Neural Bases Of Phonological And Semantic Processing In Early Childhood, Avantika Mathur, Douglas H. Schultz, Yingying Wang Dr. Jan 2020

Neural Bases Of Phonological And Semantic Processing In Early Childhood, Avantika Mathur, Douglas H. Schultz, Yingying Wang Dr.

Center for Brain, Biology, and Behavior: Faculty Publications

During the early period of reading development, children gain phonological (letter-to-sound mapping) and semantic knowledge (storage and retrieval of word meaning). Their reading ability changes rapidly, accompanied by learning-induced brain plasticity as they learn to read. This study aims at identifying the neural bases of phonological and semantic processing in early childhood by using a combination of univariate and multivariate pattern analysis. Nineteen typically developing children between the age of five and seven performed visual word-level phonological (rhyming) and semantic (related meaning) judgment tasks during functional magnetic resonance imaging scans. Our multivariate analysis showed that young children with good reading …

Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett Jan 2020

Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett

Graduate Student Theses, Dissertations, & Professional Papers

The brain is organized as a complex network of specialized neurons that communicate via a combination of electrical and chemical signals. Our brains function to generate movement, control organ function, or direct complex behaviors; all of which requires the ability to regulate the flow of communication between circuits and networks. Work in this thesis addresses two areas of neuron communication: first, how does the release of more than one neurotransmitter from a single neuron impact behavior, and second, are matricellular proteins (MCPs) key contributors to synaptic transmission and neuron function? The conserved CCN family of MCPs have a …

How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster Jan 2020

How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster

Theses and Dissertations

A mounting body of evidence suggests that Eye Movement Desensitization and Reprocessing therapy (EMDR) is successful in reducing the impact of posttraumatic symptoms. Although the exact mechanisms of action remain unknown, theories from the psychological to the neuroscientific continue to emerge, expand, and evolve. This study will examine four of the most prominent theories to date and weigh the evidence for and against each one. It will also review, compare, and contrast the theories, evaluate the research supporting each one, and propose the most likely explanation for EMDR's success given the state of the research. Neurobiological mechanisms and correlates as …

The Effects Of Dorsal Lateral Telencephalon Lesions On Zebrafish Social Behaviour, Hailey Katzman Jan 2020

The Effects Of Dorsal Lateral Telencephalon Lesions On Zebrafish Social Behaviour, Hailey Katzman

Theses and Dissertations (Comprehensive)

Zebrafish are extremely social and aggregate in groups to form shoals. This social behaviour has been studied in the wild and in a laboratory setting, yet the mechanisms underlying the behaviour are unknown. There is evidence to suggest that the dorsal lateral telencephalon might play a role in shaping shoaling behaviour, being involved in modulating social behaviours and social reward associated with shoaling. In the current thesis, I adapted and combined several existing methods for performing lesions on the dorsal lateral telencephalon to create my own method to measure the role of the dorsal lateral telencephalon in social reward and …

The Interplay Of Progestins, Matrix Metalloproteinases, And The Aging Brain, Keyana Nicole Porter Jan 2020

The Interplay Of Progestins, Matrix Metalloproteinases, And The Aging Brain, Keyana Nicole Porter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Progestins are synthetic hormones that are designed to mimic the biological actions of progesterone. They, however, possess other pharmacological actions and properties, in addition to their progestational activities. Medroxyprogesterone Acetate (MPA) is a progestin used globally in the hormonal contraceptive, Depo Provera®, by women in their reproductive prime and is a major compound found in hormone therapy (HT) formulations used by menopausal women. MPA is used by approximately 1 in 5 adolescents and adult women in the United States who are sexually active. Globally, nearly 48 million women utilize injectable contraceptives to prevent pregnancy, with most users utilizing MPA as …
