Neural Stem Cells: Age-Dependent Outcomes During Viral Infections In The Central Nervous System, Manisha N. Chandwani
Neural Stem Cells: Age-Dependent Outcomes During Viral Infections In The Central Nervous System, Manisha N. Chandwani
Electronic Theses and Dissertations
Viral infections in the central nervous system (CNS) are associated with neurodevelopmental and neurobehavioral deficits. The outcomes of viral infections can be driven by damage and death of neurons. Neural stem cells (NSCs) play key roles in neurodevelopment, repair, and physiological brain function. During a viral infection, NSC activity can disturbed by direct infection of NSCs by the virus or by anti-viral immune response. Here, we aimed to assess whether the anti-viral immune response can impact NSC activity during an immunocompetent response in the adult brain. We utilized a transgenic mouse model of Measles virus infection where only the CNS …
Interhemispheric Communication And Lateralization In The Mouse Hippocampus, Jake Jordan
Interhemispheric Communication And Lateralization In The Mouse Hippocampus, Jake Jordan
Dissertations, Theses, and Capstone Projects
The hippocampus is essential for memory and spatial navigation. Many theories have been proposed to explain how the hippocampus contributes to cognition; however, none has fully explained relevant neurophysiological and behavioral data. Hemispheric lateralization of hippocampal function has been reported in humans and in rodents, and lateralization of hippocampal neural circuitry has been reported in rodents. Most theories of hippocampal function fail to consider the hippocampus as a bilateral structure with hemispheric differences. Further, proposed theories of hippocampal lateralization have their own limitations in explaining empirical data concerning left/right function. Little is known about communication between the hippocampi across hemispheres. …
An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings
An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings
Electronic Theses and Dissertations
Cancer patients treated with adjuvant chemotherapy often experience cognitive decline following treatment. This phenomenon, often dubbed “chemo brain” or “chemo fog” is usually temporary, but for a subset of survivors, these cognitive impairments can be long-lasting (>10 years) and negatively affect patients’ quality of life, career performance, and social fulfillment. While it is unclear what neurobiological mechanisms underlie chemotherapy related cognitive impairment, the majority of the animal literature has focused on adult neurogenesis. One process important for neurogenesis is the proliferation of new neurons within the dentate gyrus of the hippocampus. It is evident that many chemotherapy agents can …
The Role Of Forebrain Cholinergic Signalling In Regulating Hippocampal Function And Neuropathology, Mohammed Al-Onaizi
The Role Of Forebrain Cholinergic Signalling In Regulating Hippocampal Function And Neuropathology, Mohammed Al-Onaizi
Electronic Thesis and Dissertation Repository
Cholinergic dysfunction has been associated with cognitive abnormalities in a variety of neurodegenerative and neuropsychiatric disorders, including Alzheimer’s Disease (AD). Cumulative use of drugs with anticholinergic activity is associated with increased risk for dementia and AD. Also, cholinergic function has been implicated in predicting the development of key neuropathological hallmarks seen in AD. However, the relationship between cholinergic dysfunction and conservation of cognitive ability as well as neuronal cell maintenance is not fully understood. Here, we tested how information processing and distinct molecular mechanisms associated with AD are regulated by cholinergic tone in genetically-modified mice in which cholinergic transmission was …
Probing The Functional Relevance Of Reactive Hippocampal Neurogenesis In A Model Of An Alcohol Use Disorder, Chelsea Rhea Geil Nickell
Probing The Functional Relevance Of Reactive Hippocampal Neurogenesis In A Model Of An Alcohol Use Disorder, Chelsea Rhea Geil Nickell
Theses and Dissertations--Pharmacy
Alcoholism, or alcohol use disorders (AUDs), represent a major public health concern both locally and globally. Critically, excessive alcohol consumption results in neurodegeneration in brain regions such as the hippocampus which is known for its role in learning and memory. Recovery of hippocampal volume loss has been observed after prolonged abstinence, but the mechanisms underlying this process are not well understood. Adult neurogenesis is thought to contribute to this recovery since after alcohol exposure a reactive increase in adult neurogenesis is observed. This reactive neurogenesis (the process by which brain insult results in a compensatory increase in neurogenesis) may represent …
