Overview
- Researchers conducted 26 MRI scans on a first-time mother from before conception to two years postpartum.
- The study found a 4% reduction in gray matter volume in over 80% of the brain regions examined.
- Increases in white matter integrity were observed during the second trimester, returning to baseline by birth.
- The changes in the brain are linked to rising levels of hormones such as estradiol and progesterone.
- The research aims to deepen understanding of conditions like postpartum depression and the brain's adaptability during pregnancy.
