Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy

University of New Orleans Theses and Dissertations

The model of basal ganglia function proposed by Albin, Young and Penney (1989) describes two anatomically independent motor pathways, the direct and indirect. However, under normal conditions striatal dopamine (DA) is required for the expression of motor behavior, and DAergic control of the two pathways (via D1 and D2 receptors, respectively) is dependent on co-activation. We tested for a possible breakdown of D1/D2 synergism using transgenic R6/1 mice bearing the human huntingtin allele (Htt). Motor stereotypy, observed prior to the onset of HD-related symptoms, was rated on a 5-point scale following activation of: A) D1 receptors alone, B) D2 receptors …

Virtual Reality As A Training Tool To Treat Physical Inactivity In Children, Adam W. Kiefer, David Pincus, Michael J. Richardson, Gregory D. Myer

Psychology Faculty Articles and Research

Lack of adequate physical activity in children is an epidemic that can result in obesity and other poor health outcomes across the lifespan. Physical activity interventions focused on motor skill competence continue to be developed, but some interventions, such as neuromuscular training (NMT), may be limited in how early they can be implemented due to dependence on the child’s level of cognitive and perceptual-motor development. Early implementation of motor-rich activities that support motor skill development in children is critical for the development of healthy levels of physical activity that carry through into adulthood. Virtual reality (VR) training may be beneficial …

Mental Illness And The Grace Of God, Laura K. Sjoquist

Bioethics in Faith and Practice

This paper will attempt to address God's grace towards those with mental illnesses. It also attempts to provide direction in response to historical church views towards this population. Through scripture, this paper seeks to emphasize the importance of seeing a person as more than what they physically appear capable of - seeing people through God's eyes.

Mindfulness And Law Enforcement: An Effective Approach To Implementing Mindfulness For First Responders, Gina White

Mindfulness Studies Theses

An increasing number of studies show that people employed as first responders in high trauma service jobs tend to experience a high level of stress, at work and after hours. Studies suggest that constant exposure to job related stress leads to both physical and mental dysregulation. This study looks at the effects of implementing mindfulness tools and techniques to those working in law enforcement. Other works on this topic report mindfulness as a successful tool to increase wellbeing to a broad spectrum of populations. The methodology used in this study was designed specifically for first responders. The data findings were …

Rat Hind Limb Nociceptive Withdrawal Response To Heat And Mechanical Stimuli Depends On Initial Position Of The Paw But Not Stimulus Location, Giavanna Verdi

Senior Honors Projects, 2010-2019

Mammals rapidly withdraw their hind limb in response to noxious stimulation, which is a protective movement known as the nociceptive withdrawal response (NWR). The NWR has been previously studied in spinalized, decerebrated and anesthetized non-human and human mammals; however, there is minimal information on the NWR in intact, unanesthetized non-human mammals.

The first specific aim was to identify the factors that determine the direction and magnitude of the NWR in intact, unanesthetized rats. Based on previous studies, we hypothesized that the location of stimulation and the initial position of the paw preceding the NWR will influence the direction and magnitude …

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 …
