Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold
Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold
Honors College Theses
In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …
The Effects Of Mindfulness Meditation On Rumination In Depressed People, Rachel A. Sluder
The Effects Of Mindfulness Meditation On Rumination In Depressed People, Rachel A. Sluder
Honors Theses and Capstones
Mindfulness meditation is a practice of focus, awareness, and non-judgmental acceptance of one's thoughts (Deyo et al., 2009; Kenny et al., 2007). Rumination is a maladaptive pattern of thought that is common in people with depression and other mood disorders. It can lead to further episodes of depression, and can be very destructive in that way (Nolen-Hoeksema, 2008). This paper reviews several studies on mindfulness meditation, depression, and rumination, with a focus on certain areas and phenomena such as alpha asymmetry (Keune et al 2013) and gamma band activity (Berkovich-Ohana et al., 2012). Modalities such as fMRI and EEG are …
Traumatic Brain Injury: The Relationship Of Psychosocial Variables And Location Of Injury To Post-Injury Depression, Alicia L. Smith
Traumatic Brain Injury: The Relationship Of Psychosocial Variables And Location Of Injury To Post-Injury Depression, Alicia L. Smith
Theses, Dissertations and Capstones
Traumatic Brain Injury (TBI) affects nearly 1.4 million people in the United States annually, and of these, 10% to 77% will experience post-injury depression. Psychosocial variables such as previous substance and alcohol abuse, prior mental illness, low educational attainment, and poverty have been identified as possible risk factors. Additionally, the location of injury appears to play a key role particularly if the injury occurs in the left hemisphere. This study examined archival data from brain-injured patients in an effort to better understand the factors related to post-TBI depression. Past medical records of brain-injured adults (N = 52) were reviewed …
Preweanling Exposure To Selective Catecholamine Transporter Inhibitors Differentially Effects Morphine-Induced Antinociception In Adulthood, Joseph Marco Valentine
Preweanling Exposure To Selective Catecholamine Transporter Inhibitors Differentially Effects Morphine-Induced Antinociception In Adulthood, Joseph Marco Valentine
Theses Digitization Project
The purpose of this project is to determine how early methylphenidate exposure alters opioid receptor functioning in adulthood. To this end, we will administer selective monoamine transporter inhibitors for dopamine and norepinephrine (GBR-12904 and atomoxetine) during preweanling period and assess opioid function in adult rats by testing morphine-induced antinociception using the hot-plate and tail-flick tasks. In order to assess the effects of methylphenidate use on brain functions during development, investigations have been conducted in rats using ages roughly analogous to early and late childhood.
Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Adolescent And Adult Nicotine Exposure On The Acquisition Of Methamphetamine Self-Administration And The Reinstatement Of Extinguished Methamphetamine-Seeking In Male Rats, Joseph Allan Pipkin
Theses Digitization Project
This study sought to determine the individual and combined contribution of adolescent and adult nicotine exposure on METH self-administration and METH-seeking behavior in male rats. Nicotine is a commonly abused substance among adolescents and is believed to be a "gateway" to other drugs of abuse. In support of the gateway hypothesis, cigarette smoking during adolescence is related to increased methamphetamine (METH) use in adulthood.
The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi
Honors Projects
The ability of homing pigeons to return to their loft from unknown places has fascinated scientists for centuries. It is well established that homing pigeons, like migratory birds, posses an innate magnetic inclination compass to determine direction by measuring the angle between the magnetic field vector and the Earth's surface. Recent work has indicated that the avian magnetic compass is light mediated and appears to mediate magnetic information to the brain. This occurs via a visual pathway with processing in the visual Wulst area of the forebrain. There is, however, also evidence from other avian species that magnetic direction may …
Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul
Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul
Theses and Dissertations--Psychology
Borderline Personality Disorder (BPD) is a disabling condition characterized by chronic emotion dysregulation and behavioral impulsivity. Prospective studies that test proposed mechanisms of within-person change in BPD hold the key to improving symptom predictability and control in this disorder. A small body of evidence suggests that fluctuations in estradiol such as those occurring naturally at ovulation during the monthly female reproductive cycle may increase symptoms in women with BPD (DeSoto et al., 2003). Furthermore, there is preliminary evidence that both self-esteem and feelings of social rejection are highest at ovulation, when estradiol peaks (Durante and Hill, 2009; Eisenlohr-Moul et al., …
Prenatal Stress, Depression, And Herpes Viral Titers, Pao-Chu Hsu
Prenatal Stress, Depression, And Herpes Viral Titers, Pao-Chu Hsu
USF Tampa Graduate Theses and Dissertations
Recent studies suggest that some cases of prenatal depression may be associated with reactivation of latent infections of the herpesvirus family. The possible relationships among stress, prenatal depression, and herpes viral reactivation in pregnancy are understudied and the molecular pathways such as the neuroimmune biogenic amine pathway are unidentified. Chronic stress shifts the T helper-1 cell (Th1) cytokine profile to a Th2 profile, which favors virus induced pathogenesis and survival. Pregnancy is also associated with a similar Th2 dominance. In non-pregnant individuals, exposure to psychological or physical stress may be associated with latent herpes viral reactivation and could result in …
