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 …


Cortical-Spinal Interactions In Skill Acquisition And Performance And Their Implications For Rehabilitation, Chadwick Bruno Jean Boulay Jan 2011

Cortical-Spinal Interactions In Skill Acquisition And Performance And Their Implications For Rehabilitation, Chadwick Bruno Jean Boulay

Legacy Theses & Dissertations (2009 - 2024)

Many people in the United States have motor impairments due to stroke or other central nervous system (CNS) traumas. Motor impairments also burden the U.S. economy and health care system. Current rehabilitative therapies are moderately effective but can be improved upon. Improvements to rehabilitation protocols are informed by increased understanding of the CNS including understanding interactions between different structures in the CNS and understanding CNS plasticity in response to trauma or skill acquisition.

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.


Calcium Regulation And Transmitter Release At Drosophila Larval Neuromuscular Junction, Tao He Jan 2011

Calcium Regulation And Transmitter Release At Drosophila Larval Neuromuscular Junction, Tao He

Legacy Theses & Dissertations (2009 - 2024)

Calcium ions act as the most versatile 2nd messenger and are involved in an incredibly broad spectrum of biological processes. Proper cellular Ca2+ homeostasis is paramount in maintaining normal cell growth, functions, survival and programmed death. Hence, understanding Ca2+ regulation has been a goal of and a hot topic in cutting-edge biological research for decades. Recently, the advent of a new generation of Ca2+ indicators has made a major contribution to advances in understanding Ca2+ regulation (Grynkiewicz et al., 1985). Likewise, the application of Drosophila melanogaster as an animal model has provided tantalizing clues and fueled the progress of research …


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, …
