Dopamine is an important neurotransmitter produced through the catecholamine synthesis pathway that affects brain activity. Unregulated dopamine levels can lead to various diseases such as Parkinson’s Disease or attention deficit hyperactivity disorder (ADHD). Optimization of an immunohistochemistry protocol will allow for the quantification of tyrosine hydroxylase antibody, which indirectly allows for dopamine quantification in dopaminergic regions within the brain. However, the antibody concentration to give the optimal signal-to-noise ratio in IHC varies across studies. Through this experiment, I determined the concentration of tyrosine hydroxylase (TyrH) antibody for immunohistochemistry that gave the best signal-to-background noise ratio within several known dopaminergic regions …
Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, 2024 The Texas Medical Center Library
Molecular Mechanisms Of Opioid Use Disorder In Human Brain Models, Emily Mendez
Dissertations & Theses (Open Access)
Opioid use disorder (OUD) is a national and global public health crisis with no end in sight. While studies from animal models hint at widespread epigenetic and transcriptomic alterations of opioid drugs, the molecular consequences of long-term exposure to opioid drugs in human brain is still unclear, and human-centered translational models are necessary to discern the human cell type-specific effects of OUD.
Using postmortem brain Brodmann area 9 (BA9) from the UTHealth Brain Collection for Research on Psychiatric Disorders, I identified angiogenic gene networks perturbed in the RNA and protein of OUD subjects, as well as downregulation of many neuron-correlated …

Background: Neurological disorders present a unique complexity compared to other diseases, involving multiple risk factors, causes, treatments, and outcomes. These disorders often exhibit various molecular and morphological changes indicative of disruptions in cellular plasticity and resilience. The pathogenesis of many neurological disorders remains unclear, necessitating ongoing investigations. Amyotrophic lateral sclerosis (ALS) exemplifies an idiopathic and fatal neurodegenerative disease marked by the degeneration of upper and lower motor neurons. The average life expectancy post-diagnosis is a mere 36 months, primarily attributed to respiratory muscle denervation.The persistent challenges in ALS clinical trials and the absence of effective therapeutic options have intensified interest …
Exploring The Developmental Effects Of Antidepressants In Caenorhabditis Elegans, 2024 Roseman University of Health Sciences
Exploring The Developmental Effects Of Antidepressants In Caenorhabditis Elegans, Alexandra Van Stone
Annual Research Symposium
It is so important to explore the potential side effects of antidepressants especially if these side effects could lead to a future detriment to an individual’s financial and social well-being. A better understanding of these side effects in regards to human developmental issues is imperative considering issues related to mental health and depression affect a large percentage of the population. In this study, we tested if Caenorhabditis (C.) elegans could be a potential model organism to predict possible side effects associated with select antidepressants. Their developmental problems potentially encountered upon drug treatment may be encountered in humans.
Elucidating Neuroinflammation In Multiple Sclerosis By Network Analysis, 2024 Dartmouth College
Elucidating Neuroinflammation In Multiple Sclerosis By Network Analysis, Nora C. Welsh
Dartmouth College Ph.D Dissertations
Multiple sclerosis (MS) is a heterogeneous disease, differing on many variables, including disease course, sex, and overall activity. Key characteristics of the disease encompass demyelination, axonal damage, neuronal loss, glial cell activation, and the infiltration of peripheral immune cells. Molecular proxies of these functions are secreted proteins, including cytokines and immunoglobulins, which, in the central nervous system (CNS), can be secreted into the cerebrospinal fluid (CSF). A detailed analysis of these secreted proteins can offer insights into the evolving immunological and neurodegenerative features as the disease progresses. To understand the dynamic biological processes involved in MS, I used network analysis …

Harmonious Healing: A Review Of Music Therapy, A Humanities-Based Approach To Alzheimer’S Disease Treatment, Rohan K. Desai
Kentucky Undergraduate Journal for the Health Humanities
Alzheimer’s Disease (AD) is a progressive neurodegenerative disease often characterized by memory loss, confusion, and overall cognitive decline. The aging global population has, in recent years, highlighted the fundamental lack of pharmacological treatments for individuals facing an AD diagnosis. In response, a growing body of research has shifted focus to non-pharmacological humanities-based interventions. One such intervention has been music therapy (MT). Music-focused measures have shown great promise as a method of slowing cognitive decline, but mixed results in the literature warrant the need for further investigation. Often, socioeconomic barriers can limit an individual’s access to drug-related treatments, but the affordable …

Dissertations, Theses, and Capstone Projects
A series of experiments were conducted to assess the role of glutamatergic stimulation in the dorsal and ventral regions of the medial prefrontal cortex (mPFC) in both the acquisition and expression of reward-related learning using a Pavlovian conditioning paradigm, the conditioned-approach paradigm. Rats with surgically implanted cannulas were exposed to Pavlovian conditioning sessions that occurred on three alternative days (acquisition) or seven consecutive days (expression). These 60-min conditioning sessions consisted of 30 pairings of light (CS) and food pellets (US) presented under a random time schedule. After a two-day break, rats underwent a session with no CS or US and …

Exploring A Gene Panel For Parkinson’S Disease In An Egyptian Cohort, Asmaa Saeed Gabr
Theses and Dissertations
Parkinson’s disease is a highly heterogeneous disorder characterized by diverse neuropathological features, clinical presentations and progression patterns. In Egypt, Parkinson’s disease incidence rates lie outside the range reported elsewhere. The genetic background to the pathogenesis of Parkinson's disease has been postulated for a long time. However, Parkinson’s disease has never been systematically investigated in Egypt. This study aimed to explore genetic variants and interactions that are associated with the familial and sporadic forms of Parkinson's disease in an Egyptian cohort. This includes examining variants in PD-related genes, exploring the role of specific genes like MAPT and adjacent genomic regions, and …
Effects Of Transcranial Direct Current Stimulation On Metamemory Vary By Task Difficulty, 2024 The Graduate Center, City University of New York
Effects Of Transcranial Direct Current Stimulation On Metamemory Vary By Task Difficulty, Tiffanie T. Li
Dissertations, Theses, and Capstone Projects
Metamemory is broadly defined as the awareness of one’s memory and consists, in part, of a process referred to as monitoring, where one is assessing the contents of their memory. Feeling of knowing (FOK) is one metamemory monitoring judgment where one rates how strongly they believe they will remember a currently unrecalled item. Prior work has shown that HighDefinition Transcranial Direct Current Stimulation (HD-tDCS) over the dorsal lateral prefrontal cortex (DLPFC) led to greater metamemory accuracy and that HD-tDCS over the anterior temporal lobe (ATL) led to better recall for medium difficulty questions. Other work has also shown that effects …

Dissertations, Theses, and Capstone Projects
This thematic project examines the notion of self-division, particularly in terms of the conflict between cognition and metacognition, across the fields of philosophy, psychology, and, most recently, the cognitive and neurosciences. The project offers a historic overview of models of self-division, as well as analyses of the various problems presented in theoretical models to date. This work explores how self-division has been depicted in the literary works of Edgar Allan Poe, Don DeLillo, and Mary Shelley. It examines the ways in which artistic renderings alternately assimilate, resist, and/or critique dominant philosophical, psychological, and scientific discourses about the self and its …
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, 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 …
A Causal Inference Approach For Spike Train Interactions, 2024 The Graduate Center, City University of New York
A Causal Inference Approach For Spike Train Interactions, Zach Saccomano
Dissertations, Theses, and Capstone Projects
Since the 1960s, neuroscientists have worked on the problem of estimating synaptic properties, such as connectivity and strength, from simultaneously recorded spike trains. Recent years have seen renewed interest in the problem coinciding with rapid advances in experimental technologies, including an approximate exponential increase in the number of neurons that can be recorded in parallel and perturbation techniques such as optogenetics that can be used to calibrate and validate causal hypotheses about functional connectivity. This thesis presents a mathematical examination of synaptic inference from two perspectives: (1) using in vivo data and biophysical models, we ask in what cases the …
Neurochemical Signaling Of Reward-Based Learning In Ventral Tegmental Area Dopamine Neurons, 2024 The Graduate Center, City University of New York
Neurochemical Signaling Of Reward-Based Learning In Ventral Tegmental Area Dopamine Neurons, Kyla F. Wholley
Dissertations, Theses, and Capstone Projects
Ventral tegmental area (VTA) dopamine neurons signal and participate in reward-related learning. Specifically, dopamine is postulated to encode reward-related environmental stimuli to compute reward prediction errors (RPEs). It is through the computation and maintenance of RPEs that learning occurs. However, little is known about the neural mechanisms that underlie how dopamine neurons compute RPEs and facilitate reward-related learning. The present study utilized fiber photometry in conjunction with a Pavlovian reward-based task to identify how GABA inputs to VTA dopamine neurons contribute to the computation of RPEs and reward-based behavior. Activity of GABA inputs to VTA dopamine neurons increased for reward-predicting …

The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, 2024 University of Missouri-St. Louis
The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..
