Meaghan Perdue – ProQuest LLC, 2021
Reading is a complex task that requires integration of information across brain systems that support sensory, language and cognitive processing. Individuals vary widely in reading ability: some read almost effortlessly, while others struggle to make sense of printed text. Factors at multiple levels from genes and brain through environment…

Lewis, Gwyneth A. – ProQuest LLC, 2017
An over-arching goal in neurolinguistic research is to characterize the neural bases of semantic representation. A particularly relevant goal concerns whether we represent features and events (a) together in a generalized semantic hub or (b) separately in distinct but complementary systems. While the left anterior temporal lobe (ATL) is strongly…

Santos-Oliveira, Daniela Cristina – ProQuest LLC, 2017
Models of speech perception suggest a dorsal stream connecting the temporal and inferior parietal lobe with the inferior frontal gyrus. This stream is thought to involve an auditory motor loop that translates acoustic information into motor/articulatory commands and is further influenced by decision making processes that involve maintenance of…

Atkins, Norman, Jr. – ProQuest LLC, 2009
Intercellular signaling is vital to communication within neuronal circuits. The suprachiasmatic nucleus (SCN), the master circadian clock of mammals, contains a dense collection of neurons that align their intrinsic rhythmicity with environmental stimulus and physiological state. While peptide physiology has been demonstrated as a contributor to…

Fernandino, Leonardo F. – ProQuest LLC, 2009
The mechanisms by which the mind encodes meaning into words and reconstructs it from them has been the subject of philosophical speculations at least since Plato and Aristotle in the 4th century B.C. Our current understanding of how the brain is involved in these processes, however, only started in the 19 th century, with precise descriptions of…

Koralus, Philipp Elias – ProQuest LLC, 2010
The dissertation presents a theory of semantics and pragmatics for both language and vision. I focus on sentences including proper names, descriptions, and attitude report verbs, and on the Necker cube. I propose the Open Instruction Theory (OIT), according to which the linguistic meaning of a sentence and the semantic contribution of visual…

Chandrasekaran, Lakshmi – ProQuest LLC, 2008
Short term synaptic plasticity is a phenomenon which is commonly found in the central nervous system. It could contribute to functions of signal processing namely, temporal integration and coincidence detection by modulating the input synaptic strength. This dissertation has two parts. First, we study the effects of short term synaptic plasticity…
