Behavioral Epigenetics is the study of how environmental factors affect alterations in behavior, addressing the fundamental mechanisms that shape development and individual vulnerability/resilience to adverse behavioral outcome. With an understanding of the molecular mechanisms involved in epigenetic modulation, researchers believe it will be possible to develop targeted therapies for those individuals in whom it malfunctions. This volume will address current understanding of the roles of epigenetic processes at the molecular/cellular level, their impact on neural development and behavior.
