Abstract
This chapter focuses on the balance and consider adolescence as a pivotal stage in development in explaining both risk and resilience. It discusses neuroimaging evidence suggesting that adolescence is associated with the functional and structural reorganisation of three distinct, although highly related, biobehavioural systems, i.e. the stress-regulation, attachment/reward and mentalizing systems, as well as other related neural systems such as systems for cognitive control. The implications of the reorganisations in these three biobehavioural systems in adolescence, and their role in explaining both vulnerability and resilience, are vast and deserve our attention. The human biobehavioural stress system is a complex system of neural structures that are involved in detecting, integrating, and responding to threat. Two areas of reward are central in adolescence: relationships, with a developmental shift towards growing importance of peer and romantic relationships, and agency/achievement.
