Developmental trajectories during adolescence in males and females: A cross-species understanding of underlying brain changes
چکیده انگلیسی

Adolescence is a transitional period between childhood and adulthood that encompasses vast changes within brain systems that parallel some, but not all, behavioral changes. Elevations in emotional reactivity and reward processing follow an inverted U shape in terms of onset and remission, with the peak occurring during adolescence. However, cognitive processing follows a more linear course of development. This review will focus on changes within key structures and will highlight the relationships between brain changes and behavior, with evidence spanning from functional magnetic resonance imaging (fMRI) in humans to molecular studies of receptor and signaling factors in animals. Adolescent changes in neuronal substrates will be used to understand how typical and atypical behaviors arise during adolescence. We draw upon clinical and preclinical studies to provide a neural framework for defining adolescence and its role in the transition to adulthood.


► We review adolescence as a heterogeneous developmental stage.
► Neuroanatomical changes are juxtaposed with environmental influences and demands.
► Developmental trajectories interact with sex-dependent changes.
► We discuss the evolution of understanding with increasingly sensitive research tools.
