A baby's smile is a natural high
Date:7/6/2008

rength of the reaction depended on the baby's facial expression, he said.

"The strongest activation was with smiling faces," he said. There was less effect from pictures of their babies with sad or neutral expressions.

"We were expecting a different reaction with sad faces," he said. In fact, they found little difference in the reaction of the mothers' brains to their own babies' crying face compared to that of an unknown child.

Overall, the mothers responded much more strongly to their own infants' faces than to those of an unknown baby.

"Understanding how a mother responds uniquely to her own infant, when smiling or crying, may be the first step in understanding the neural basis of motherinfant attachment," said Strathearn.
