We investigate the development of cortical structure-function coupling in children longitudinally scanned at 1, 2, 4, and 6 years old. We found that regional patterns of structure-function coupling in early childhood that were consistent with adult patterns.

In the largest analysis of postpartum depression (PPD) genetics, we have provided estimates of the genetic contribution to this debilitating disorder. Also, we have shown that PPD has similar genetics to other psychiatric traits. Lastly, PPD associated genetic regions may affect neurons also targeted recently approved therapeutics specifically for PPD...
