Children School Functions and Brain Development Project (CBD)
The CBD project is an accelerated longitudinal study that recruited 6 to 12 year-old students from primary schools in Beijing, China. Data was collected from July 28th, 2016 to May 24, 2021. The study consists of a longitudinal structural and functional MRI dataset comprising normally developing children. Participants underwent 2 to 4 repeated MRI scans at approximately 1-year intervals. At baseline, 798 participants were included. At the first follow-up, 477 participants were included. At the second follow-up, 361 participants were included.
