Examining Limbic Sexual Dimorphisms In Schizophrenia, Kennedy S. Madrid
Examining Limbic Sexual Dimorphisms In Schizophrenia, Kennedy S. Madrid
Undergraduate Honors Theses
Schizophrenia is a mental disorder that affects a significant number of individuals in the United States and can have numerous different symptoms. Recently, interest in the differences between the neuroanatomy of individuals with schizophrenia and individuals without schizophrenia has emerged, specifically the sexual dimorphism in individuals with schizophrenia. This study aimed to gain a better understanding of the sexual dimorphisms of two structures in the limbic system: the hippocampus and amygdala. Data was harmonized and analyzed from two datasets to determine the sexual dimorphic factor of these structures in healthy controls and individuals with schizophrenia. Demographic features were also taken …

Levels Of Parp1-Immunoreactivity In The Human Brain In Major Depressive Disorder, Aamir Shaikh

MDD is a severe and debilitating disorder that is associated with a growing global economic burden due to reduced workplace productivity along with increased healthcare resource utilization. Furthermore, depression markedly enhances the risk for suicide, mortality that is especially worrisome given that 30% of depressed individuals have an inadequate response to current antidepressants. This inadequacy of antidepressants necessitates the discovery of a better understanding of the pathobiology of MDD. Most current antidepressants work through monoamine neurotransmitters, and their relative efficacy in depression led to the now dated monoamine-deficiency hypothesis. The limited usefulness of antidepressants has led to a reinvigorated search …

Neuromodulation Therapy Mitigates Heart Failure Induced Hippocampal Damage, Timothy P. Diperi
Undergraduate Honors Theses
Cardiovascular disease (CVD) is the leading cause of death in the United States. Nearly half of the people diagnosed with heart failure (HF) die within 5 years of diagnosis. Brain abnormalities secondary to CVD have been observed in many discrete regions, including the hippocampus. Nearly 25% of patients with CVD also have major depressive disorder (MDD), and hippocampal dysfunction is a characteristic of both diseases. In this study, the hippocampus and an area of the hippocampal formation, the dentate gyrus (DG), were studied in a canine model of HF. Using this canine HF model previously, we have determined that myocardial …
Locus Coeruleus And Hippocampal Tyrosine Hydroxylase Levels In A Pressure-Overload Model Of Heart Disease, Luke A. Johnson
Locus Coeruleus And Hippocampal Tyrosine Hydroxylase Levels In A Pressure-Overload Model Of Heart Disease, Luke A. Johnson
Undergraduate Honors Theses
Studies have indicated that approximately 30% of people with heart disease experience major depressive disorder (MDD). Despite strong clinical evidence of a link between the two diseases, the neurobiological processes involved in the relationship are poorly understood. A growing number of studies are revealing similar neuroanatomical and neurochemical abnormalities resulting from both depression and heart disease. The locus coeruleus (LC) is a group of neurons in the pons that synthesize and release norepinephrine, and that is known to play a significant role in depression pathobiology. For example, there is evidence that tyrosine hydroxylase (TH) is elevated in the LC in …
