The Contribution Of Nmda Receptors Within The Central Nucleus Of The Amygdala To The Suppression Of Pain Affect, Catherine Ann Spuz
The Contribution Of Nmda Receptors Within The Central Nucleus Of The Amygdala To The Suppression Of Pain Affect, Catherine Ann Spuz
Wayne State University Dissertations
The amygdala processes stimuli that threaten an individual and organizes the execution of affective behaviors designed to cope with the threat. The prototypical threat to an individual is exposure to a noxious stimulus. The central nucleus of the amygdala (CeA) receives nociceptive afferents and exhibits neuronal activation in response to noxious peripheral stimulation. NMDA receptors within CeA mediate this noxious-evoked neural excitation, and previous studies in the laboratory have shown that blockade of CeA NMDA receptors via the antagonist APV elevates the threshold for noxious tail-shock-induced vocalization afterdischarges (VADs), a validated measure of pain affect in the rat. The present …
Predicting Adolescent Risk-Taking And Goal-Oriented Behaviors: An Ecological Perspective, Joshua Jon Tynan
Predicting Adolescent Risk-Taking And Goal-Oriented Behaviors: An Ecological Perspective, Joshua Jon Tynan
Wayne State University Dissertations
An important aspect of human development is adolescence. It has been well documented that adolescence is a time during which individuals partake in the greatest amount of risk-taking behaviors. These behaviors often include having unsafe sex, drug and alcohol use, smoking and recklessness. On the other hand, goal oriented behaviors are also developing, although these have been less well studied. The current study explored several key contexts that adolescents are concurrently exposed to, including parenting behaviors, peer relationships, religion, and media. The outcomes of interest were risk-taking behaviors and goal-oriented behaviors. Ultimately the purpose of this study was to compile, …
Spirituality And Spiritual Self-Care: Expanding Self-Care Deficit Nursing Theory, Mary Louise White
Spirituality And Spiritual Self-Care: Expanding Self-Care Deficit Nursing Theory, Mary Louise White
Wayne State University Dissertations
The purpose of this study was to extend the theory of self-care deficit nursing by including specific constructs of religion, spirituality, and spiritual self-care practices within the structure suggested by Orem's self-care deficit nursing theory. Based on an extensive literature review, practice experience, and a discovery theory-building approach, a new mid-range theory called White's theory of spirituality and spiritual self-care (WTSSSC) was developed. To begin to test this mid-range theory, empirical indices of many of the main concepts were identified from prior studies and one new instrument (the Spiritual Self-Care Practice Scale) was developed. Hypothesized relationships among the main concepts …
