By using a surface-based method (FreeSurfer), the cortical thickness measurement was performed on young adolescents born preterm with very low birth weight (n = 15, birth weight < 1500 g) and age-matched term born controls (n = 17). The preterms, who present no brain injuries, showed a thicker cortex in parietal, occipital, and temporal regions compared to the controls, suggesting the delay of cortical thinning.
