Early Brain Development in Twins
In Brief
An observational study for Twin Brain Development. Completed, enrolled 550 participants across 1 site.
Detailed Summary
The purpose of this study is to study the role of genes and environment in early brain development using a twin approach. The investigators will use magnetic resonance imaging (MRI) to study brain structure and it's relationship to cognitive development. Specifically, the investigators will study cortical gray and white matter volumes, volumes of subcortical structures and cerebellum, as well as diffusion properties in major white matter tracts using DTI tractography.
