On oxytocin and social behavior
… cognitive processes underlie social behavior. Oxytocin has long been recognized as crucial in social behavior in animals, but its role in regulating human social cognition and behavior is less clear, particularly with regard to endogenous oxytocin. The aims of this thesis were to investigate …

Effects of Oxytocin On Human Aggression
<p>EFFECTS OF OXYTOCIN ON HUMAN AGGRESSION</p> <h1>Joseph Louis Alcorn III, B.S.<strong></strong></h1> <p>Advisory Professor: Scott D. Lane, Ph.D.</p> <p>Human interaction is comprised of common, yet complex, behaviors and the outcomes of these social behaviors can beneficially or detrimentally …

PARTIAL SPINAL NERVE LIGATION ALTERS ANATOMICAL COMPONENTS OF OXYTOCIN SIGNALING AND THE LEVEL OF TONIC OXYTOCIN-MEDIATED INHIBITION OF NOCICEPTION
… in activity of endogenous pain inhibition. Oxytocin is a peptide that has been characterized for its analgesic properties and recent studies suggest that oxytocin may contribute to endogenous inhibitory tone in chronic pain. We investigated mechanisms of oxytocin signaling that may be …

Investigation of the oxytocin receptor gene in sheep
The increase in uterine oxytocin receptor (OTR)concentrations over the late luteal phase of the estrous cycle in sheep is thought to play an important role in the regulation of the cycle length by facilitating the effect of oxytocin on uterine prostaglandin release. At the end of pregnancy, a …

Oxytocin and Genetic Links with Eating Behaviours and Relevant Endophenotypes
Oxytocin (OXT) is an ancestral neuropeptide hormone essential in the regulation of human behaviours vital for sustaining life such as food intake and reproduction. Importantly, these behaviours have strong associations with the brains reward circuitry. To date, there has been little OXT-genetic …

Identification of central circuitry components mediating anorexigenic properties of oxytocin
… discoveries showing that a neurohormone, oxytocin (OT), acts as an appetite suppressant. Importantly, OT decreases energy needs-driven consumption of high-calorie foods by promoting early satiation, and it terminates intake motivated by palatability related to sweet taste. OT’s …

ROLE OF OXYTOCIN AND OXYTOCINASE IN THE MATERNAL RECOGNITION OF PREGNANCY
… with an emphasis on understanding the role of oxytocin and oxytocinase in early pregnancy. The first objective was to validate the safety and health outcomes of mares following a transvaginal ultrasound-guided ovarian (TVOB) and serial luteal biopsy (TVLB), which was utilized as a means to …

Oxytocin, Dopamine, and the Neuromodulation of Mating Behavior in C. Elegans
… I look at both the "how" and the "why" of oxytocin as a releaser of reproductive behavior. To do so, I take the wide view across 600 million years of metazoan evolution, focusing on the oxytocin-mediated mating behavior and physiology of the often-overlooked invertebrates. By looking to …

The Role of Oxytocin in Bovine Satellite Cell Proliferation and Differentiation
Steroid hormones are reported to increase oxytocin (OXT) expression in skeletal muscle. It is possible that OXT may play essential roles in satellite cell (SC) proliferation and differentiation, which further contribute to skeletal muscle development and growth. In this dissertation, we tested this …

Einfluß von endogenem Oxytocin auf die neuroendokrine und verhaltensbiologische Streßreaktivität unterschiedlicher Tiermodelle
Diese Arbeit konnte eine inhibitorische Kontrolle der HPA-Achse unter basalen und Streß-induzierten Bedingungen durch intrazerebrales OXT zeigen, die zumindest anteilig über Neuronen des hypothalamischen PVN vermittelt wird. Die neurohypophysäre Freisetzung von OXT und das angstbezogene Verhalten …

The Effect of Intranasal Oxytocin on Neural Functioning in Widow(er)s
… neuropharmacological manipulation via intranasal oxytocin (INT OT) administration. Method: A mixed sample of 37 spousally-bereaved older adults (CG =17; ncomplicated grief (NCG) = 20), completed the AAT, with 3 stimulus categories (spouse, stranger, and generic grief) during fMRI acquisition under …

Impact of prophylactic intranasal oxytocin administration on symptoms of post-traumatic stress
… severe emotional trauma. Research suggests that oxytocin treatment decreases PTSD symptoms. This study served to evaluate the efficacy of intranasal oxytocin pre-treatment on symptoms related to PTSD. The hypotheses are that oxytocin will decrease fear and anxiety, and increase reward-seeking …

Impact of Oxytocin and Tetrahydrocannabinol on signs of fear in the rat
<p>BACKGROUND: Oxytocin (OXT) has been used as a post-treatment for post-traumatic stress disorder (PTSD). Previous research suggests that pre-treatment of intranasal OXT attenuates signs of fear in rats; however, the impact of intraperitoneal (i.p) OXT pre-treatment on signs of fear in rats is …

Oxytocin and Social Sensitivity: Implications for Vulnerability to Stress and Depressive Symptoms
Oxytocin is a neuropeptide that has been implicated in several prosocial behaviors, such as trust, empathy and social affiliation, and might contribute to mental health disorders marked by social disturbances. Indeed, Chapter 1 indicated that the accumulated evidence points to interactions between …
