Regaining Effort-Based Food Motivation: The Drug Methylphenidate Reverses The Depressive Effects Of Tetrabenazine In Female Rats, Deanna Pietrorazio May 2022

Regaining Effort-Based Food Motivation: The Drug Methylphenidate Reverses The Depressive Effects Of Tetrabenazine In Female Rats, Deanna Pietrorazio

Honors Scholar Theses

Tetrabenazine (TBZ), a vesicular monoamine transporter type 2 (VMAT-2) inhibitor, depletes dopamine and induces motivational deficits and other depressive symptoms in humans. Methylphenidate (MPH) is a dopamine transport blocker that is used to enhance motivational function. Previous studies have shown that in male rats, TBZ induces a shift in effort-related choice such that a low-effort bias is induced. In male rats this occurs at a dose range of 0.75-1.0 mg/kg TBZ, and this effect is reversible with co-administration of MPH. Recent studies have shown that females need a higher dose of TBZ (2.0 mg/kg) to show the low-effort bias. The …


Social Work Trauma Interventions: Dialectical Behavioral Therapy, Kassie Baumann May 2018

Social Work Trauma Interventions: Dialectical Behavioral Therapy, Kassie Baumann

Senior Honors Theses

According to Lynne Weilart (2013), in her article on the reasons why people seek out therapy, trauma is the number one reason people attend counseling. Many different trauma-informed approaches are designed specifically to address the consequences of trauma and to facilitate healing. Some of these approaches are as follows: Cognitive Behavioral Therapy (CBT); Dialectical Behavioral Therapy (DBT);Mentalization Based Therapy (MBT); Trauma Systems Therapy (TST); Trauma Assessment Pathway (TAP); and Attachment, Self-Regulation, and Competency (ARC) (de Arellano, Danielson, Ko, & Sprauge, 2008). The effectiveness of each trauma intervention will be examined. DBT is one of these trauma interventions that is growing …


Norepinephrine Involvement In The Intermittent Swim Stress-Induced Deficit In Spatial Learning And Memory, Emily Elgert Apr 2013

Norepinephrine Involvement In The Intermittent Swim Stress-Induced Deficit In Spatial Learning And Memory, Emily Elgert

Honors Theses and Capstones

Learning and memory impairments are often caused by stress disorders including depression. The present study investigated the involvement of norepinephrine in the swim stress-induced deficits of spatial learning and memory. Exposure to intermittent swim stress (ISS) followed by learning and memory tests in the Morris water maze (MWM) were used to investigate this relationship. The ISS paradigm consists of intermittent exposure to cold water, producing stress responses in rats. Reboxetine, a norepinephrine selective reuptake inhibitor (NSRI), was employed to investigate whether this compound reverses the ISS-induced deficit. In other words, rats exposed to the ISS, were hypothesized to experience impaired …


Sexual Reward And Depression, Andrea R. Di Sebastiano Oct 2012

Sexual Reward And Depression, Andrea R. Di Sebastiano

Electronic Thesis and Dissertation Repository

Sexual behavior in male rats is a complex rewarding behavior and many neurotransmitters and neuropeptides play an important role in mediation of sexual performance, motivation and reward. The hypothalamic neuropeptide orexin has been shown play a key role in reward associated with food and drugs of abuse, but the role of this neuropeptide in control of sexual performance, motivation and reward is currently unclear. First, it was shown that orexin neurons in the hypothalamus are activated during sexual performance and reward. Next, using cell specific lesions of orexin neurons it was demonstrated that orexin is involved in arousal and anxiety, …
