Pregnancy acually re-wires your brain


Becoming a parent is a life-altering experience. It's also a mind-altering experience, according to new research—literally. Brain scans of new moms showed that the areas involved in processing social information got re-wired after their first pregnancy, and those changes lasted for at least two years. The changes may help new moms bond with and take care of their babies.

The findings, published Monday in Nature Neuroscience, provide the first evidence that pregnancy causes long-term changes in the human brain. But they're not altogether surprising. Puberty (which, like pregnancy, involves raging hormones) is known to reorganize adolescent brains.
