Giving birth to a better brain: Do babies sharpen parents' minds?
By Erica Noonan


From the article:

"Women with small children have long been saddled with an unflattering stereotype -- incompetent, dull-witted, frazzled, and preoccupied with domestic affairs. The derogatory cliches vary, from ''maternal amnesia" in medical circles, to the colloquial ''placenta brain" in the United States and ''porridge brain" in Great Britain. But a new body of research -- so far still mostly in animals -- is fueling the idea that motherhood may actually rewire the brain, making mothers (and involved fathers) more perceptive, competitive, efficient, and even socially aware. And sociological studies suggest that most of the symptoms of ''mommy brain" may be due as much to exhaustion and stress as biology.

The transforming experiences of pregnancy, labor, and caring for small children ''enables the brain to process information much differently than it did before," he said.

Kinsley and other researchers have found that beginning a few weeks after giving birth, a female rat's cognitive abilities -- particularly smell and visual perception -- start to expand. Rats nursing a litter of pups discover and catch prey three times as quickly as virgin rats, he said.

Kinsley's analysis of brain tissue from rats in late pregnancy showed that neural pathways in the hippocampus, the center of learning and memory, were essentially ''remapped."

The changes, Kinsley and others said, probably come partly from the experience of pregnancy and labor, when elevated levels of estrogen, cortisol, and other hormones literally bathe the brain. The presence of pups and the demands of caring for them also contributes to brain changes in mother rats -- even caretaker rats who have never been pregnant. In repeated studies, mother rats with pups have proven to be bolder and quicker at finding hidden food.

''We believe the pups are having an effect on the mother, enhancing her efficiency," Kinsley said. ''The pups have a paw in their own survival. The mom isn't a passive caregiver. Rather, absorbing sensory information from the pups has an influence on her brain."

The phenomenon hasn't yet been studied in women, but the rodent studies have important implications for humans, said Kelly Lambert, chair of the psychology department at Randolph Macon College in Virginia.

''Rodents have all the same brain parts we have," she said. ''Human brains are thicker and more complex, but as a model it's a very reasonable place to start."
