Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Doctoral Dissertations
A mild traumatic brain injury (mTBI), also known as a concussion, is defined as an injury that results in an alteration of consciousness or mental status. Previous studies have shown mTBI populations experience a number of chronic (> 1 year) symptoms, such as sleep disturbances (e.g., sleep stage alterations), mood alterations (e.g., depressive symptoms), and cognitive alterations (e.g., poor concentration). The three chapters of this dissertation sought to explore these long-term sequelae and the possible interrelations between them. In the first experiment, sleep-dependent memory consolidation of neutral stimuli was probed in a chronic mTBI sample and a control, uninjured sample. …

The Effects Of Testosterone On Emotional Processing In Male Rhesus Monkeys (Macaca Mulatta), Hanna M. King
Masters Theses 1911 - February 2014
The effects of testosterone (T) extend beyond reproductive behavior to the areas of cognitive and emotional functioning. While T effects on cognition have been extensively investigated, less is known about the role of T in the processing of emotional stimuli. Considering the role that T plays in aggressive behavior and dominance status, it is of particular interest to determine whether T modulates the processing of social threat. Due to their similarities to humans in brain organization, reproductive endocrinology and affective regulation, rhesus monkeys (macaca mulatta) provide an excellent model to investigate this relationship. In a within-subjects design, six male rhesus …
