Fortunately for those who have the nature of motherhood. Though not yet a mother, a woman who had a gentle nature and loving like a mother-cells can produce new nerve cells in the brain that might be made more intelligent. Thus the results of the study researchers.

At least that’s what diiungkapkan study by researchers from Tufts University’s Cummings School of Veterinary Medicine, London. Although this new study conducted on mice, but the analogous rat brain as a human brain was shown to have growth of new cells when a mother’s activity.

In his study, mice who had never given birth were given a pet to evoke a sense of motherhood. The rats were stimulated to behave like a mother protecting pets including using his body to put her to bed in the nest. From mouse brain scans during the study progresses, an increase in the number of nerve cells in the rat brain.

Previous studies had mentioned that rodents are lactating (lactation) increased the formation of nerve cells in the brain. However, this study is the first study showing the benefits of maternal characteristics in living things that do not have kids.

Researchers focused the study on the part of the brain subventricular, which is part of the brain that produce cells associated with the introduction of smells and maternal traits. Adult female mice are reported to be motherhood has more nerve cells in the brain than rats that never connected with the children.

Yet researchers still do not know the cause of increased production of brain cells in mice. But the researchers speculate it is caused by the hormone prolactin, which stimulates maternal behavior and the formation of nerve cell formation in the brain. The more often associated with children’s production of nerve cells in the brain will increase.

“This study shows that a maternal nature is a benefit and blessing. Proven to behave like a mother, the new cells will grow in the brain and it is not impossible to make someone more intelligent. Fortunately for those who will and has become a mother,” said the researcher, Robert Bridges as quoted by LiveScience, Tuesday (22/12/2009).

This study is published in the Journal of Brain Research Bulletin and funded by the National Institutes of Health grants.
