Numerical Cognition And Autism Spectrum Traits In Adults, Benjamin Covington Dec 2021

Numerical Cognition And Autism Spectrum Traits In Adults, Benjamin Covington

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evidence suggests that individuals with high-functioning autism spectrum disorder (ASD) may be particularly inclined toward math proficiency, especially in adulthood. There is also evidence, however, that many of those with an ASD struggle in math as children compared to their typically-developing peers. These ostensibly inconsistent findings may indicate that individuals with an ASD struggle with number sense, a precursor to formal math, rather than with formal math per se. This account is compatible with evidence of a specific form of neural dysregulation, excitatory/inhibitory imbalance, in ASD that results in reduced signal-to-noise ratios (SNR) for processes that occur in downstream …


Fatty Acid Induced Insulin Resistance In The Brain, Hyoung Il Oh May 2013

Fatty Acid Induced Insulin Resistance In The Brain, Hyoung Il Oh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The prevalence of obesity is rapidly increasing; it is now one of the most serious public health problems worldwide. Obesity is thought to reflect the interaction between genetics and modern life style. In particular, high fat diets (HFD) are considered as a major contributing factor to the development of obesity and type 2 diabetes as well as other metabolic disorders such as cardiovascular disease, Alzheimer’s disease and some types of cancer. Recently, it has been suggested that insulin actions in the brain are important in the regulation of energy homeostasis and peripheral metabolism.

Targeting Fatty Acid-Activated Pathways In The Somatosensory System, Tian Yu May 2010

Targeting Fatty Acid-Activated Pathways In The Somatosensory System, Tian Yu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Given the dramatic rise in obesity and the diseases linked with it, it is becoming increasingly important to understand the mechanisms that underlie the body's ability to recognize fat. The chemoreception of dietary fat in the oral cavity has largely been attributed to activation of the somatosensory system that relays the textural properties of fat. However, the ability of fatty acids, which are believed to represent the proximate stimulus for fat taste, to activate trigeminal ganglionic neurons has remained unexplored. In general, my research has provided the first evidence of fatty acids activating the somatosensory system by increasing the intracellular …
