Motherhood doesn’t just change your life. It also changes your brain.
New research, reported last month at a neuroscience meeting in San Diego, suggests that having babies permanently alters brain function.
If you’re a rat, it makes you better at finding and killing dinner quickly. If you’re a human, it helps you distinguish between your baby’s cry and that of other children.
In either case, it’s something fathers just don’t get. Only mothers undergo these changes.
