Effect of stress and BDNF genotype on cortical volume across age. Left Panel: Cortical volume in increases with age in both PI (stressed) and control children. Middle and Right Panel: The two genotype groups did not differ from each other in the non-stressed group (middle panel), whereas Met carriers in the stressed group (right panel) tended to show increasingly smaller brain volumes over the course of development relative to their Val/Val peers.
