Effects Of Chronic Ethanol Exposure On Stress Coping Style And Genetic States Of Zebrafish (Danio Rerio), Alexander Goodman 2019 University of Nebraska at Omaha

Effects Of Chronic Ethanol Exposure On Stress Coping Style And Genetic States Of Zebrafish (Danio Rerio), Alexander Goodman

Student Research and Creative Activity Fair

Neurotransmitter systems are important in regulating the stress response. If a behavioral response is disproportional to a stressor it is characterized as anxiety-like behavior. Many anxiolytic compounds, such as ethanol, increase stressor engagement, but how these compounds interact with an organism on a neurogenetic level is less understood. In this study, I assessed the impact of chronic ethanol treatment on behavior and gene expression of GABAAreceptors subunits on two strains of zebrafish. Each strain was selectively bred to display the proactive or reactive stress coping style where proactive individuals will actively engage a stressor more than reactive individuals ...


Investigating Comt Influence On The Proactive-Reactive Stress Coping Axis In Zebrafish, Sean T. Bresnahan, Ryan Y. Wong 2019 University of Nebraska at Omaha

Investigating Comt Influence On The Proactive-Reactive Stress Coping Axis In Zebrafish, Sean T. Bresnahan, Ryan Y. Wong

Student Research and Creative Activity Fair

Individuals of the same species often display differences in correlated suites of behaviors which are made conspicuous when challenges – stressful, fear-inducing, etc. – are presented. In many species, a specific suite of behaviors (risk-aversion, aggression, exploration, learning, and memory) characterize an alternative set of stress coping styles (proactive and reactive). Such behaviors are regulated in the brain by specific neurotransmitters along with proteins that regulate them. One neurotransmitter regulator protein, catechol-O-methyltransferase (COMT) shows higher baseline whole-brain expression in proactive relative to reactive animals. However, it is not known whether its expression is a cause or a consequence of the stress coping ...

The Effects Of Ocular Dominance On Visual Processing In College Students, William Alexander Holland 2019 James Madison University

The Effects Of Ocular Dominance On Visual Processing In College Students, William Alexander Holland

James Madison Undergraduate Research Journal (JMURJ)

The role of ocular dominance in processing visual memory and analytic tasks is unknown. Research has variably showed both significant effects and no effect of ocular dominance on visual perception, motor control, and sports performance. The goal of this study was to determine if there is a relationship between ocular dominance and visual processing under a variety of computer gaming tasks. This was accomplished by first determining subjects’ ocular dominance through the Miles test, and then examining the subjects’ visual performance on four different Lumosity games under three conditions: left eye, right eye, and both eyes. Results suggest a relationship ...


Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan 2019 CUNY Hunter College

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan

School of Arts & Sciences Theses

The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside ...

Characterization Of G-Protein Coupled Receptors In Pain, Depression And Anxiety, Neil Lax 2018 Duquesne University

Characterization Of G-Protein Coupled Receptors In Pain, Depression And Anxiety, Neil Lax

Electronic Theses and Dissertations

Chronic pain and major depressive disorder are widespread conditions in the world. Interestingly, these conditions often occur comorbidly, with each individual disease amplifying the symptoms of the other. A significant amount of preclinical research in pain and depression focuses on G-protein coupled receptors (GPCRs), implying that GPCRs may be useful in treating this comorbidity. Our efforts have sought to characterize several poorly understood GPCRs, including the serotonin receptor subtypes 2C and 7 (5-HT2CR and 5-HT7R) and metabotropic glutamate receptor 5 (mGluR5), along with more well-known GPCRs such as the mu opioid receptor (MOR), and the role that they play in ...


Role Of Trkb-Signaling In Taste Development And Function., Jennifer Rios-Pilier 2018 University of Louisiville

Role Of Trkb-Signaling In Taste Development And Function., Jennifer Rios-Pilier

Electronic Theses and Dissertations

In the geniculate ganglion, taste neurons likely differentiate into subtypes during development, but very little is known about how these neurons are defined molecularly or how they differentiate. Embryonically, geniculate neuron development is regulated by the growth factor, brain ­derived neurotrophic factor (BDNF). Postnatally, BDNF becomes restricted to subpopulations of taste receptor cells with specific functions, primarily sour responding. I hypothesized that during development, the receptor for BDNF, tropomyosin kinase B receptor (TrkB), also becomes restricted to a neuronal subset. I used transgenic mouse models to label and quantify both geniculate sensory neurons (Phox2b+), and those expressing TrkB (GFP) across ...


Hypothalamic Circuits In The Control Of Feeding And Emotional Behaviors, Leandra Mangieri 2018 The University of Texas M D Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Hypothalamic Circuits In The Control Of Feeding And Emotional Behaviors, Leandra Mangieri

UT GSBS Dissertations and Theses (Open Access)

Feeding results from the integration of both nutritional and affective states, and is guided by complex neural circuitry in the brain. The hypothalamus is a critical center controlling feeding and motivated behaviors. We found that targeted photostimulation of projections from the lateral hypothalamus (LH) to the paraventricular hypothalamus (PVH) in mice elicited voracious feeding and repetitive self-grooming behavior. GABA neurotransmission in the LH->PVH circuit mediated the evoked feeding behavior, and elicited behavioral approach, whereas glutamate release promoted repetitive self-grooming, which was stress-related in nature. Optogenetic inhibition of LHGABA ->PVH circuit reduced feeding after fasting, whereas photostimulation abruptly stopped ...


Behavioral Insights Into Nociceptor Function: A Systematic Approach To Understanding Postsurgical And Neuropathic Pain Mechanisms In Rats, Max Odem 2018 The Univesity of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Behavioral Insights Into Nociceptor Function: A Systematic Approach To Understanding Postsurgical And Neuropathic Pain Mechanisms In Rats, Max Odem

UT GSBS Dissertations and Theses (Open Access)

Postsurgical and neuropathic pain are each clinically common, and often associated with ongoing pain. Ongoing pain has been linked to ongoing activity (OA) in human C-fiber nociceptors. Preclinical studies using rodent neuropathic models have concentrated on allodynia driven by OA generated in non-nociceptive Aβ fibers, but little attention has been paid to postsurgical pain in sham controls or to C-fiber nociceptor OA promoting ongoing pain.

Operant assays that reveal negative motivational and cognitive aspects of voluntary pain-related behavior may be particularly sensitive to pain-related alterations. In the mechanical conflict (MC) test, rodents can freely choose to escape from a brightly ...


Pornography’S Effect On The Brain: A Review Of Modifications In The Prefrontal Cortex, Kendra J. Muller 2018 Brigham Young University

Pornography’S Effect On The Brain: A Review Of Modifications In The Prefrontal Cortex, Kendra J. Muller

Intuition: The BYU Undergraduate Journal in Psychology

Pornography use has exponentially increased in the past 10 years. Most believe pornography use is largely a harmless behavior. Although sexuality is innate, hyper-sexual behavior, such as pornography use, has become increasingly commonplace. Addiction research has found that long-term substance addiction contributes to changes in brain volume (Hong et al., 2013; Zhou et al., 2011). Recent studies have shown that behavioral addictions also have similar volume loss as substance abuse (Hong et al., 2013). Research has shown that the particular area most affected is the prefrontal cortex (Hong et al., 2013). The prefrontal cortex, which oversees regulating self-control, decreases in ...


Cannabinoid Transmission In The Basolateral Amygdala Modulates Prefrontal Cortex And Ventral Hippocampal Activity, Brian J. Pereira 2018 The University of Western Ontario

Cannabinoid Transmission In The Basolateral Amygdala Modulates Prefrontal Cortex And Ventral Hippocampal Activity, Brian J. Pereira

Electronic Thesis and Dissertation Repository

The cannabinoid system is important for maintaining neuron-to-neuron communication within the mammalian brain. One of the most commonly used substances to alter the cannabinoid system is cannabis. Individuals who are exposed to cannabis report having dissociable effects; both positive and negative. High amounts of THC have been commonly associated with the negative effects of cannabis, whereas CBD can be used to counter these. Pre-clinical evidence suggests that the combination of the two compounds can produce a therapeutic benefit for individuals who are susceptible to the effects of THC. The present study investigates whether the combination of THC+CBD can prevent ...


Measuring The Impact Of A Weeklong Fall Break On Stress Physiology In First Year Engineering Students, Ayesha Khan, Heather Poole, Elliott A. Beaton 2018 McMaster University

Measuring The Impact Of A Weeklong Fall Break On Stress Physiology In First Year Engineering Students, Ayesha Khan, Heather Poole, Elliott A. Beaton

The Canadian Journal for the Scholarship of Teaching and Learning

Canadian post-secondary institutions are increasingly introducing a fall break into their term calendars, with the stated goal of reducing student stress and improving academic success. We conducted a pilot study around the time of this fall break during which we collected saliva samples to measure the ratio of two metabolic hormones (cortisol and dehydroepiandrosterone (DHEA)) from first-year male engineering students in order to document possible changes in their stress levels before and after the break. Participants self-identified a particular day in the week prior to the break that they considered to be most stressful, followed by a day in the ...


Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones 2018 The Graduate Center, City University of New York

Curcumin Inhibits The Ikk:Nf-Kappa B Pathway In Neural Fear Circuits, Miguel A. Briones

All Dissertations, Theses, and Capstone Projects

The study of how the brain acquires fearful memories has attracted considerable experimental attention, due in part to the promise of discovering novel therapeutic approaches for psychiatric disorders that are characterized by unusually strong and persistent traumatic memories. In recent years, extensive research has focused on studying the neural and molecular mechanisms by which fear memories are acquired, stored, and retrieved in the brain. Once acquired, fear memories may be attenuated using one of 2 procedures: 1) fear extinction, which involves repeated presentation of the fear-arousing stimulus in the absence of an aversive consequence, or 2) interference with the reconsolidation ...


Dietary Curcumin Promotes Resilience To Chronic Social Defeat Stress In A Highly Susceptible Mouse Strain, Antonio V. Aubry 2018 The Graduate Center, City University of New York

Dietary Curcumin Promotes Resilience To Chronic Social Defeat Stress In A Highly Susceptible Mouse Strain, Antonio V. Aubry

All Dissertations, Theses, and Capstone Projects

Chronic exposure to stress is a risk factor for the development of major depression and post traumatic stress disorder in humans and induces depressive- and anxiety-like phenotypes in rodents. However, there are few pharmacological interventions available that effectively treat maladaptive responses to chronic stress in the clinical setting. One therapeutic agent that has recently shown promise in treating psychiatric disorders is curcumin, a yellow-pigmented polyphenol compound found in the turmeric plant. Curcumin has been shown to prevent the development of stressed-induced depressive-like behavior in rodents and reduce symptoms of depression in clinically diagnosed patients. In this dissertation, I investigated whether ...


Characterizing The Cognitive And Emotional Effects Of Delta-9-Tetrahydrocannabinol In Distinct Hippocampal Sub-Regions, Dinat Khan 2018 The University of Western Ontario

Characterizing The Cognitive And Emotional Effects Of Delta-9-Tetrahydrocannabinol In Distinct Hippocampal Sub-Regions, Dinat Khan

Electronic Thesis and Dissertation Repository

The objective of this study is to determine the potential differential effects of THC in the DH or VH sub-regions, as well as the upstream effects on PFC neuronal activity and oscillations. Rodents used for electrophysiology were infused with THC or vehicle in the DH or VH regions, combined with PFC recordings. Additionally, a battery of behavioural paradigms was performed. Deficits in short-term memory when THC was infused into both regions was observed, however working memory was impaired with VH infusions only. This could be due to THC-induced dysregulation in the PFC, as beta oscillations were significantly decreased selectively in ...


An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi 2018 CUNY Hunter College

An Investigation Of Vocal Learning Propensity In Zebra Finch (Taeniopygia Guttata), Tatsuya Hayashi

School of Arts & Sciences Theses

The investigator attempted to predict the vocal learning propensity from either family pedigree or early vocal babbling (subsong). Pedigree trees suggest the possibility that vocal learning ability may depend on family. We failed to predict vocal learning propensity from subsong, but suggested that subsong may influence vocal learning outcome.


Examining The Associative Learning And Accumbal Dopaminergic Mechanisms Of Caffeine Reinforcement, Curtis Bradley 2018 East Tennessee State University

Examining The Associative Learning And Accumbal Dopaminergic Mechanisms Of Caffeine Reinforcement, Curtis Bradley

Electronic Theses and Dissertations

Caffeine is the most consumed psychoactive substance in the world, and most caffeine consumption in coffee and energy drinks is intended to produce a psychoactive effect. However, caffeine is not a primary reinforcer in preclinical paradigms – non-human species do not reliably take the drug to produce a psychoactive effect. However, caffeine is a ‘reinforcement enhancer’ in preclinical models; the effects of caffeine increase the motivation to obtain other non-drug reinforcers. The overall goal of this project was to determine if these reinforcement enhancing effects of caffeine could promote caffeine self-administration and to subsequently investigate the behavioral and neurochemical underpinnings of ...


Chemosensory Communication And Neural Substrates Of Social Behavior In The African Cichlid Fish, Astatotilapia Burtoni, Karen Elizabeth Field 2018 Louisiana State University and Agricultural and Mechanical College

Chemosensory Communication And Neural Substrates Of Social Behavior In The African Cichlid Fish, Astatotilapia Burtoni, Karen Elizabeth Field

LSU Doctoral Dissertations

Social animals must constantly assess their environment to make appropriate decisions. In several fish species, chemosensory signaling is crucial for social communication, conveying information on sex, reproductive state, and social status. Despite its importance in fishes, relatively little is known about how they employ chemical signaling, with only a few of the over 30,000 extant species investigated thus far. Further, there is a scarcity of information about where and how socially-relevant chemosensory signals are processed in the brain of fishes, or how chemosensory signals are integrated with other senses to elicit appropriate behaviors. For my doctoral research, I examined ...
