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

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 May 2017

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 …

The Effects Of Arginine Vasopressin On Maternal Behavior And Aggression In Peromyscus Californicus Mothers, Nathaniel Ng Jun 2015

The Effects Of Arginine Vasopressin On Maternal Behavior And Aggression In Peromyscus Californicus Mothers, Nathaniel Ng

Honors Projects

Research studies since the 1950s have shown that a chemical within the brain called arginine vasopressin (AVP) is associated with the modulation of many different social behaviors in mammals. Some of these behaviors are related to parenting, such as parental care initiation, aggression, social recognition, depression and anxiety. Understanding the physiology behind AVP regulation could allow for the creation of new therapies for treating human social disorders, such as using an AVP receptor antagonist to attenuate anxiety. This project examines how neural injections of AVP and an AVP receptor antagonist affect both maternal care and aggression in female Peromyscus californicus …


An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham Jan 2015

An Exploration Of The Wheel-Induced Feeding-Suppression, Stephen Benjamin Peckham

Theses and Dissertations (Comprehensive)

Anorexia nervosa is an enigmatic human condition typified by food-restriction that is often accompanied by extensive exercise. This has been modeled in rats in the wheel-induced feeding-suppression (WIFS) model. In this model, animals are given access to a running-wheel, which induces a volitional drop in food-consumption. Short periods of wheel access have induced a feeding-suppression which is effectively reversed by chlorpromazine administration (Adams et al., 2009). Recent attempts at replicating Adams et al.’s (2009) feeding-suppression have, however, been unsuccessful (Peckham et al., 2013). These attempts raised questions as to whether or not the existing methodology is most effective at suppressing …


Effects Of 5-Hydroxytryptamine 2c Receptor Agonist Mk212 And 2a Receptor Antagonist Mdl100907 On Maternal Behavior In Postpartum Female Rats, Weihai Chen, Qi Zhang, Wenxin Su, Yu Yang, Jing Qiao, Nan Sui, Ming Li Feb 2014

Effects Of 5-Hydroxytryptamine 2c Receptor Agonist Mk212 And 2a Receptor Antagonist Mdl100907 On Maternal Behavior In Postpartum Female Rats, Weihai Chen, Qi Zhang, Wenxin Su, Yu Yang, Jing Qiao, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

Maternal behavior in rats is a highly motivated and well-organized social behavior. Given the known roles of serotonin (5-HT) in emotion, motivation, social behavior, and major depression – and its known interaction with dopamine – it is likely that serotonin also plays a crucial role in this behavior. So far, there are surprisingly few studies focusing on 5-HT in maternal behavior, except for maternal aggression. In the present study,we examined the effects of 5-HT2C receptor agonism and 5-HT2A receptor antagonism on maternal behavior in postpartum female rats.We hypothesized that activation of 5-HT2C receptors and blockade of 5-HT …


Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil Jan 1969

Some Parameters Of The Second-Order Conditioning Of Fear In Rats, Alan Kamil

Papers in Behavior in Biological Sciences

The effects of CS1 duration, partial reinforcement, and trace conditioning on second-order conditioned suppression were investigated, employing 64 rats as Ss. In Experiment 1, the clearest second-order conditioning was obtained when CS1 duration was the same during both the first- and the second-order conditioning phases of the experiment. In Experiment 2, somewhat better second-order conditioning was obtained when first-order conditioning had been under conditions of partial reinforcement, delay CS-US pairing. In neither experiment were CS1 suppression and CS2 suppression during second-order testing well correlated. This aspect of the results raised the question of the influence of nonclassical conditioning factors on …
