Sensitive Periods, Vasotocin-Family Peptides, and the Evolution and Development of Social Behavior

Frontiers in Endocrinology, 2017
Nonapeptides, by modulating the activity of neural circuits in specific social contexts, provide an important mechanism underlying the evolution of diverse behavioral phenotypes across vertebrate taxa.

Sleep in the Cat: Raphe Dorsalis and Vasotocin [PDF]

Sleep, 1984
To determine the relationship between the raphe nuclei and the sleep-inducing pineal peptide arginine vasotocin (AVT), we investigated the hypnogenic effects of intraventricularly administered AVT in adult cats with electrolytic lesions performed either in the raphe dorsalis nucleus (RDN) or the raphe pontis nucleus (RPN).

The vasotocinergic system in the hypothalamus and limbic region of the budgerigar (Melopsittacus undulatus)

European Journal of Histochemistry, 2009
We report a morphological and biochemical analysis on the presence, distribution and quantification of vasotocin in the hypothalamus and limbic region of the budgerigar Melopsittacus undulatus, using immunohistochemistry on serial sections and ...

Arginine vasotocin regulation of interspecific cooperative behaviour in a cleaner fish. [PDF]

PLoS ONE, 2012
In an interspecific cooperative context, individuals must be prepared to tolerate close interactive proximity to other species but also need to be able to respond to relevant social stimuli in the most appropriate manner.

Vasotocin receptor blockade disrupts maternal care of offspring in a viviparous snake, Sistrurus miliarius

Biology Open, 2017
Parental care is a complex social behavior that is widespread among vertebrates. The neuroendocrine regulation of parent-offspring social behavior has been well-described in mammals, and to a lesser extent, in birds and fish.

High hydrostatic pressure effects on arginine vasotocin levels in fish

Aquatic Biology, 2020
The present study investigates the response of the hormone arginine vasotocin (AVT), the non-mammalian antidiuretic hormone, to the acclimation of fish to high hydrostatic pressure (5.1 MPa). Two fish species with different osmoregulatory strategies, the

The vasotocin-like biological activity present in the bovine pineal is due to a compound different from vasotocin [PDF]

Journal of Neural Transmission, 1981
The vasotocin-like biological activity detected in an extract (E5 fraction) of bovine pineal gland was found not to be due to the presence of vasotocin, vasopressin or oxytocin. The data obtained by means of bio- and radioimmunoassays suggest that the peptide responsible for this biological activity, however, possess the same Pro-Arg-Gly(NH2 ...

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Divergent neural nodes are species- and hormone-dependent in the brood parasitic brain. [PDF]

Genes Brain Behav
Mesotocin (MT, homologous to oxytocin in mammals) enhances natural preferences for egg‐related stimuli in brood‐parasitic and parental females alike. In the brain, MT treatment was associated with changes in gene expression in the bed nucleus of the stria terminalis and the preoptic area in brood parasitic females. Abstract Avian brood parasitism is an

EFFECT OF VASOTOCIN AND OXYTOCIN ON INTRAUTERINE PRESSURE IN THE HEN [PDF]

Reproduction, 1971
Summary. In anaesthetized hens, intravenous injections of vasotocin and oxytocin increased the intrauterine pressure. The response to vasotocin was much more intensive than to oxytocin.
