Examining the role of endogenous opioids in learned odor-stroke associations in infant rats.

abstract：:The aim of this study was to determine the impact of maternal age on executive function and the moderating effects of women's maternal status and early-life experiences. Four groups of women were assessed as a function of their age (teens vs. adults) and maternal status (mothers vs. nonmothers). Participants completed...
