How genes help shape brain after birth

"we examine how genetic effects on cortical thickness change longitudinally over childhood and adolescence using a large genetically informative imaging sample. We find rapid changes in genetic effects in early childhood, with stabilization in late adolescence. The areas with the greatest changes include evolutionarily novel regions. These findings have implications for future molecular genetic studies of imaging endophenotypes and further our sparse understanding of how genes help to shape the brain after birth."
