Understanding the cellular mechanisms that control resistance and vulnerability to stress is an important step toward identifying novel targets for the prevention and treatment of stress-related mental illness. Dominant and subordinate animals have been shown to exhibit different behavioral and physiological responses to stress, with dominants often showing stress resistance and subordinates often showing stress vulnerability. We have previously found that dominant hamsters exhibit reduced social avoidance following social defeat stress compared to subordinate hamsters, although the extent to which stress resistance in dominants generalizes to non-social stressors is unknown. In this study, dominant, subordinate, and control male Syrian hamsters …


Using The Suprachiasmatic Nucleus As A Model System To Assess Tolerance And Withdrawal To Alcohol, Jonathan Houghton Lindsay Aug 2017

Using The Suprachiasmatic Nucleus As A Model System To Assess Tolerance And Withdrawal To Alcohol, Jonathan Houghton Lindsay

Doctoral Dissertations

Alcohol abuse induces many disorders including depression, metabolic syndrome, and sleep disturbances. The strong link between alcohol abuse and sleep problems, along with the close connection between sleep and circadian rhythms, led us to investigate ethanol’s effects on the circadian clock. Previous work has shown that acute ethanol blocks photic phase shifts in vivo and glutamatergic phase shifts in vitro. However, neural systems become tolerant to ethanol across different timeframes. Despite both ethanol tolerance and ethanol withdrawal syndrome being listed as criteria for developing alcohol use disorders, little is known about how ethanol tolerance and withdrawal induced hyperexcitability develop and …


Effects Of Language Immersion Versus Classroom Exposure On Advanced French Learners: An Erp Study, Alexandra Claire Brito Jun 2017

Effects Of Language Immersion Versus Classroom Exposure On Advanced French Learners: An Erp Study, Alexandra Claire Brito

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

University students often report making significant advances in their second language (L2) ability after immersion in a nonnative language through study abroad. The degree to which late L2 learners can become nativelike in terms of L2 performance and brain processing is unclear in second language acquisition research. The link between L2 proficiency and learning context has been characterized in previous research, yet the role of learning experience in attaining nativelike brain processing of L2 remains to be elucidated. This study contrasts learners with advanced French proficiency who have attained this level with no, little, or more immersion experience through study …
