Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto 2024 The Graduate Center, City University of New York

Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

The Psychology Of The Stage: Intersections Of Cognitive Science And Theatre, Ariya Selvakumar 2023 Chapman University

The Psychology Of The Stage: Intersections Of Cognitive Science And Theatre, Ariya Selvakumar

Student Scholar Symposium Abstracts and Posters

By engaging audiences in a stranger’s story, theatre often depends on emotional contagion and empathetic responses to strike interest and investment in characters and their circumstances. Mirror neuron systems are those highly tied to the activation of empathy. These neurons are brain cells that activate when we perform an action and witness an action being performed. For example, when someone is crying, a subset of neurons that fire when we cry will also fire in response to seeing this action, thus often leading to emotional contagion. With an understanding of cognitive science, we can closely examine the perspective-taking and emotion-prediction …


Short Chain Fatty Acid Combination Treatment Protects Against 6-Ohda And Wt Α-Synuclein Induced Decreases In Neurite Growth In In Vitro Models Of Parkinson’S Disease., Alex Morris 2023 Department of Biological Sciences, Munster Technological University, Cork, Ireland.

Short Chain Fatty Acid Combination Treatment Protects Against 6-Ohda And Wt Α-Synuclein Induced Decreases In Neurite Growth In In Vitro Models Of Parkinson’S Disease., Alex Morris

ORBioM (Open Research BioSciences Meeting)

Background

Parkinson’s disease (PD) is a neurodegenerative disorder characterized by dopaminergic neuron degeneration. This degeneration is partly driven by over expression of α-synuclein (α-syn) and development of α-syn aggregates known as Lewy bodies throughout the substantia nigra. As well as motor dysfunction, PD presents with several chronic gastrointestinal comorbidities, which cause a decline of gut microbial diversity and microbially derived short chain fatty acids (SCFAs). Recent in vivo studies have shown SCFAs to be neuroprotective in various degenerative disease states, suggesting that SCFAs may protect against dopaminergic degeneration.

Methods

Human neuroblastoma SH-SY5Y cells were used as a model of human …


A Multi-Modal Imaging Analysis Of Inter-Community Hub Nodes In Subjective Cognitive Decline Linking Longitudinal Hub Function Disruption To White Matter Integrity Kurtosis, Duncan Nowling 2023 Medical University of South Carolina

A Multi-Modal Imaging Analysis Of Inter-Community Hub Nodes In Subjective Cognitive Decline Linking Longitudinal Hub Function Disruption To White Matter Integrity Kurtosis, Duncan Nowling

MUSC Theses and Dissertations

Subjective Cognitive Decline (SCD) has garnered much interest as a potential identifiable preclinical stage and indicator of risk for cognitive decline in Alzheimer’s Disease and related dementias (ADRD). Identification of individuals in this stage though is difficult, as they present with objectively normal cognitive evaluation scores, relying instead upon self-report of concern about decline in cognitive abilities. The use of non-invasive in-vivo imaging methods like BOLD functional imaging and diffusion tensor have allowed for complex mapping of both the functional and structural network features unique to this condition. This study furthers this network biomarker map of SCD by investigating the …

Investigating Monodelphis Domestica As An Alternative To The Mus Musculus As An Animal Model, Cristian M. Botello, John L. Vandeberg, Mario Gil

Research Symposium

Background: Mus Musculus is one of the first and one of the most widely used animal models in current neuroscience literature (Phifer-Riley & Nachmann, 2015). However, the research community needs alternatives to rodent models to study the mammalian brain. Research is needed to see if antibodies that target tyrosine hydroxylase, which are well researched in mice, can also be used to study the Monodelphis domestica brain.

Methods: Following transcardial perfusions and brain extractions, mouse and opossum brains were processed and stained for tyrosine hydroxylase (and with Nissl). Opossum brains will then be sliced and processed using IHC methods to compare …

All-Cause And Opioid-Related Mortality Compared Between Traumatic Spinal Cord Injury And The Us General Population, Jaden Whitehead, Beatrice Ugiliweneza

The Cardinal Edge

Individuals with spinal cord injury (SCI) are susceptible to the misuse of opioids due to the introduction of these substances for pain management. There are very few studies examining the relationship between unintentional deaths caused by opioid usage following spinal cord injury. The objective of this study was to evaluate the trend of opioid-related mortality of individuals with spinal cord injury (SCI) over the years and compare these findings to the mortality rates due to opioid misuse in the general population. In this study, we used data provided by the National Spinal Cord Injury Model Systems (NSCIMS) for SCI 1999-2016 …


Automatic Analysis Of The Frequency, Vigor, And Complexity Of Spontaneous Locomotion Bouts Of Mice With Loss And Gain Of Function Of The G Protein-Coupled Receptor Smoothened In Cholinergic Neurons, Aleksandra Feshchenko 2023 The Graduate Center, City University of New York

Automatic Analysis Of The Frequency, Vigor, And Complexity Of Spontaneous Locomotion Bouts Of Mice With Loss And Gain Of Function Of The G Protein-Coupled Receptor Smoothened In Cholinergic Neurons, Aleksandra Feshchenko

Dissertations, Theses, and Capstone Projects

Locomotion, a fundamental behavior, is classically assessed using simple metrics of velocity and total distance moved in an open field. This behavior however offers rich data about the organization and breadth of actions an animal can take while only facing limitations due to the bio-mechanical constraints of the organism. Importantly, these actions are not biased towards a particular task-solution space imposed by many behavioral paradigms. Here, to analyze motor complexity in freely ambulating mice, we developed a method for the automatic and unbiased identification of locomotor bouts which we call Bout Finder (BF). This analysis utilizes Open Feld data to …


Electrophysiological Signatures Of Stress Adaptability In The Bnst-Vta Pathway, Yuka Miura 2023 The Graduate Center, City University of New York

Electrophysiological Signatures Of Stress Adaptability In The Bnst-Vta Pathway, Yuka Miura

Dissertations, Theses, and Capstone Projects

Chronic stress has detrimental effects on psychological and physiological health. Incapability to adapt to chronic stress can lead to depression, anxiety disorders, and addiction. The brain regions critical for reward processing share diverse physiological and molecular changes linked to depressive-like behaviors as a result of chronic stress. Cumulative evidence shows that counteraction or prevention of these alterations in neurons, occasionally in a projection-specific manner, can enhance stress adaptation or resilience.

Chronic stress induces various changes in the brain, including in the bed nucleus of the stria terminalis (BNST) and the ventral tegmental area (VTA). The neural projections from the BNST …


You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler 2023 The Graduate Center, City University of New York

You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler

Dissertations, Theses, and Capstone Projects

Humans have a fundamental need to form and maintain social connections, and thus experiencing social exclusion is extremely distressing as it threatens this basic human need. Individuals who are socially excluded often respond aggressively, not only towards their ostracizers but also towards innocent bystanders, with ostracism being implicated in extreme acts of violence such as school shootings. However, individual differences in behavior exist within the context of social exclusion as not everyone responds aggressively after being ostracized. Identifying risk factors for retaliatory aggressive behavior following experiences of social exclusion may facilitate the development of targeted interventions aimed at mitigating such …

Identification Of Structural Brain Alterations In Adolescents With Depressive Symptomatology, J. Bashford‑Largo, R. James R. Blair, Karina S. Blair, Matthew Dobbertin, Ahria Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology and Behavior: Faculty and Staff Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …

Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta 2023 University of Nebraska-Lincoln

Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology and Behavior: Faculty and Staff Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

Asymmetric Event-Related Potential Priming Effects Between English Letters And American Sign Language Fingerspelling Fonts, Zed Sevcikova Sehyr, Katherine J. Midgley, Karen Emmory, Phillip J. Holcomb

Communication Sciences and Disorders Faculty Articles and Research

Letter recognition plays an important role in reading and follows different phases of processing, from early visual feature detection to the access of abstract letter representations. Deaf ASL–English bilinguals experience orthography in two forms: English letters and fingerspelling. However, the neurobiological nature of fingerspelling representations, and the relationship between the two orthographies, remains unexplored. We examined the temporal dynamics of single English letter and ASL fingerspelling font processing in an unmasked priming paradigm with centrally presented targets for 200 ms preceded by 100 ms primes. Event-related brain potentials were recorded while participants performed a probe detection task. Experiment 1 examined …


Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke 2023 Seattle Pacific University

Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke

Honors Projects

Project Contrast is a video game that explores how the unique traits inherent to video games might engage reflective player responses to qualitative experience. Project Contrast does this through suspension of disbelief, avatar projection, presence, player agency in storytelling, visual perception, functional gameplay, and art. Considering the difficulty in researching qualitative experience due to its subjectivity and circular explanations, I created Project Contrast not to analyze qualia, though that was my original hope. I instead created Project Contrast as an avenue for player self-reflection and learning about qualitative experience. While video games might be just code and art on a …


The Role Of Complement In Stroke And Traumatic Brain Injury, Christine Couch 2023 Medical University of South Carolina

The Role Of Complement In Stroke And Traumatic Brain Injury, Christine Couch

MUSC Theses and Dissertations

Brain and neural injury are a non-specific disease category that includes traumatic brain injury (TBI) and stroke. Both TBI and stroke are common, costly, and leading causes of severe disability in adults. Both stroke and TBI are responsible for substantial disability in working age adults, with stroke being the second leading cause of death worldwide [1] and TBI a major cause of disability in people younger than their 40's [2]. The immune response after brain injury is multifactorial and involves both local and systemic events at the cellular and molecular level. The complement system is a component of both the …


Examining The Use Of Expressive Arts Therapies In Neurorehabilitation Treatment Planning, Rebecca J. Horner 2023 Lesley University

Examining The Use Of Expressive Arts Therapies In Neurorehabilitation Treatment Planning, Rebecca J. Horner

Expressive Therapies Capstone Theses

Those undergoing neurorehabilitation after stroke and traumatic brain injury report a diminished sense of overall wellness. This paper examines the conceivable benefits of introducing expressive arts therapies, which is the therapeutic use and combination of the visual arts, movement, drama, music, writing and other intermodal creative processes, into physical therapy and neurorehabilitation treatment planning. Expressive arts therapies have the capacity to engage with an individual’s physical, emotional, social and spiritual states concurrently. They simultaneously offer the ability to promote an increased sense of well-being, address mind-body disconnects, and process trauma non-verbally.

The sections of this narrative literature review focus on …


Automated Delineation Of Visual Area Boundaries And Eccentricities By A Cnn Using Functional, Anatomical, And Diffusion-Weighted Mri Data, Noah C. Benson, Bogeng Song, Toshikazu Miyata, Hiromasa Takemura, Jonathan Winawer 2023 University of Washington

Automated Delineation Of Visual Area Boundaries And Eccentricities By A Cnn Using Functional, Anatomical, And Diffusion-Weighted Mri Data, Noah C. Benson, Bogeng Song, Toshikazu Miyata, Hiromasa Takemura, Jonathan Winawer

MODVIS Workshop

Delineating visual field maps and iso-eccentricities from fMRI data is an important but time-consuming task for many neuroimaging studies on the human visual cortex because the traditional methods of doing so using retinotopic mapping experiments require substantial expertise as well as scanner, computer, and human time. Automated methods based on gray-matter anatomy or a combination of anatomy and functional mapping can reduce these requirements but are less accurate than experts. Convolutional Neural Networks (CNNs) are powerful tools for automated medical image segmentation. We hypothesize that CNNs can define visual area boundaries with high accuracy. We trained U-Net CNNs with ResNet18 …
