While considerable information exists regarding the independent effects of caffeine and psychological stress on cardiovascular activity, there is relatively little information on their combined effects. Since caffeine may enhance cardiovascular responsivity to psychological stress, research on hemodynamic responses to caffeine-stress combinations may help elucidate mechanisms of hypertension development. In a series of studies, regular consumers of caffeine were exposed to laboratory and naturalistic stressors with and without prior caffeine intake. Among the findings were (1) caffeine and str

Despite the frequent use of antidepressants and the high incidence of obesity in Australia and many other developed countries, the relationship between major depressive disorder, obesity and antidepressant use remains complex.

Alcohol consumption on college campuses is a major public health concern, particularly among emerging adults. Extant literature has identified trauma exposure and posttraumatic stress as robust risk factors for problematic alcohol use. However, the mechanisms underlying this association are less well-studied. Research indicates that bodily arousal is a fundamental feature of trauma exposure and posits that internal stimuli (e.g., heart pounding) at the time of trauma may manifest into conditioned cues that can trigger posttraumatic responding and related symptomatology, including alcohol use.

<p> The social self preservation model posits that threats to the social self result in a unique and coordinated psychobiological response that evolved due to its adaptive benefits. Stressors that threaten the social self elicit feelings of shame and other negative self-conscious emotions, as well as increased hypothalamic-pituitary-adrenal (HPA) axis activity. The current study sought to test this model by exposing individuals to an acute stressor, and determining if they exhibit the emotional, physiological, and behavioral components proposed by the self preservation model. In addition, the

Stress in music performance shows an intrinsic relationship with changes in cardiovascular functioning and emotions, yet to date, studies analysing these stress indicators are few and far between. The overarching aim of this thesis is therefore to investigate performance stress through the lens of both self-reported anxiety and physical stress signatures in heart rate variability. For rigour, this is achieved through a close examination of the relationship between stress and structural complexity of heart rate variability in response to different conditions musicians underwent: (1) a low- and

Selenium (Se), an essential element, can bioaccumulate and become toxic. The main toxicity symptom in fish, teratogenicity, is mediated by oxidative stress; however, little is known about the effect of Se on the physiological stress response (PSR). The effects of Se on the PSR and oxidative stress parameters were investigated in rainbow trout, brook trout, and white suckers. The PSR was activated by acute and sub-chronic laboratory exposures to NaSeO3, but not exposure to environmental levels of Se. Species-specific sensitivity to Se may be explained by biochemical differences. Rainbow trout (

In these studies, we first compared the neuroendocrine responses between early (EL, PPD3-5), late (LL, PPD 15) lactating and virgin (V) females to a male intruder in the home cage. We next investigated whether the presence of the pups at the time of exposure to stress could modify the magnitude of the hormonal response to a male intruder in the home cage or to a predator odor (fox urine) in a novel environment. In the male intruder paradigm, levels of CRF mRNA expression in the PVN and CeA were lower in LL compared to EL or V females and plasma ACTH and B secretion was also reduced in L

Central administration of pmol and low nmol doses of neurotensin (NT), rapidly stimulated hypothalamic-pituitary adrenal (HPA) activity, increasing adrenocorticotropin hormone (ACTH) and corticosterone (B) release for several hours. This suggests potent effects of centrally administered NT and a role for this neuropeptide in HPA regulation. Of several brain areas thought to be involved in mediating NT-induced effects, one site of particular interest is the paraventricular nucleus of the hypothalamus (PVNh). Chronic implants of the NT antagonist, SR 48692 (powdered form), into the PVNh area dec
