Longer Breast-Feeding May Be Key to Bigger Brains
Date:3/30/2011

WEDNESDAY, March 30 (HealthDay News) -- Longer periods of pregnancy and breast-feeding in mammals are associated with larger brain growth in offspring, which explains why human babies remain dependent on their mother for so long, say researchers.

They also said the findings from their study of humans and 127 other mammal species offer further proof that breast-feeding is good for brain development and support the World Health Organization's recommendation that babies should be breast-fed exclusively for their first six months of life, followed by continued breast-feeding (along with other foods) up to age 2 or longer.

The researchers at the University of Durham in the U.K. found that brain size relative to body size was most closely associated with maternal investment -- the length of time a mother spends carrying her offspring in pregnancy and how long she suckles her young.

The length of pregnancy determines offspring's brain size at birth and the amount of time spent suckling affects brain growth after birth.

For example, humans have nine-month pregnancies and breast-feed their babies for up to three years. This is necessary to fuel the growth of the brains, which have an average volume of 1,300 cubic centimeters (cc) in adults. Fallow deer have about the same body weight as humans but are only pregnant for seven months, followed by a suckling period of up to six months. Their adult brain size is 220cc, six times smaller than the human brain.

"We already know that large-brained species develop more slowly, mature later and have longer lifespans, but what has not always been clear is why brains and life histories are related," lead investigator and anthropology professor Robert Barton said in a university news release.

"One theory is that large brains increase lifespan by making the animal more generally flexible in its behavioral responses to unpredictable challenges, permitting slower life histories
