The brain is an endocrine organ, sensitive to the rhythmic changes in sex hormone production
that occurs in most mammalian species. In rodents and nonhuman primates, estrogen …

The prefrontal cortex (PFC) is exquisitely sensitive to its neurochemical environment. Minor
fluctuations in cortical dopamine (DA) can profoundly alter working memory, a PFC-…

A major challenge in neuroscience is to understand what happens to a brain as it ages. Such
insights could make it possible to distinguish between individuals who will undergo typical …

Dopaminergic drugs affect a variety of cognitive processes, but the direction and extent of
effects vary across individuals and tasks. Paradoxical effects are observed, by which the same …

Recent negative focus on women's academic abilities has fueled disputes over gender
disparities in the sciences. The controversy derives, in part, from women's relatively poorer …

Women constitute half of the world’s population, yet neuroscience research does not serve
the sexes equally. Fifty years of preclinical animal evidence documents the tightly-coupled …

Two samples of market oysters, primarily from retail establishments, were collected twice each
month in each of nine states during 2007. Samples were shipped refrigerated overnight to …

OBJECTIVE: To report the spectrum of iris lesions based on patient age at presentation.
DESIGN: Retrospective, nonrandomized, single-center case series. PARTICIPANTS: We …

Next-generation sequencing (NGS) workflows applied to bronchoalveolar lavage (BAL)
fluid specimens could enhance the detection of respiratory pathogens, although optimal …

Objective: Few have characterized cognitive changes with age as a function of menopausal
stage relative to men, or sex differences in components of memory in early midlife. The study …
