Development of the adolescent brain: Implications for executive function and social cognition

Abstract

Adolescence is a time of considerable development at the level of behaviour, cognition and the brain. This article reviews histological and brain imaging studies that have demonstrated specific changes in neural architecture during puberty and adolescence, outlining trajectories of grey and white matter development. The implications of brain development for executive functions and social cognition during puberty and adolescence are discussed. Changes at the level of the brain and cognition may map onto behaviours commonly associated with adolescence. Finally, possible applications for education and policy are briefly considered. © 2006 The Authors Journal compilation 2006 Association for Child and Adolescent Mental Health.
