Evidence from a quiet MRI: Breastfeeding benefits babies’ brains

A study using brain images from “quiet” MRI machines adds to the growing body of evidence that breastfeeding improves brain development in infants. Breastfeeding alone produced better brain development than a combination of breastfeeding and formula, which produced better development than formula alone.

PROVIDENCE, R.I. [Brown University] — A new study by researchers from Brown University finds more evidence that breastfeeding is good for babies’ brains.

The study made use of specialized, baby-friendly magnetic resonance imaging (MRI) to look at the brain growth in a sample of children under the age of 4. The research found that by age 2, babies who had been breastfed exclusively for at least three months had enhanced development in key parts of the brain compared to children who were fed formula exclusively or who were fed a combination of formula and breastmilk. The extra growth was most pronounced in parts of the brain associated with language, emotional function, and cognition, the research showed. (more…)

Following the Crowd: Brain Images Offer Clues to How and Why We Conform

What is conformity? A true adoption of what other people think—or a guise to avoid social rejection? Scientists have been vexed sorting the two out, even when they’ve questioned people in private.

Now three Harvard University psychological scientists have used brain scans to show what happens when we take others’ opinions to heart: We take them “to brain”—specifically, to the orbitofrontal cortex and nucleus accumbens. These regions compute what we value and feel rewarded by, both primitive things like water and food and socially meaningful things like money. (more…)
