We are constantly bombarded by environmental distractors in daily life which interfere with internal, ongoing goals, thus cognitive control processes need to be in place to adapt to maintain these goals in light of the environmental demands. These cognitive processes (generally referred to cognitive control) are thought to be adjusted reactively or proactively to deal with distractors. There is little evidence on how state anxiety dynamically interacts with these two modes of cognitive control. Taking advantage of a multimodal methodology, through two experiments, we replicated existing findings of reactive and proactive control processes via utilizing a Flanker task in a …

Data-Driven Approach To Dynamic Resting State Functional Connectivity In Post-Traumatic Stress Disorder, Carissa Weis
Theses and Dissertations
Posttraumatic stress disorder (PTSD) is a heterogenous psychological disorder that may result from exposure to a traumatic event. Using functional magnetic resonance imaging (fMRI), symptoms of PTSD have been associated with aberrations in brain networks that emerge in the absence of a given cognitive demand or task, called resting state networks. Most previous research in resting state networks and PTSD has focused on aberrations in the static functional connectivity among specific regions of interest (ROI) in the brain and within canonical networks constrained by a priori hypotheses. However, dynamic fMRI, an approach that examines changes in brain network characteristics over …
The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette
The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette
Theses and Dissertations
The beneficial effects of exercise and cardiopulmonary fitness on general health, quality of life, and reduction of mortality are well known in older adults. There is evidence to support the positive effects of exercise and aerobic fitness on psychiatric and neurocognitive function in children, adults, and older adults. Indeed, many studies have explored the positive effects of aerobic fitness on slowing cognitive decline associated with normal and pathological aging. However, comparatively fewer empirical studies in the literature exist to support and understand the effects of aerobic fitness on the developing brain, particularly during adolescence and young adulthood, especially as it …

Shaped By The Environment: The Influence Of Childhood Trauma Exposure, Individual Socioeconomic Position, And Neighborhood Disadvantage On Brain Morphology, Elisabeth Kathleen Webb
Theses and Dissertations
The relationship between an individual’s socioeconomic position (SEP) and their overall physical and mental health has been well demonstrated. Far less is known about how area-level factors, such as neighborhood disadvantage, “get under the skin”. Previous research indicates lower SEP and childhood trauma negatively effects brain structure and function. The hippocampus, amygdala, and ventromedial prefrontal cortex (vmPFC) are particularly vulnerable to adversity. The current study investigated how individual SEP, childhood trauma, and neighborhood disadvantage impact these structures. Two-hundred and fifteen individuals were recruited from an Emergency Department in southeastern Wisconsin. Two-weeks post-traumatic injury, participants completed a structural magnetic resonance imaging …
