The Influence Of Depressive Symptoms On Frn Amplitude: An Eeg Study, Jonathan Burton Dec 2018

The Influence Of Depressive Symptoms On Frn Amplitude: An Eeg Study, Jonathan Burton

USC Aiken Psychology Theses

Background: Individuals diagnosed with depression demonstrate differences in neural activation patterns detectable using electroencephalogram (EEG). One of these differences has been specifically linked with the event-related potential (ERP) component called feedback-related negativity (FRN). In participants diagnosed with depression, the FRN has been shown to have larger amplitudes in response to negative feedback. However, previous research has only specifically looked at the difference of this amplitude between groups, specifically those with and those without a diagnosis of depression. Objective: The goal of the current study was to examine whether a continuous range of depressive symptoms in participants can predict FRN amplitudes, …


Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott Jul 2018

Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott

Masters Theses

Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …

A Program Evaluation Of A Drug And Alcohol Family Treatment Program, Katrina Ramirez

Doctoral Dissertations

The current study is a program evaluation at John Muir Behavioral Health, Center for Recovery. The research determined the effectiveness of the program at Center for Recovery that is offered to patients that struggle with substance use disorder and their families. The purpose of this study is to assess patients’ behavioral, cognitive and social/environmental factors as it relates to their commitment to sobriety and examine how the involvement of family members influences the patient’s recovery process. I utilized a mixed methodology of quantitative and qualitative interviews of patients and family members. The findings suggest depressive symptoms were negatively correlated with …


Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton May 2018

Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton

Honors Projects

A literature review discusses yoga and health involving oxytocin creates the premise for a proposal combining the knowledge of yoga and its health benefits along with oxytocin's potential involvement during group exercise, yoga specifically. The proposed study's results of oxytocin measures and questionnaires have the potential to develop an understanding of the possible impacts of yoga on mood, particularly relationships between group exercise and yoga, which may help develop forms of group exercise or implement group yoga to assist or replace treatment for stress-caused or stress-related disorders.


Modeling The Psychiatric Aspects Of Polycystic Ovary Syndrome And Induced Stress, Danielle Peecher Jan 2018

Modeling The Psychiatric Aspects Of Polycystic Ovary Syndrome And Induced Stress, Danielle Peecher

All Master's Theses

Polycystic ovary syndrome (PCOS) is an endocrine disorder in women that is characterized by excess testosterone and is associated with increased risk of infertility. Women with PCOS also show higher rates of depression and anxiety. Modeling PCOS in mice via administration of dihydrotestosterone (DHT) results in physiological alterations that are consistent with the physiological symptoms of PCOS in women. While some studies have investigated behavioral changes in PCOS mouse models, findings have varied. Thus, the current research examined whether a PCOS model with an additional stress factor resulted in behavioral changes. To create a stress condition, subjects were implanted with …
