Pregnancy leads to striking changes in the brain, including alterations in gray matter and regions involved in self-perception, according to a new study.

The findings suggest that these neurological changes may promote bonding between mother and baby and could play a role in the identity shift that many women feel when they become new mothers, the researchers said.
