The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr
Undergraduate Research Symposium
This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..
The Effects Of Floral Attributes And Conspecifics On Bumble Bee Forager Memory, Lucas Lauter, Tiffany Dinh
The Effects Of Floral Attributes And Conspecifics On Bumble Bee Forager Memory, Lucas Lauter, Tiffany Dinh
Undergraduate Research Symposium
What do bees remember about flowers? These memories are important for both bees and flowers. The bees have better foraging success and gain more nectar and pollen from flowers when they remember the most rewarding flower types. More memorable flowers will be visited more frequently, resulting in more successful pollination for the plant. At the same time, bees can also learn about flowers from other bees and may remember this information differently. We are training and testing three floral cues and a single social cue to see how the different types of cues affect their learning and memory of rewarding …
Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders
Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders
Undergraduate Research Symposium
Abstract
Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …
Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman
Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman
Dissertations
The developing brain is susceptible to extensive neurotoxicity following exposure to sedative/anesthetic drugs (SADs). Every year hundreds of thousands of children around the world are exposed to SADs with no viable non-neurotoxic agents approved for clinical use. Allopregnanolone (AlloP) has well-established sedative effects in adults and neonates. AlloP and many SADs produce sedation/anesthesia through allosteric modulation of GABAA receptors, which is one of two principal mechanisms behind SAD-induced neurotoxicity. Evidence suggests AlloP has the unique capacity to regulate key apoptotic factors in adults and is widely involved with critical stages of neurodevelopment, indicating this neurosteroid might serve as a …
Influences Of Salvinorin A And Sex Differences On Depressive- And Anxiety-Like Behaviors In A Chronic Mild Stress Paradigm, Sarah Mitchell
Influences Of Salvinorin A And Sex Differences On Depressive- And Anxiety-Like Behaviors In A Chronic Mild Stress Paradigm, Sarah Mitchell
Theses
Kappa opioid receptors are colocalized with dopamine receptors and are frequently associated with depression, anxiety, stress, and drug use and abuse. KOR antagonism has widely been considered anti-depressive and anxiolytic in animal models while agonism is pro-depressive and anxiogenic. However, recent findings suggest that SalvA, a natural kappa agonist derived from a plant in the mint family, can reduce depressive- and anxiety-like behavior in rats. The current study investigated the effects of chronic mild stress on behavior, attenuation by SalvA, and sex differences. 52 Long-Evans rats, 26 males and 26 females, were exposed to six weeks of CMS. Animals received …
Adrenal Steroids Uniquely Influence Sexual Motivation Behavior In Male Rats, George Taylor, Joshua Dearborn, Susan Maloney
Adrenal Steroids Uniquely Influence Sexual Motivation Behavior In Male Rats, George Taylor, Joshua Dearborn, Susan Maloney

The androgenic adrenal steroids dehydroepiandrosterone (DHEA) and 4α-androstenedione (4-A) have significant biological activity, but it is unclear if the behavioral effects are unique or only reflections of the effects of testosterone (TS). Gonadally intact male Long-Evans rats were assigned to groups to receive supplements of DHEA, 4-A, TS, corticosteroid (CORT), all at 400 µg steroid/kg of body weight, or vehicle only for 5 weeks. All males were tested in a paradigm for sexual motivation that measures time and urinary marks near an inaccessible receptive female. It was found that DHEA and 4-A supplements failed to influence time near the estrous …
Limits Of Learning Enhancements With Nicotine In Old Male Rats, George Taylor, Carl Bassi, Juergen Weiss
Limits Of Learning Enhancements With Nicotine In Old Male Rats, George Taylor, Carl Bassi, Juergen Weiss

Findings with young adult humans and animal models suggest that nicotine may serve both neuroprotective and cognition enhancing roles in old animals. A pair of experiments was conducted to examine drug-induced modification of the cholinergic nicotinic receptor subtype on rates of learning by young and aged rats. In experiment I males (4-7 months or 20-25 months old) were administered nicotine (0.0, 0.3 or 0.7 mg/kg injected s.c. daily) and tested in both a T-maze non-spatial discrimination paradigm and a hole board spatial task. Nicotine failed to improve acquisition by young animals on either task. Nicotine also failed to improve non-spatial …
