Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan

Dissertations

Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …

Externalizing Behavior Predicts Differential Patterns of Substance Use among Adolescents by Race

Early substance use is associated with negative developmental outcomes and chronic disease. Adolescent externalizing behavior (e.g., rule-breaking, lying, aggression) is a consistent predictor of adolescent substance use. However, the association between externalizing behavior and different substances (e.g., alcohol, cannabis, nicotine) is unclear. It is important to clarify these relationships by race as previous research has demonstrated that substance use risk factors for Black youth differ from those for White youth, with whom much research has been conducted.

Non-Hispanic Black (n=16) and White (n = 20) adolescents ages 14-18 …
