© News.com.auResearch from the University of Washington says living cells from sons can live in their mother's brains for her entire life.
Women have claimed an intuitive link with their children for centuries. Now science has discovered their living cells in the brains of their mothers.
The bond between a pregnant mother and their unborn child is both physical and psychological. It relies totally on her for nutrition, warmth, comfort and protection.
A new study published in the science journal PLOS ONE suggests elements of this mother-baby connection may linger long after birth.
It found fetal DNA and cells from male children cross the blood-brain barrier and end up living in the mother's brain.
The University of Washington research found 63 per cent of mothers have the DNA of their boys living in their female brains.
The physical presence is not short-lived. Scientists say some of the offspring's cells can stay with the mother for their entire lives.
The oldest mother in whom their male child's DNA was discovered was 94 years old.
Researchers say they do not know why the cells end up in the brains of mothers. And the cells don't end up in any one particular spot. They can be found throughout the mother's brain.
Whether or not the cells have any effect on the mother is not yet known.
However, the study found women suffering Alzheimer's disease were less likely to be carrying them.
So perhaps this is why certain 'extremists' seek to control females? To get back all their cells? It could explain this issue for those not preferring to share, and perhaps a marker of tendencies present from birth towards one's spiritual orientation.
