Mothers are "hard-wired" to protect their babies
Last Updated(Beijing Time):2008-03-11 15:16
The same instinct that makes mothers in the animal kingdom protect their offspring against danger appears to be a part of the human mother's brain as well, according to media reported reports Monday. 

Researchers in Tokyo, Japan, made magnetic resonance images (MRIs) of 13 mothers, each of whom had a child about 16 months old. The mothers were taken out of the room where they had been with their babies, and a videotape was made of the toddlers crying and reaching for their mothers. 

When each mother saw the image of her child in distress, the MRI showed a markedly different neural reaction than when she was watching other mothers' babies.

This dramatic brain pattern reaction seems "to be biologically meaningful in terms of adaptation to specific demands associated with successful infant care," media reports quote the study authors as noting in the study.

No similar study has yet been done with fathers. The research was published in the February 2008 issue of the journal Biological Psychiatry.
