in your blood and when this happens, your plasma volume expands and even though, while your exercising short term, especially
for like an aerobic session, your plasma volume decreases by 10 - 20 % by the time your body has bounced back and responded a single bout of intense exercise, especially like a long or hard session, can expand your plasma volume or your plasma fluid by 10 %.

For some, simply engaging in sex with your partner after a dry spell can get you back in the game; that is, it will get your rhythm going again, your energy aroused, and with more
