Second pregnancy uniquely alters the brain, study finds

A second pregnancy uniquely alters a woman's brain, differing from the changes seen after a first pregnancy, new research reveals. The study found that while a first pregnancy significantly impacts self-reflection networks, a second pregnancy shows greater shifts in regions processing sensory stimuli and attention, potentially aiding in caring for multiple children. This research builds on previous findings of gray matter reduction and improved neural connectivity during pregnancy, suggesting ongoing brain adaptation to motherhood.
