Faculty Journal Articles
Angiotensin II (AngII) plays a key role in maintaining body fluid homeostasis. The physiological and behavioral effects of central AngII include increased blood pressure and fluid intake. In vitro experiments demonstrate that repeated exposure to AngII reduces the efficacy of subsequent AngII, and behavioral studies indicate that prior icv AngII administration reduces the dipsogenic response to AngII administered later. Specifically, rats given a treatment regimen of three icv injections of a large dose of AngII, each separated by 20 min, drink less water in response to a test injection of AngII than do vehicle-treated controls given the same test injection. …

The Effects Of Extended Access To Methamphetamine Self-Administration On Dopaminergic Markers In The Striatum, Joe Luevano
Open Access Theses & Dissertations
Methamphetamine (METH) abuse is a persistent problem in the U.S. and abroad. Escalation of METH use among independent users occurs for a variety of physiological and psychological reasons. Methamphetamine dependence may be attributed to the rewarding effect of this drug via the dopaminergic systems of the central nervous system (CNS). The presence of METH in the CNS increases synaptic release of dopamine. This increase in dopaminergic neurotransmission is thought to be directly attributed to the rewarding effects of METH. Following METH use, compensatory changes have been found to occur in the dopaminergic system during various periods of abstinence. It is …

Merely Misunderstood: Expressive, Receptive, And Pragmatic Language In Children With Disruptive Behavior Disorders, Monica L. Gremillion
LSU New Orleans Theses and Dissertations
Children with Disruptive Behavior Disorders (DBD), including Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) have poorer language skills compared to typically developing children; however, language as a potential risk factor for DBD has received little empirical attention or evaluation. Receptive, expressive, and pragmatic language skills in preschoolers with DBD were examined. Participants were 82 preschool-age children and their primary caregivers. Primary caregivers completed a semi-structured interview and symptom and language questionnaires. Preschoolers completed measures of receptive and expressive language. Results indicated that preschoolers with DBD were more impaired on receptive, expressive, and pragmatic language compared to non-DBD children. Pragmatic …

Factors That Contribute To Susceptibility Of The Placebo/Nocebo Effect In Experimentally Induced Ischemic Arm Pain, Steve T. Brewer
LSU New Orleans Theses and Dissertations
Placebo’s (positive expectancies producing positive outcomes) and nocebo’s (negative expectancies producing negative outcomes) are real and measurable effects. Real as these effects may be, predicting individuals that may be susceptible to placebo/nocebo effects has been inconsistent. The present study examined whether measures designed to assess somatization (MSPQ), catastrophizing (PCS) and childhood trauma (CTQ) would predict placebo and nocebo membership. In addition, measures designed to assess anxiety (ASI) anxiety about pain (PASS) and depression (BDI) were evaluated to determine whether anxiety or depression mediates responsiveness. The Hargreaves Thermal Withdrawal test and the submaximal effort tourniquet technique were employed as pain vehicles …

Pain Tolerance And Thresholds In Women With Dyspareunia: Do Pain And Sex Primes Have Differential Effects?, Lea Thaler
UNLV Theses, Dissertations, Professional Papers, and Capstones
Dyspareunia, defined as recurrent pain in the genital/pelvic region during sexual intercourse, is one of the most common types of female sexual dysfunction, affecting approximately 15% of women between the ages of 18 and 24. Women with dyspareunia display similar cognitive and emotional styles evidenced in other chronic pain conditions (e.g. hypervigilance for pain information, catastrophization, and negative affect); however, dyspareunia is a unique pain disorder in that it directly involves sexual functioning. This pairing of pain and sex raises the issue of conditioning. Is it possible that because intercourse is painful for women with dyspareunia, the presentation of any …

In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp
Psychology Faculty Publications
Play behavior is a fundamental and intrinsic neurobehavioral process in the mammalian brain. Using rough-and-tumble play in the juvenile rat as a model system to study mammalian playfulness, some of the relevant neurobiological substrates for this behavior have been identified, and in this review this progress. A primary-process executive circuit for play in the rat that includes thalamic intralaminar nuclei, frontal cortex and striatum can be gleaned from these data. Other neural areas that may interact with this putative circuit include amygdala, ventral hypothalamus, periaqueductal gray (PAG), and deep tectum, as well as ascending dopamine systems which participate in all …

The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge
Faculty Journal Articles
Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …

Juvenile Fischer 344 rats are known to be less playful than other inbred strains, although the neurobiological substrate(s) responsible for this phenotype is uncertain. In the present study, Fischer 344 rats were compared to the commonly used outbred Sprague-Dawley strain on several behavioral and physiological parameters in order to ascertain whether the lack of play may be related to compromised activity of brain dopamine (DA) systems. As expected, Fischer 344 rats were far less playful than Sprague-Dawley rats, with Fischer 344 rats less likely to initiate playful contacts with a playful partner and less likely to respond playfully to these …

The Effects Of Rumination, Hostility, And Distraction On Cardiovascular Reactivity And Recovery From Anger Recall In Healthy Women, Meghan K. Mclain
Psychology Theses & Dissertations
Cardiovascular reactivity and recovery following an emotional stressor may play a crucial role in mediating the relation between psychosocial factors (e.g. hostility and anger) and cardiovascular disease. Hostility has been associated with trait rumination. Trait rumination, a tendency to focus attention on negative thoughts and emotions and be prone to feelings of revenge, is not adequately captured in current measures of hostility. The current study examined whether trait rumination, indexed by the Dissipation-Rumination Scale, has an independent effect of increasing cardiovascular reactivity and prolonging cardiovascular recovery from angry events above and beyond hostility as measured by the Cook-Medley Hostility Scale. …

How Sweet Is It, Really? The Anomalous Effects Of Glucose At Retrieval, Sarah A. Gillott
Undergraduate Honors Thesis Collection
151 participants gave free recall and probed response memories for best kisses and The Lion King. Blood-glucose levels were manipulated at retrieval with glucose (50g) or saccharin (35mg) in the form of a lemonade drink. Memories for best kisses were more elaborate than memories for The Lion King. This may be due to the fact that best kiss memories were rated as more arousing than film memories. Regardless, high blood-glucose levels as a result of glucose consumption significantly impaired autobiographical kiss memory, yet enhanced semantic memory for The …

Diel Periodicity In Activity And Location In The Web Of The Common House Spider (Achaearanea Tepidariorum)., Elise Wolf
Undergraduate Honors Theses
Circadian rhythm is a type of endogenous clock that controls daily behavioral patterns in most organisms. Spiders have been shown to exhibit both circadian and non-circadian rhythms in their behaviors. This rhythmicity may allow spiders to cope with diel changes in environmental conditions. Both diurnal and nocturnal behavior have different sets of costs and benefits to a species’ survival. Achaearanea tepidariorum is one species in which potential circadian rhythmicity has never been studied. Due to its foraging behavior, it was predicted that its daily activity would be arrhythmic. We recorded the positions within the web of forty individuals throughout the …

Time-Dependent Effects Of Stress On Cocaine Conditioned Place Preference Using A Rat Model Of Posttraumatic Stress Disorder, Lily K. Helpenstell
Senior Theses
Posttraumatic Stress Disorder (PTSD) affects approximately 8% of the entire population within their lifetimes. A startling trend of co-occurring PTSD and cocaine use has surfaced among humans who express these disorders. The present study employed the rat model of PTSD, Single Prolonged Stress, to examine the effects of stress on the rewarding properties of cocaine. Place conditioning was used to specifically evaluate differences between animals that had undergone a post-stress delay of conditioning in comparison to animals that were not delayed. This delay before conditioning, or incubation period, is a time spent undisturbed in the home cage for 10-days post-stress …

The Effect Of Early Environmental Manipulation On Locomotor Sensitivity And Methamphetamine Condition Place Preference Reward, Emily Hensleigh
UNLV Theses, Dissertations, Professional Papers, and Capstones
Early life stress has drastic effects on neurological development, affecting health and well-being later in life. Instances of child abuse and neglect are associated with higher rates of depression, risk taking behavior, and an increased risk of drug abuse later in life (Chapman,D.P. 2004; Dube,S.R. 2003). This study used repeated neonatal separation of rat pups as a model of early life stress. Rat pups were either handled and weighed as controls or separated for 180 minutes per day during postnatal days 2-8. In adulthood, rats were tested for methamphetamine conditioned place preference reward and methamphetamine induced locomotor activity. Tissue samples …

Testosterone And Vasopressin In Men’S Reproductive Behavior, Eric T. Steiner
UNLV Theses, Dissertations, Professional Papers, and Capstones
One common practice used by researchers is to divide human reproduction into two major domains: mating and parenting. Adaptive problems men faced over the millennia may have produced evolutionary pressure for hormone responses and behavior that facilitate both mating and parenting, either separately or simultaneously. The sometimes competing domains of mating and parenting in men are often mediated by a number of the same hormones, such as testosterone (T) and arginine vasopressin (AVP). One aim of the current study was to examine differences in baseline levels of T and AVP between childless men who were not in an exclusive, romantic …

Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond
Psychology Honors Projects
Historically, zoos rarely feature mixed taxa exhibits including multiple primate species; the Minnesota Zoo opened such a unique four-species exhibit featuring Rock hyraxes, Red River hogs, Colobus monkeys, and DeBrazza’s monkeys in May, 2010. Because of potential problems associated with territoriality and aggression, primates in mixed-taxa exhibits are generally non-breeding. However, the DeBrazza’s monkeys at the MN Zoo are a breeding pair with a juvenile offspring. The intent of this study was to design an ethogram with the purpose of calculating the effects of a mixed taxa exhibit on the behavior of this breeding group, and to compare their behavior …

Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez
Theses Digitization Project
The purpose of this thesis was to determine the persistence of one-shot context-specific and context-independent behavioral sensitization by administering a single pretreatment injection of cocaine or saline in either the home cage or a novel test chamber on PD 19 or PD 79. In order to examine the persistence of conditioned activity, adult rats were given an injection of saline after 1, 3, or 5 abstinence days. Preweanling rats were given an injection of saline after only 1 abstinence day.

Medial Prefrontal Modulation Of The Nucleus Basalis Magnocellularis During Attention-Dependent Learning, Venuz Yadira Greenfield
Theses Digitization Project
The nucleus basalis magnocellularis (NBM) sends cholinergic projections to the neocortex. While NBM activation of the neocortex regulates attention and contributes to memory formation, the mechanisms controlling NBM activity during attention-dependent learning are not well understood. The current experiment tested the hypothesis that the mPFC is critically involved in modulating NBM activity during attention-dependent learning in rats. A total of 80 male Long-Evans rats were purchased from a commerical research animal vendor. Rats were randomly assigned to one of four controlled groups. The procedures were done by an animal technician and veterinarian in the CSUSB Social and Behavioral Science vivarium …
