The Role Of Brain Stem 5-Ht1a And Gaba-A Receptors In The Thermoregulatory Response To Hypoxic Stress, Alexander Schmidt
The Role Of Brain Stem 5-Ht1a And Gaba-A Receptors In The Thermoregulatory Response To Hypoxic Stress, Alexander Schmidt
Senior Honors Projects, 2010-2019
Sudden Infant Death Syndrome (SIDS) is a leading cause of infant mortality. Alterations in brainstem development of Serotonin (5HT) and γ-aminobutyric acid (GABA) are linked to its cause. The sympathetic premotor neurons located in the Nucleus of the Raphe Pallidus (NRP) in the brainstem have both 5-HT1A and GABA-A receptor subtypes that mediate protective cardiovascular responses to environmental stress. It is hypothesized that alteration in these receptors at the NRP will also modify protective thermoregulatory responses to hypoxic stress such as hypothermia. Using aseptic techniques, male and female Sprague-Dawley rats (230-385g) were instrumented with radiotelemetry probes to non-invasively measure core …

Rat Hind Limb Nociceptive Withdrawal Response To Heat And Mechanical Stimuli Depends On Initial Position Of The Paw But Not Stimulus Location, Giavanna Verdi

Mammals rapidly withdraw their hind limb in response to noxious stimulation, which is a protective movement known as the nociceptive withdrawal response (NWR). The NWR has been previously studied in spinalized, decerebrated and anesthetized non-human and human mammals; however, there is minimal information on the NWR in intact, unanesthetized non-human mammals.
The first specific aim was to identify the factors that determine the direction and magnitude of the NWR in intact, unanesthetized rats. Based on previous studies, we hypothesized that the location of stimulation and the initial position of the paw preceding the NWR will influence the direction and magnitude …
Complementary Multimodal Compartments In The Developing Inferior Colliculus, Roxana Behrooz
Complementary Multimodal Compartments In The Developing Inferior Colliculus, Roxana Behrooz
Senior Honors Projects, 2010-2019
The auditory system is responsible for detecting, encoding, and deciphering hearing. The inferior colliculus (IC) is a major relay hub situated in the midbrain, that is subdivided into a central nucleus, and surrounding dorsal and lateral cortices. The central nucleus of the inferior colliculus (CNIC) is organized tonotopically based on a frequency gradient and strictly processes auditory information. In contrast, recent studies show that the lateral cortex of the inferior colliculus (LCIC) is actually multimodal, receiving inputs from not just auditory sources, but also somatosensory and visual structures. The precise organization of patterned inputs to the LCIC and their development …
The Effects Of Ocular Dominance On Visual Processing In College Students, William A. Holland
The Effects Of Ocular Dominance On Visual Processing In College Students, William A. Holland
Senior Honors Projects, 2010-2019
V. Abstract
The role of ocular dominance in processing visual memory and analytic tasks is unknown. Previous research variably showed both significant effects and no effect of ocular dominance on visual perception, motor control and sports performance. Consequently, the goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the use of the Miles test, and then proceeding to examine the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right …
Mouth Exposure To Carbohydrate Prior To Exercise Possibly Impairs The Efficacy Of Carbohydrate Mouth Rinsing During Exercise, Kevin Decker
Mouth Exposure To Carbohydrate Prior To Exercise Possibly Impairs The Efficacy Of Carbohydrate Mouth Rinsing During Exercise, Kevin Decker
Masters Theses, 2010-2019
Decker K. P., M. J. Saunders, N. D. Luden, C. J. Womack, and N. J. Hladick. Mouth Exposure to Carbohydrate Prior to Exercise Possibly Impairs the Efficacy of Carbohydrate Mouth Rinsing during Exercise. Purpose: Carbohydrate mouth-rinsing (CHO-MR) during intense endurance exercise has been associated with improved cycling performance, due to neurological influences. However, prior studies have reported the efficacy of CHO-MR is attenuated following a pre-exercise meal. To determine if this outcome is related to desensitization of CHO receptors (rather than metabolic effects following digestion), this study will investigate whether CHO-MR prior to exercise influences cycling performance when CHO-MR …
