Effects Of Anandamide Administration On Components Of Reward Processing, Howard C. Cromwell 2017 Bowling Green State University

Effects Of Anandamide Administration On Components Of Reward Processing, Howard C. Cromwell

Howard Casey Cromwell

Previous research has implicated the positive modulation of anandamide, an endocannabinoid neurotransmitter,on feeding behavior. Anandamide is particularly noteworthy as it acts as an endogenous ligand of the CB1receptor, the same receptor that is activated by tetrahydrocannabinol, the primary psychoactive component in Cannabis sativa. Cannabis legalization in North America has presented with a need to study endocannabinoid agonists and their effects on behavior. Much has yet to be determined in terms of the role of the endocannabinoid system in decision-making scenarios. The research presented here tested the hypothesis that anandamide wouldaugment motivation and reward processing via appetitive and ...


Therapy Dogs And The Impact On Employees In The Pediatric Medical Setting, Laine Foith 2017 Abilene Christian University

Therapy Dogs And The Impact On Employees In The Pediatric Medical Setting, Laine Foith

Electronic Theses and Dissertations

More than 40% of nurses reported experiencing significant burnout. Burnout is characterized by disengagement, cynicism, negative views of personal accomplishment and ability, and emotional exhaustion. The healthcare providers that experience burnout can possibly expect a decrease in ability to recognize/report errors, increase of negative feelings toward the patient, and decrease levels of patient satisfaction (Ernest, 2014). One of the ways Schub (2015) suggested to regulate burnout for employees was to provide psychosocial support to colleagues to reduce stress. This study is one of the first attempts to bridge the gap between the unknown correlation between qualitative and quantitative benefits ...


An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings 2017 University of Maine

An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings

Electronic Theses and Dissertations

Cancer patients treated with adjuvant chemotherapy often experience cognitive decline following treatment. This phenomenon, often dubbed “chemo brain” or “chemo fog” is usually temporary, but for a subset of survivors, these cognitive impairments can be long-lasting (>10 years) and negatively affect patients’ quality of life, career performance, and social fulfillment. While it is unclear what neurobiological mechanisms underlie chemotherapy related cognitive impairment, the majority of the animal literature has focused on adult neurogenesis. One process important for neurogenesis is the proliferation of new neurons within the dentate gyrus of the hippocampus. It is evident that many chemotherapy agents can negatively ...


How Neural Activity Shapes Decision Making: An Optogenetic Investigation Of The Neural Basis Of Mate Choice In Female Songbirds, Sarah E. Maze 2017 University of Wyoming

How Neural Activity Shapes Decision Making: An Optogenetic Investigation Of The Neural Basis Of Mate Choice In Female Songbirds, Sarah E. Maze

Honors Theses AY 16/17

The intent of this project is to gain new insight into the neural circuitry that underlies decision making through understanding the connection between sensory perception and motor action. This investigation further seeks to identify whether optogenetic manipulation of specific neurons results in a change in mate choice. In defining this connection, the end goal is to combat deleterious decision making behavior in humans, such as drug addiction. Female Bengalese finches (BFs) provide an accessible model in which to investigate the neural mechanisms of behavior. Previous studies reveal that activity in the caudal portion of the mesopallium (CM) in the female ...


A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko 2017 University of Rhode Island

A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko

Senior Honors Projects

Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a ...


Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier 2017 University of Southern Mississippi

Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier

Dissertations

Alcohol abuse is the third largest risk factor for disease world, responsible for an estimated 3.3 million deaths each year. The concomitant ingestion of alcohol and caffeine is hypothesized to increase risk factors associated with alcohol use alone by reducing subjective effects of intoxication. The zebrafish (Danio rerio) has recently garnered attention from researchers as an effective pre-clinical in-vivo animal model in behavioral pharmacology research, largely due to small size, low-cost and ease of drug delivery. A number of studies have reported the effects of alcohol and caffeine on zebrafish behavior at a variety of doses. However, the combined ...


Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan 2017 University of Arkansas, Fayetteville

Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan

Theses and Dissertations

It is well known that arginine vasotocin (AVT) in birds is involved in physiological homeostasis such as cardiovascular, osmotic regulation as well as reproductive functions. Pertinent to these physiological functions, AVT immunoreactive (-ir) neurons in the hypothalamus have been found associated with hemorrhage, dehydration, oviposition and other physiological regulation. Evidence, however, suggests that AVT also plays significant roles in modulating behavior, memory, stress, and food intake. This dissertation research addresses the latter two neuroendocrine functions of AVT in detail within the chicken brain. First, the functional role of AVT-ir neurons in conjunction with corticotropin releasing hormone (CRH)-ir neurons in ...


Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence 2017 Ursinus College

Persistent Neurobehavioral Traits In A Mouse Model Of Prenatal Ethanol Exposure, Jill M. Lawrence

Neuroscience Honors Papers

Fetal Alcohol Spectrum Disorders (FASD) effect an estimated 2% of the population, causing a range of symptoms: from craniofacial defects to inhibited cortical growth (May, et al., 2009; Murawski, et al., 2015). Impaired medial forebrain function apparent in FASD is associated with lifelong cognitive behavioral deficits, but these consequences may be avoided with early diagnosis and intervention (Streissguth, et al., 2004). Our goal is to identify early neurobehavioral abnormalities that persist into adulthood that could potentially serve as early indicators for FASD. Mouse models of prenatal ethanol exposure were developed using a voluntary drinking paradigm that introduced a sweetened ethanol ...


Tracking Behavioural And Neuronal Responses To Social Pheromones: Insights From A Drosophila Model, Justin R. Croft 2017 The University of Western Ontario

Tracking Behavioural And Neuronal Responses To Social Pheromones: Insights From A Drosophila Model, Justin R. Croft

Electronic Thesis and Dissertation Repository

If eusociality evolved through modification of pre-social mechanisms for regulating personal reproduction, then even insects like Drosophila may be vulnerable to latent effects of 'queen' pheromone. Here, I test if male fruit flies respond to a eusocial queen bee pheromone. I found that male flies were attracted to queen bee pheromone, and pheromone-treated males raised the intensity of their courting towards conspecific females. These novel observations from Drosophila suggest that male flies have the capacity to respond to queen pheromone in a manner that is comparable to the native response from male (drone) bees. I therefore optimized a nuclear factor ...

Altered sensory processing in response to novel DREADD-induced inactivation of GABA in pedunculopontine tegmental nucleus

Background: Sensory processing deficits are associated with certain psychiatric illnesses, such as schizophrenia and autism spectrum disorder (ASD). Sensory filtering and sensorimotor gating are evolutionarily conserved preattentive responses that filter and block redundant sensory stimuli that would otherwise overwhelm our brains. To date, underlying mechanisms of these deficits are undefined. Prepulse inhibition (PPI) of the ...


P35. Investigating The Effect Of Maternal Immune Activation On Sensory Filtering, Social Behaviour And Attention, Faraj Haddad 2017 Western University

P35. Investigating The Effect Of Maternal Immune Activation On Sensory Filtering, Social Behaviour And Attention, Faraj Haddad

Western Research Forum

Background

Altered brain development is associated with many neuropsychiatric disorders like Autism Spectrum Disorder (ASD) and schizophrenia. Environmental insults can interfere with neurodevelopment, and a prominent example is maternal infection during pregnancy. Epidemiological studies show that children born to mothers who were infected during pregnancy display a higher risk of developing ASD and schizophrenia, and this effect is mainly due to the maternal immune response. Polyinosinic-polycytidilic acid (Poly I:C) is a double stranded RNA molecule that mimics viral markers and elicits an immune response. When injected in pregnant rodents, this model produces offspring that exhibit core symptoms of ASD ...


Comparing Consistency Of Stress And Anxiety-Related Behaviors Across Time In Zebrafish (Danio Rerio), Matthew R. Baker, Alex Goodman 2017 University of Nebraska at Omaha

Comparing Consistency Of Stress And Anxiety-Related Behaviors Across Time In Zebrafish (Danio Rerio), Matthew R. Baker, Alex Goodman

Student Research and Creative Activity Fair

Animals are frequently faced with stressors in their environment that they must overcome to survive and reproduce. Across vertebrates, two distinct stress coping styles or ‘personalities’ have been observed known as proactive (bold) and reactive (shy). Animal personalities may be advantageous by limiting individual variation and balancing different trade-offs in unpredictable environments. When identifying animal personalities, behavioral phenotypes must be consistent and repeatable across contexts and time. Here we use selectively bred lines of shy and bold zebrafish, previously shown to have consistent divergent fear- and anxiety-related behaviors across contexts, to test the repeatability and consistency of these behaviors across ...


Assessment Of Olfactory-Based Social Recognition: Designing A Paradigm For Marmosets, Stephanie Womack 2017 University of Nebraska at Omaha

Assessment Of Olfactory-Based Social Recognition: Designing A Paradigm For Marmosets, Stephanie Womack

Student Research and Creative Activity Fair

Navigation of the social world depends largely on one’s responsiveness to social stimuli and information from a wide range of senses can be used to discriminate between individuals. Mammals use several sensory modes to communicate and respond to their surroundings, but olfaction is the dominant sense across most species. Chemosignals provide a wealth of information including sex, age, reproductive status, and individual identity. Currently, assessment of olfaction is largely limited to the habituation-dishabituation paradigm or the two-choice discrimination task used primarily in rodents. These paradigms are limited by their reliance on inherent reward of interaction with stimuli without providing ...
