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 …

This study used an emotional geographies theoretical framework to analyze the emotional dimensions of urban teacher change. Fifteen urban physical education teachers involved in a comprehensive curriculum reform project were interviewed and observed multiple times across one school year. Data were analyzed using inductive analysis, and trustworthiness measures included triangulation, peer debriefing, researcher journals, and member checks. Teachers reported that emotional dimensions related to their urban students, colleagues, and status heavily influenced their engagement in the project. The discussion section maps the emotional dimensions of these teachers' change experiences onto an emotional geographies framework that situates their experiences in change …
