The Role Of Androstane Neurosteroids In Alcohol-Mediated Social Behavior, Jason J. Paris Jan 2011

The Role Of Androstane Neurosteroids In Alcohol-Mediated Social Behavior, Jason J. Paris

Legacy Theses & Dissertations (2009 - 2024)

Androgenic steroids, such as testosterone, may influence the propensity for aggression in both people and animals. Some of testosterone's effects on aggression may be due, in part, to its metabolic products that are 5á-reduced and 3á-hydroxylated to form, 3á-androstanediol (3á-diol), which can also enhance aggression in mice. Notably, alcohol (EtOH) consumption facilitates aggression in people and animals, particularly among those predisposed to act aggressively. In rats, EtOH can increase 3á-diol in prefrontal cortex, which may facilitate aggression. The present work aimed to elucidate the role of 3á-diol for EtOH-enhanced aggression. We hypothesized that EtOH would enhance inter-male aggression, social dominance, …

A Functional Study Of Ampa And Kainate Receptors, Yan Han Jan 2011

A Functional Study Of Ampa And Kainate Receptors, Yan Han

Legacy Theses & Dissertations (2009 - 2024)

The ionotropic glutamate receptors are localized in the pre- and postsynaptic membrane of neurons and mediate the majority of fast excitatory synaptic transmission. These receptors are divided into three subtypes: α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), kainic acid, and N-methyl-D-aspartic acid (NMDA) receptors. My thesis work focused on AMPA and kainate receptor subtypes.

Physiology Of Yawning : Proximate Mechanisms Supporting An Ultimate Function, Melanie Lee Shoup-Knox Jan 2011

Physiology Of Yawning : Proximate Mechanisms Supporting An Ultimate Function, Melanie Lee Shoup-Knox

Legacy Theses & Dissertations (2009 - 2024)

Recent research suggests that yawning functions to cool the brain during periods of mild hyperthermia. Evidence for this hypothesis is largely behavioral, and includes reports of increased yawning during increases in ambient temperature and times of stress as well as an amelioration of yawning upon nasal breathing and forehead cooling. Little research has been published on the physiological mechanisms supporting a brain cooling function, however. The current set of studies explores human and animal physiological parameters in search of evidence of brain cooling during yawning. In humans, heart rate, skin temperature, and skin conductance findings suggest that yawning involves an …

Three-Dimensional Hydrogel Cell Culture Systems For Modeling Neural Tissue, John P. Frampton Jan 2009

Three-Dimensional Hydrogel Cell Culture Systems For Modeling Neural Tissue, John P. Frampton

Legacy Theses & Dissertations (2009 - 2024)

Two-dimensional (2-D) neural cell culture systems have served as physiological models for understanding the cellular and molecular events that underlie responses to physical and chemical stimuli, control sensory and motor function, and lead to the development of neurological diseases. However, the development of three-dimensional (3-D) cell culture systems will be essential for the advancement of experimental research in a variety of fields including tissue engineering, chemical transport and delivery, cell growth, and cell-cell communication. In 3-D cell culture, cells are provided with an environment similar to tissue, in which they are surrounded on all sides by other cells, structural molecules …

The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer Jan 2009

The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer

Psychology Faculty Scholarship

Neuroscientific research methods, such as brain imaging techniques, have increasingly been applied to social cognitive research efforts and, in particular, to the study of the self. In this essay we discuss the ability of such research to shed light on the emergent, dynamic psychological phenomenon of self. Although neuroscientific tools can be useful for gaining general knowledge about associated underlying structures, a careful consideration of the methodological and theoretical issues discussed herein is necessary to avoid simplifying or reifying the self.
