A causative link between inner ear defects and long-term striatal dysfunction
(ProQuest Dissertations & Theses, 2013)Psychiatric disorders frequently occur with inner ear dysfunction. Although socioenvironmental variables have been proposed as risk-factors, it is unclear, whether inner ear dysfunction can directly change brain function ... -
A neural circuit underlying cocaine -seeking behavior
(ProQuest Dissertations & Theses, 2001)Drug addiction is a relapsing disease. An animal model of relapse---the "reinstatement" model---is used to study brain mechanisms underlying addiction and has good predictive-validity to human relapse. The three principal ... -
Alcohol and Substance Use in an Outpatient Multiple Sclerosis Population
(ProQuest Dissertations & Theses, 2012)Objective: Little research has examined the prevalence of alcohol and substance use in individuals with multiple sclerosis. Even less research has been done to examine the effects of alcohol and drug use on cognition in ... -
Alternate scoring of the Paced Auditory Serial Addition Test (PASAT): Evaluating strings of consecutive correct responses as predictors of cognitive functioning in patients with multiple sclerosis
(ProQuest Dissertations & Theses, 2014)Objective: The Paced Auditory Serial Addition Test (PASAT) is a commonly used test for patients with multiple sclerosis (MS). This study aimed to evaluate the usefulness of novel scoring methods of the test, including the ... -
Cognitive dysfunction in type II diabetes during hypoglycemia
(ProQuest Dissertations & Theses, 1996)This study examined the effects of hypoglycemia upon cognitive function and symptom reporting using 6 adult NIDDM patients and 5 demographically matched non-diabetic study participants. Using an insulin infusion system, ... -
Cognitive functioning in idiopathic hypogonadotropic hypogonadism
(ProQuest Dissertations & Theses, 1994)This study investigated the cognitive function of untreated, androgen and gonadotropin deficient, delayed puberty males before and after hormone replacement treatment. Ten untreated idiopathic hypogonadotropic hypogonadal ... -
fMRI in Binge Eating Disorder Participants Pre and Post Bariatric Surgery
(ProQuest Dissertations & Theses, 2015)fMRI in Female Binge Eating Disorder Participants Pre and Post Bariatric Surgery Background: Obese binge eaters are a distinct subgroup of the obese population. This study aimed to examine differences in brain activation ... -
Functional anatomy and interaction of fast and slow visual pathways in macaque monkeys*
(ProQuest Dissertations & Theses, 2008)Current dynamic models of visual processing suggest that rapid inputs to higher order ventral stream regions modulate or otherwise "frame" the processing of slower, more information-dense inputs. There is also an indication ... -
Interhemispheric Transfer of Visual Sensory Information in Autism Spectrum Disorder: A High-Density Electrical Mapping Study
(ProQuest Dissertations & Theses, 2017)Background: There is limited research on the rate of interhemispheric transfer in the ASD population. Behavioral studies indicate that interhemispheric transfer time (IHTT) is ~4 ms, although event related potentials (ERPs) ... -
Modeling human memory disorders in Drosophila melanogaster, and the restoration of memory in these models by pharmacological treatments
(ProQuest Dissertations & Theses, 2007)Fragile X syndrome and Alzheimer's disease (AD) are two of the more common diseases that limit the cognitive processes of afflicted patients worldwide. We are utilizing the model organism Drosophila melanogaster to model ... -
Neurobehavioral sequelae and brain compromise in mild head injury
(ProQuest Dissertations & Theses, 1999)The purpose of this study was to determine the role that cognitive and emotional factors play in mild head-injured patients and how these factors effect overall brain functioning, with specific focus on the relationship ... -
Neurological development of low birthweight infants
(ProQuest Dissertations & Theses, 1989)The purpose of this study was to observe the patterns of neurological recovery in low birth weight infants (less than 1500g) over the first twelve months of life. The Ameil-Tison Neurological Evaluation as well as demographic ... -
Neurophysiological mechanisms underlying object recognition in humans
(ProQuest Dissertations & Theses, 2002)Humans readily identify objects despite sub-optimal conditions affecting either the quality or quantity of the visual features defining that object. Qualitative changes may derive from alterations in an object's contrast, ... -
Neurophysiology of intermodal selective attention in humans
(ProQuest Dissertations & Theses, 1999)To function normally, primates must selectively attend a subset of the profusion of sensory information that constantly bombards the sense organs. We investigated the neural mechanisms involved in selectively attending to ... -
Neurophysiology of selective attention in the macaque visual system
(ProQuest Dissertations & Theses, 1999)I studied the neurophysiological basis of selective attention in macaque subjects by measuring the effect of attention upon visually-evoked neuronal ensemble responses in different brain visual areas. Subjects were trained ... -
Neuropsychological and Psychological Factors of Everyday Decision-Making Capacity in Alzheimer's Disease
(ProQuest Dissertations & Theses, 2012)The current study investigated Everyday Decision-Making Capacity (EDMC) related to medication management in Alzheimer's (AD) patients and Healthy Elders (HE) using the Assessment of Capacity for Everyday Decision-Making ... -
Processing of musical sounds in primary auditory cortex of the awake monkey
(ProQuest Dissertations & Theses, 2000)The studies described in this thesis aim at clarifying physiological bases of music perception. A first step towards this end requires an understanding of how perceptual attributes of complex sounds and sound sequences, ... -
Propagation of neural signals in feedforward corticocortical networks
(ProQuest Dissertations & Theses, 2014)Visual processing is accompanied by a hierarchy of cortical areas, connected by extensive feedforward, feedback and lateral projections. Processing of visual information is achieved through neuronal interactions within ... -
Role of the amygdala in drug-associated cue responses and drug-seeking
(ProQuest Dissertations & Theses, 2002)Learning and memory appear to be critical aspects of drug abuse phenomena; playing a role in craving and relapse. These studies are directed toward understanding how learning and memory systems may interact with classical ... -
Spatiotemporal electrophysiology of intra- and interhemispheric visuomotor integration: Relations with behavior
(ProQuest Dissertations & Theses, 1999)Ipsimanual and contramanual simple reaction time (RT) elicited by unilateral visual stimuli are often conceptualized in terms of a fastest route between visual system activation and motor output. Indices of brain function ...
