Epigenetic Effects of Early Developmental Experiences

Abstract

Early-life adversity can affect brain development and behavior. Emerging evidence from studies on both humans and rodents suggests that epigenetic mechanisms may play a critical role in shaping our biology in response to the quality of the environment. This article highlights the research findings suggesting that prenatal maternal stress, postnatal maternal care, and infant neglect/abuse can lead to epigenetic variation, which may have long-term effects on stress responsivity, neuronal plasticity, and behavior. © 2011.
