    Dr. Ycaza Herrera is an Assistant Professor of Research at the USC Leonard Davis School of Gerontology. Her research focuses on how changes in hormone status across the adult female lifespan affect the physiological response to stress and cognition. To investigate how ovarian hormone levels affect the adrenal cortisol and progesterone responses to stress and cognition, she studies post-menopausal women using and not using estradiol therapy, pre-menopausal women not using hormonal contraceptives during various points of the natural menstrual cycle, and women using hormonal contraceptives during the different phases of the hormonal contraceptive cycle.

    Methods used in her research program involve behavioral testing, neuroimaging using functional magnetic resonance imaging (fMRI), and enzyme-linked immunosorbent assays (ELISA) for hormone measurements.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
