Olfactory sensory neurons (OSNs) are contained within the olfactory epithelium (OE) and are responsible for detecting odorant molecules in the air. The exposure of OSNs to the external environment is necessary for their function, but it also leaves them exposed to potentially harmful elements and thus results in a high turnover rate. Despite the high turnover, the olfactory sense is maintained throughout life through the division of a population of stem cells that produce new OSNs both during normal turnover and after an injury occurs in the OE. When new OSNs are born, they must extend axons from the OE …

The geriatric population of America has grown exponentially in the past century. Health degradations and expensive medical care are characteristic of this population with many of these costs due to age-related cognitive decline. It is essential to completely understand the mechanisms of normal and abnormal aging in the search for treatments for cognitive decline. A reduction of neurogenesis is a common factor in aging, but this reduction is even more drastic in individuals experiencing cognitive decline. It is unclear what effect reduced neurogenesis has on the extracellular environment, including glial cells. In particular, changes in microglial activation could be related …

The typical ‘Western Diet’ includes a diet high in fats and sugars. This thesis explores the problems that this type of diet could have on the brain. A meta-analysis was conducted to show activated microglia count in the hypothalamus of mice after a high-fat diet. The results showed a large effect size with the included studies, showing that a high fat diet significantly increases microglia count across studies. Increased activated microglia leads to chronic inflammation in the hypothalamus, which is linked to metabolic problems like insulin resistance, leptin resistance and glucose intolerance.
