A new study offers the first detailed map of the human brain throughout and after pregnancy. It was published in the journal Nature Neuroscience on Monday.

Neuroscientist Liz Chrastil got the unique chance to see how her brain changed while she was pregnant and share what she learned in a new study that offers the first detailed map of a woman’s brain throughout gestation.

The transition to motherhood, researchers discovered, affects nearly every part of the brain.

Although the study looks at only one person, it kicks off a large, international research project that aims to scan the brains of hundreds of women and could one day provide clues about disorders like postpartum depression.
