Attentional Dysfunction In Schizophrenia: The Effects Of Dual Orexin Receptor Blockade On An Nmda Receptor Hypofunction Model, Paige Little 2021 William & Mary

Attentional Dysfunction In Schizophrenia: The Effects Of Dual Orexin Receptor Blockade On An Nmda Receptor Hypofunction Model, Paige Little

Undergraduate Honors Theses

Hypofunctionality at the N-Methyl-D-aspartic acid receptor (NMDAR) is a commonly used model of the neurodevelopmental disorder schizophrenia due to the complex circuitry changes that follow NMDAR blockade. While these animal models are very popular for modeling the cognitive deficits seen in schizophrenia, actual treatments for this disorder remain sparse. Orexins (hypocretins) are neuropeptides that are capable of modulating activity along pathways relevant to attention, but are rarely tested for their efficacy in attenuating attentional dysfunction. This study was conducted to determine if systemic administration of the dual orexin receptor antagonist filorexant (MK-6096) was able to attenuate sustained attentional dysfunction induced …

355— Topographical Individualized Neuromarkers In The Analysis Of The Brain Functioning Of Social-Emotional Development, Maya Pellitteri, Daniella Leone, Emma Piwko, Michael Schulz, Sarina Singh, Bradley Taber-Thomas

GREAT Day Posters

Topographical Individualized Neuromarkers (TIN) are spatially arranged patterns of brain function used to develop novel brain markers of social-emotional functioning and development. The current study focuses on developing markers of risk for psychological problems in children. We are expanding on previous research that indicates the brains of shy children differ from the brains of non-shy children, where shy children present with a topographical pattern of brain function that may be considered an internally hypervigilant neuromarker (Taber-Thomas et al., 2016). Using the online software, Neurosynth, we will extend our research into neuromarkers for other disorders using publicly available data. This program …

Only by understanding the ability to take a third-person perspective can we begin to elucidate the neural processes responsible for one’s inimitable conscious experience. The current study examined differences in hemispheric laterality during a first-person perspective (1PP) and third-person perspective (3PP) taking task, using transcranial magnetic stimulation (TMS). Participants were asked to take either the 1PP or 3PP when identifying the number of spheres in a virtual scene. During this task, single-pulse TMS was delivered to the motor cortex of both the left and right hemispheres of 10 healthy volunteers. Measures of TMS-induced motor-evoked potentials (MEPs) of the contralateral abductor …


The Influence Of Autism Linked Gene Topoisomerase 3b (Top3b) On Neural Development In Zebrafish, Sydney Doolittle 2021 Georgia Southern University

The Influence Of Autism Linked Gene Topoisomerase 3b (Top3b) On Neural Development In Zebrafish, Sydney Doolittle

Honors College Theses

Autism Spectrum Disorder is a class of developmental disabilities characterized by a spectrum of social, communication, and behavioral impairments in affected individuals. Studies have shown these defects stem from abnormal brain development during critical periods during early development. The underlying genetic cause of these impairments is not well understood but is believed to be a combination of a complex pairing of genetic and environmental factors. One of the genetic factors that has been recognized to influence the phenotypic symptoms of ASD is the enzyme topoisomerase 3β (top3β.) Topoisomerases are responsible for the prevention of supercoiling during DNA replication. Top3β is …

Pornography: Social, Emotional And Mental Implications Among Adolescents, William Kelly Canady

National Youth Advocacy and Resilience Conference

This presentation will explain the historical development of pornography. It will highlight four segments: 1- Porn’s impact on brain development of reward pathways, ultimately increasing the appetite for more porn. 2- Porn can be a false substitute for real intimacy, resulting in decreased sexual satisfaction with a real person and increased verbal and physical aggression. 3- Porn promotes sex trafficking, promotes multiple sex partners and reduced STD prevention. 4- A review of interventions available to assist clients in navigating a lifestyle away from pornography.


Effects Of A Circadian Mutation On Adult Neurogenesis, Michael Bahiru 2021 University of Massachusetts Amherst

Effects Of A Circadian Mutation On Adult Neurogenesis, Michael Bahiru

Masters Theses

Rotating shift work, irregular sleep patterns and jetlag disrupt circadian rhythms, induce or aggravate disease, and produce deficits in cognitive function. Internal misalignment, a state in which abnormal phase relationships prevail between and within organs, is widely proposed to account for these adverse effects of circadian disruption. This hypothesis has been difficult to test because phase shifts of the entraining environmental cycle lead to transient desynchrony. Thus, it remains possible that phase shifts, regardless of internal desynchrony, account for adverse effects of circadian disruption. I have used the duper mutant hamster, whose locomotor activity rhythms re-entrain 5-fold faster than wild …

Department of Paediatrics and Child Health

Purpose: Neurodevelopmental disabilities are common and genetically heterogeneous. We identified a homozygous variant in the gene encoding UFM1-specific peptidase 2 (UFSP2), which participates in the UFMylation pathway of protein modification. UFSP2 variants are implicated in autosomal dominant skeletal dysplasias, but not neurodevelopmental disorders. Homozygosity for the variant occurred in eight children from four South Asian families with neurodevelopmental delay and epilepsy. We describe the clinical consequences of this variant and its effect on UFMylation.
Methods: Exome sequencing was used to detect potentially pathogenic variants and identify shared regions of homozygosity. Immunoblotting assessed protein expression and post-translational modifications in patient-derived fibroblasts. …

Open Neuroscience Initiative, Austin Lim

College of Science and Health Full Text Publications

The Open Neuroscience Initiative is a free-to-use textbook

This project began as a means to overcoming the financial burden that face undergraduate neuroscience students when buying textbooks. By compiling and writing a completely free-to-access textbook that covers the foundations of a typical college introduction to neuroscience course, students would have one less obstacle to overcome in their educational career, allowing them to focus their valuable time and attention on learning rather than finances. To make this project a reality, I began with a humble tweet in May 2019 that managed to gain a tiny bit of traction among the neuroscience …


From Crib To Bench: Understanding Neonatal Opioid Withdrawal Syndrome (Nows) Using A Novel Rodent Model, Sarah Stevens 2021 Marshall University

From Crib To Bench: Understanding Neonatal Opioid Withdrawal Syndrome (Nows) Using A Novel Rodent Model, Sarah Stevens

Theses, Dissertations and Capstones

As the opioid epidemic continues to grow, opioid use among pregnant women is increasing significantly. This has led to a steady rise in the number of infants born with neonatal opioid withdrawal syndrome (NOWS). Although short-term withdrawal symptoms associated with NOWS are well characterized, there are many gaps in our understanding of the short and long-term effects of prenatal opioid exposure. In CHAPTER 1, we describe the clinical presentation, associated neurodevelopmental challenges, and current treatments of NOWS. Our current understanding of the neuropathology of NOWS is limited, and therefore further research is needed. However, current animal models are limited by …


The Role Of Vps54 In Drosophila Melanogaster Neuronal Development And Age Progressive Neurodegeneration, Emily Wilkinson 2021 University of Denver

The Role Of Vps54 In Drosophila Melanogaster Neuronal Development And Age Progressive Neurodegeneration, Emily Wilkinson

Electronic Theses and Dissertations

Vps54 is a subunit of the Golgi-associated retrograde protein (GARP) complex, which is involved in tethering endosome-derived vesicles to the trans-Golgi network (TGN). The “wobbler” mouse is the phenotypic result of a destabilizing point mutation in Vps54. This mutation causes neurodegeneration and is subsequently used as a model for human motor neuron disease. Presently, it is unclear how disruption of GARP complex function leads to motor neuron degeneration. To better understand the role of Vps54 in motor neuron development, function, and age-related neurodegeneration, we disrupted expression of the Vps54 ortholog in Drosophila and examined the impact on larval neuromuscular junction …


Using Zebrafish To Elucidate The Expression And Gene Regulatory Network Of The Genomic Screen Homeobox Transcription Factors And Bring Innovative Science Learning Experiences To West Virginia, Rebecca Ann Coltogirone 2021 West Virginia University

Using Zebrafish To Elucidate The Expression And Gene Regulatory Network Of The Genomic Screen Homeobox Transcription Factors And Bring Innovative Science Learning Experiences To West Virginia, Rebecca Ann Coltogirone

Graduate Theses, Dissertations, and Problem Reports

Central nervous system (CNS) development requires a code of regionally expressed transcription factors that impart initial neuronal cell identity, connectivity, and function. The absence of a transcription factor code would eliminate the neurodevelopmental logic producing diverse cell types in the CNS. Furthermore, early disruptions in transcription factor expression can affect later connectivity and function of neuronal circuits mediating sensory processing, defects in which are often observed as comorbid with various neurodevelopmental disorders (NDDs). Characterizing transcription factor expression and function is therefore an essential step in discerning the molecular mechanisms underlying human NDDs. genomic screen homeobox 1 and 2 (gsx1 …


Estrogen Disruption Of Hypothalamic Neural Activity, Princess Dickson 2021 Cal Poly Humboldt

Estrogen Disruption Of Hypothalamic Neural Activity, Princess Dickson

Cal Poly Humboldt theses and projects

The brain is highly dependent on the endocrine system for proper neurodevelopment, as it plays a key role in many biological processes. Bisphenol A is a chemical found in plastics that has the potential to mimic the effects of Estrogen in the body, at least weakly. People interact with plastic that contains BPA regularly, and people are at risk for exposure even before being born. The abundance of BPA, along with other exogenous estrogens, makes examining the relationship between early exposure and changes in brain activity imperative. The current study aims to establish a relationship between disrupted estrogen function and …


The Inevitability Of Collision: Creating Empathy Through Fiction, Danielle Beckman 2021 Regis University

The Inevitability Of Collision: Creating Empathy Through Fiction, Danielle Beckman

Regis University Student Publications (comprehensive collection)

While the stigma for mental illnesses has greatly declined in the last decade, there is still a disconnect between individuals without neurological illnesses and those with neurological illnesses, especially those that cause individuals to lose contact with reality. The goal of this interdisciplinary paper is to create empathy for these individuals, specifically people with schizophrenia, Alzheimer disease, and post-traumatic amnesia. Through a collection of four stories told from the perspective of these unreliable narrators, I used fiction writing techniques from the field of cognitive literary studies such as gapping and defamiliarization to create more empathy in the reader. In reading …

The Subplate And Its Role In The Gaba System In The Prefrontal Cortex, Gaeul Kyla Lee 2020 The University of Western Ontario

The Subplate And Its Role In The Gaba System In The Prefrontal Cortex, Gaeul Kyla Lee

Electronic Thesis and Dissertation Repository

During early brain development, the subplate relays thalamocortical afferents. Lesions to the subplate have been implicated in developmental abnormalities of cortical GABAergic circuits. This thesis examined the effects of subplate lesions in the prefrontal cortex of rats on the expression of GABA markers (parvalbumin and GAD67) and GABA synapse maturation [potassium-chloride cotransporter (KCC2) and sodium-potassium- chloride cotransporter (NKCC1)] with relevance to the characterization of a rat model for schizophrenia. Lesions were made on postnatal day 1 (P1). Lesioned and control rats were sacrificed between P5 and P90 and immunolabelled for parvalbumin, GAD67, KCC2, and NKCC1. We found decreased parvalbumin expression …


Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin 2020 The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin

Dissertations & Theses (Open Access)

Cells obtain cholesterol in two ways, de novo biosynthesis and uptake from circulation. While most tissues utilize both sources, eye lens and brain depend extensively on cholesterol biosynthesis due to the limited supply from circulation. Lens cell membrane consists of highest portion of cholesterol. Brain is the most cholesterol-rich organ, which accounts for 23% of total cholesterol. Genetic mutations of cholesterol biosynthesis enzymes in humans and animal models present cataracts and hypomyelinating disorders linked to neurological impairment. Yet, it remains unclear how gene expression of cholesterol biosynthesis is regulated in lens and brain. Therefore, studying cholesterol biosynthesis in both tissues …

Neurodevelopmental Mechanisms Of Adverse Trauma Outcomes In Emerging Adulthood, Olena Kleshchova 2020 The Graduate Center, City University of New York

Neurodevelopmental Mechanisms Of Adverse Trauma Outcomes In Emerging Adulthood, Olena Kleshchova

Dissertations, Theses, and Capstone Projects

Background: Exposure to traumatic stress and adversity during the formative years of development can have adverse effects on mental health, neuroendocrine stress system function, and the brain, that persist into adulthood. One candidate mechanism that might confer vulnerability to enduring adverse outcomes of early life trauma is disruption of normal brain maturation. As the brain matures, functional interactions among brain regions change until the functional brain architecture (i.e., the functional connectome) reaches a mature state in adulthood. Given that different neural circuits have distinct developmental trajectories and sensitive periods, traumatic stress at a given point in development might have …
