Validation Of The 40 Hz Auditory Steady State Response As A Pharmacodynamic Biomarker Of Evoked Neural Synchrony, Muhammad Ummear Raza
Validation Of The 40 Hz Auditory Steady State Response As A Pharmacodynamic Biomarker Of Evoked Neural Synchrony, Muhammad Ummear Raza

Schizophrenia is a troubling and severe mental illness that is only incompletely treated by currently available drugs. New drug development is hindered by a scarcity of functionally relevant pharmacodynamic biomarkers that are translatable across preclinical and human subjects. Although psychosis is a major feature of schizophrenia, cognitive and negative symptoms determine the long-term functional outcomes for patients. Stimulus-evoked neural synchrony at gamma (~ 40 Hz) frequency plays an important role in the processing and integration of sensory information. Not surprisingly, schizophrenia patients show deficits in gamma oscillations. NMDA receptor (NMDAR) activation on fast-spiking parvalbumin-positive interneurons is deemed important for the …

Pesticide testing is of practical interest in various areas of today’s world due to their prevalence and toxicity. These areas include agriculture, environmental, chemical plants, and many others. Herbicides, like Roundup, contain secondary amines such as glyphosate. The ability to detect secondary amines could offer a method for glyphosate detection in agricultural and environmental samples. Secondary amines can interact with metal complexes through electron charge transfer. Such interactions can cause a change in the metal’s electron configuration and energy state and can be seen in the UV-Vis spectrum. Metal phthalocyanines (MPc’s) and other organometallic complexes have been of interest for …
Behavioral Effects And Neurobiological Mechanisms Of 3-Aminobenzimide In A Rodent Model Of Chronic Psychological Stress, Liza Wills
Electronic Theses and Dissertations
Major depressive disorder (MDD) is a leading cause of disability worldwide, with a lifetime prevalence rate of approximately 20%. Inadequate pharmacological treatment methods for MDD are a significant debilitating factor. Patient estimates suggest that the treatment resistance rate for pharmacological interventions is over 30%. Postmortem analyses of human tissue of individuals diagnosed with MDD have shown an increase in Poly (ADP-ribose) polymerase 1 (PARP-1) mRNA gene expression in prefrontal cortical white matter when compared to psychiatrically normal brain tissue. In order to further investigate this issue, the present study used the social defeat stress/chronic unpredictable stress (SDS + CUS) rodent …
Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz
Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz
Electronic Theses and Dissertations
Prenatal opioid exposure has been studied in relation to infants' medical outcomes. However, large gaps exist in the literature supporting early identification of atypical neurobehavior and motor development of infants with prenatal opioid exposure. The purpose of the study was to investigate whether prenatal opioid exposure has a negative influence on a newborn infant’s neurobehavior and motor development to aid in the early identification of potential delays. Using a prospective quasi experimental design, infants motor development using the Test of Infant Motor Performance (TIMP) and neurobehavior using the NICU Neonatal Network Scale (NNNS) was assessed on 58 infants in a …
Operatic Mysticisms: Mountains, Deserts, Waterscapes, Andrew Demczuk
Operatic Mysticisms: Mountains, Deserts, Waterscapes, Andrew Demczuk
Electronic Theses and Dissertations
Operatic Mysticisms: Mountains, Deserts, Waterscapes examines the ways we encounter environments as readers/viewers of operas, literature, film, and sound recordings, and how each medium requires different detail-gathering techniques. Respective to the previously mentioned mediums, Sun & Sea (2017), Mount Analogue (1952), El Mar La Mar (2017), and Energy Field (2010) are analyzed by engaging with environmental media studies and invention. Reflecting the nature of each landscape—summits of mountains, aporias of deserts, and mysteries of waterscapes—an elemental approach is taken in investigating how these spaces may be noticed, internalized, recorded, and traversed by both the artist and viewer. …
