Cacna1g Transcript Knockdown Analysis Via In Situ Hybridization, Jennifer (Shih-En) Chen
Cacna1g Transcript Knockdown Analysis Via In Situ Hybridization, Jennifer (Shih-En) Chen
Undergraduate Honors Theses
The pedunculopontine nucleus (PPN) comprises the mesencephalic locomotor region (MLR) of the midbrain. It contains glutamatergic, cholinergic, and GABAergic interneurons, but only glutamatergic neurons influence locomotion, which is our focus here. The PPN receives upstream and downstream input from the basal ganglia. It projects to the reticular formation of the brainstem, which connects to the spinal cord. The PPN is involved in a wide range of physiological and behavioral processes, but our focus is locomotion. We hypothesize that the PPN influences the reticular activating system (RAS) of the medulla and thus the central pattern generators (CPG) in the spinal cord …

Role Of Synaptic Inhibition In The Coupling Of The Respiratory Rhythms That Underlie Eupnea And Sigh Behaviors, Daniel S. Borrus, Cameron J. Grover, Gregory D. Conradi Smith, Christopher A. Del Negro
Arts & Sciences Articles
The preBötzinger complex (preBötC) gives rise to two types of breathing behavior under normal physiological conditions: eupnea and sighing. Here, we examine the neural mechanisms that couple their underlying rhythms. We measured breathing in awake intact adult mice and recorded inspiratory rhythms from the preBötC in neonatal mouse brainstem slice preparations. We show previously undocumented variability in the temporal relationship between sigh breaths or bursts and their preceding eupneic breaths or inspiratory bursts. Investigating the synaptic mechanisms for this variability in vitro, we further show that pharmacological blockade of chloride-mediated synaptic inhibition strengthens inspiratory-to-sigh temporal coupling. These findings contrast …
Mercury Exposure And Chronic Food Stress Elevate Corticosterone In Blood But Not Feathers, Casey Lee Mclaughlin
Mercury Exposure And Chronic Food Stress Elevate Corticosterone In Blood But Not Feathers, Casey Lee Mclaughlin
Dissertations, Theses, and Masters Projects
Bird abundance in North America has declined by almost 30% in just the past 50 years. It is crucial that we understand the many factors contributing to declines, including the impacts of environmental contaminants. Mercury is a persistent and global neurotoxic contaminant of aquatic systems that will continue to increase in the environment as anthropogenic activities and climate change accelerate its emission. The impact of mercury on songbirds, a large and diverse but declining taxon, is not well understood. I sought to better understand the effects of mercury exposure on songbirds by studying its impact on the environmentally sensitive hypothalamic-pituitary-adrenal …
The Impacts Of Acute Hypoxic Exposure And Other Concomitant Stressors On The Cardiorespiratory Physiology Of Coastal Elasmobranch Fishes, Gail Danielle Schwieterman
The Impacts Of Acute Hypoxic Exposure And Other Concomitant Stressors On The Cardiorespiratory Physiology Of Coastal Elasmobranch Fishes, Gail Danielle Schwieterman
Dissertations, Theses, and Masters Projects
This dissertation examines physiological stress responses of coastal elasmobranch fishes and investigates mechanisms that maintain oxygen delivery under stress. Elasmobranch fishes are, in general, understudied despite their susceptibility (due to K-selected life histories) to unsustainably high fishing mortality and the effects of climate change. Knowledge of physiological stress responses is, therefore, necessary to understand species-specific resilience and overall susceptibility to stressors. In Chapter II, I describe the hypoxia tolerances of clearnose skate (Rostaraja eglanteria), thorny skate (Amblyraja radiata), and summer flounder (Paralichthys dentatus, a representative teleost species) under conditions of temperatures and acidification projected to occur by the end of …
Physiological Stress And Post-Release Mortality Of White Marlin (Kajikia Albida) Caught In The U.S Recreational Fishery, Lela Sylvia Schlenker
Physiological Stress And Post-Release Mortality Of White Marlin (Kajikia Albida) Caught In The U.S Recreational Fishery, Lela Sylvia Schlenker
Dissertations, Theses, and Masters Projects
White Marlin (Kajikia albida) is a highly migratory species that occurs throughout temperate and tropical regions of the Atlantic Ocean and is the basis of a large sport fishery along the United States Atlantic coast. The single, Atlantic-wide stock is considered to be overfished, with less than one-third the spawning biomass estimated to be necessary for maximum sustainable yield. Billfish management measures adopted by the International Commission for the Conservation of Atlantic Tunas (ICCAT) and implemented in the U.S. by the National Marine Fisheries Service (NMFS), as well as increasing angler awareness of conservation, have resulted in the vast majority …

Phenotypic Properties And Intrinsic Currents Of Neurons Involved In The Neural Generation Of Mammalian Breathing, John A. Hayes
Phenotypic Properties And Intrinsic Currents Of Neurons Involved In The Neural Generation Of Mammalian Breathing, John A. Hayes
Dissertations, Theses, and Masters Projects
Breathing is essential for mammalian life. Although there is an emerging consensus that the inspiratory respiratory rhythm is generated in a lower brainstem region known as the preBotzinger Complex (preBotC), the mechanism of rhythmogenesis is still unclear. Additionally, the modulation of intrinsic currents within preBotC neurons has yet to be fully elucidated. This dissertation addresses both of these issues and relies on imaging, electrophysiological, and modeling techniques. The first chapter examines the size and composition of the preBotC. The chapter also decribes the means by which substance P (SP) excites the vast majority of preBotC neurons by illustrating the characteristics …

Metabolic Rates And Bioenergetics Of Juvenile Sandbar Sharks (Carcharhinus Plumbeus), W. Wesley Dowd
Metabolic Rates And Bioenergetics Of Juvenile Sandbar Sharks (Carcharhinus Plumbeus), W. Wesley Dowd
Dissertations, Theses, and Masters Projects
The lower Chesapeake Bay and adjacent coastal waters serve as the primary summer nursery areas for juvenile sandbar sharks (Carcharhinus plumbeus) in the Northwest Atlantic Ocean. The large population of juvenile sandbar sharks in this ecosystem benefits from increased food availability that fuels rapid growth and from limited exposure to large shark predators. Juvenile growth and survival is the most critical life history stage for sandbar sharks, and juvenile nursery grounds will continue to play an important role in the slow recovery of this stock from severe population declines due to overfishing. The goal of this study was to assess …
